Our registered address is AQA, Devas Street, Manchester M15 6EX. AQA Specification A Physical Geography Key Idea (Scale) The amount of ice on a global and continental level has changed in the past.(G+L) Specification Content The last Ice Age (Pleistocene) – time scale and extent of maximum ice cover in the northern hemisphere. Present extent of ice cover. Contrasts and evidence of changes – global temperatures. Unit 6 Ice on the Land Starters Main activities Plenaries 1.http://www.uwsp.edu/geo/faculty/ritte r/geog101/textbook/glacial_systems/gl aciation_causes.html includes a short video clip (National Geographic) hypothesising about the likely effects of a new ice age 1. Describe the evidence for climatic change given in this video http://www.bbc.co.uk/learningzone/clips/evidence-ofclimate-change/1490.html What other evidence would support the idea of climatic change? This video at GATM (Global Warming) considers the evidence for global temperature change http://www.gatm.org.uk/?p=168 1. True false statements. Students can do this as a quiz, or work in teams. Alternatively they guess the correct answers from 2 alternatives: e.g. In the modern world about (10%/30%) of land area (roughly 15,000,000 square kilometres) is covered by glaciers, but during the last Ice Age glaciers covered about (32%/52%) of the total land area. (29/99%) of modern glacial ice is located in the Arctic and Antarctic. In some parts of the Antarctic, the ice has been measured as being over (1500/4,200) metres thick. The Antarctic ice sheet has been in existence for at least (2/40) million years. Glaciers store between (10% and 20%/70% and 80%) of all the freshwater in the world. The land underneath parts of the West Antarctic Ice Sheet may be up to (0.5/2.5) kilometres below sea level. The weight of the ice pushes the land surface down. The south of the United Kingdom has been slowly (falling/rising) since the last ice age , due to the weight of all that ice being removed when it melted 2. Pose initial questions to test knowledge of glaciation. e.g. What are the differences between ice sheets and glaciers? Where would you find examples of each? Where in Britain were there valley glaciers and ice sheets? Which parts of the UK were not covered by ice in the Ice Age? How far did ice sheets extend across Europe? What happened during the interglacial periods? During the glacial advance it would have been possible to walk from the UK to France as there was no English Channel. Why was this? What would southern Britain have been like during the last ice age? 3. Study a world map or atlas. Can you identify which areas are covered in ice? Which continents have the most ice? Which continents have the least ice? How does the scale of glaciers vary in different places? Why do some parts of the world have very little ice? How is it possible for some areas along the equator to be ice covered? 4. Brianstorm glaciation to find out what students know about the topic already. What do they know about ice ages, glaciers, ice caps, melting ice, 2. Predict what will happen to temperature based on graph of climate of past 1 million years What has happened to our climate in the past? Make notes about different periods in history. Annotate graph. Record reasons for changes. http://math.ucr.edu/home/baez/temperature/ has a wide range of graphs showing temperature change since the start of the Pleistocene 3. Research details of the Pleistocene and pose questions for students to answer. When did it begin? What percentage of the Earth’s surface was covered by ice? How far south did the ice extend in Europe and in North America? When did it end? What was the effect on Britain? What happened in the highlands? What happened in the lowlands? How many advances and retreats of ice took place? What occurred during the interglacial periods (including animal life)? What might have caused temperatures to drop at the start of the ice age? What might have been the effect on sea levels and land levels? By how much did the temperatures drop? What evidence do we have for temperature changes? Produce maps to show the extent of ice over Britain and Europe. Annotate with details of ice sheets (e.g. Scandinavian), various limits, valley glaciation in the mountains, effects on sea level, direction of movement of ice etc 4. On the Web, students find the average winter and summer temperatures for their area and for Greenland. A good site to try is 2. Cloze type sentences with or without words provided e.g. During the Pleistocene era of the Quaternary, there were fluctuations in ____________ of 5° to 6°. These fluctuations led to cold phases ( ____________) and warm phases (______________). When the ice reached its maximum extent, it covered about ____ of the earth’s land surface. icebergs, and the effects that glaciation has had on the landscape 5. What is an ice age? When have ice ages occurred, and what has caused them to take place? (Ice ages are periods of time when large areas of Earth’s surface were covered with ice sheets. The term Ice Age refers to the last major glaciation that occurred in North America and Eurasia, from 2 million to 11,500 years ago, during the Pleistocene period. The movement of Earth’s plates, reduction of carbon dioxide in the atmosphere, and changes in Earth’s orbit are three major causes of ice ages.) 6. What happens to sea levels when glaciers melt and water runs into the sea? Students discuss how high they think sea-level could rise if different bodies of ice were to melt 7. How much of Britain was covered with ice during the last Ice Age? Research this on the internet and then draw your own line on a map of the UK showing the maximum extent of the ice. 8. Using maps of global ice coverage 20000 years ago and today, compare the distribution of ice on the earth’s surface. What are 2 sources of evidence that show changes in global temperature? 9. Show a picture of crevasses. Imagine what it would be like being lowered into a crevasse in a glacier. Think of 8 words which sum up what it would be like. Show a scene from “Touching the void” to illustrate. There http://www.wrh.noaa.gov/psr/general/monsoon/. How do they compare? How have Greenland's temperatures changed over the last decade? Students predict what might happen to the Greenland continental ice sheet if average temperatures continue to rise the way they have over the past decade—a summer temperature increase of 1.5-2 degrees Celsius and a winter temperature increase of 6 degrees Celsius. Ask students how they think the continental ice sheet might respond to these changes. 5. Construct time lines and associated maps, using coloured overlays to show extent of ice at different times. Include UK and Europe maps at height of ice advance, comparing with present day This can be linked to graphs / photographs / ice core evidence The point above which snow lies all year is known as the __________ __________ . Once snow has laid for some time, the weight of the top layers causes the lower layers to form ___________ . It takes at least _________ years for glacier ice to form. Glaciers are usually formed on _____________ slopes. The process of glacier ice melting is known as _______________. The difference between the rate of melting & the rate of accumulation is known as the ____ ________ . 3. Give students a scenario – e.g. "The world's temperature has increased by 6oC" “glaciers in the Alps completely melt” or "We start to enter a new ice age". Students have to come up with two pluses, two minuses, and two interesting things that might arise as a result of that situation 4. Show these images of the Himalayas mountains http://www.bbc.co.uk/learningzone/clips/th e-mountains-and-glaciers-of-thehimalayas/10565.html and these images of the melting of Arctic ice: http://www.bbc.co.uk/learningzone/clips/ar ctic-sea-ice-melts/10476.html are several trailers and clips http://www.touchingthevoid.co.uk/ at 10. http://www.museum.state.il.us/exhibits/ ice_ages/index.html Illinois State Museum presents information about the North American continental glaciers. They provide answers to the following questions: What are Ice Ages?, When did Ice Ages occur?, and Why do Ice Ages occur? 11. Use some of the statistics and facts at http://www.geographysite.co.uk/pages/physical/glaciers/facts .html as a general introduction to glaciation. The amount of ice depends on the glacial budget. This has seen a loss since 1950 and there are seasonal changes due to fluctuations in temperatur e.(R/L) Glacial budget: accumulation and ablation, advance and retreat.

Brainstorm ideas as to how a glacier might form. Write statements a-f (below) on the board. (The sequence is intentionally incorrect.) Put the statements into the proper order. a. The residual snow settles, becoming more compact and dense. b. The great weight of the top layers compacts the deep layers. c. Snow falls. d. Annual snow accumulation far exceeds the annual snowmelt. e. Compacted snow freezes together and creates sheets of ice. f. The number of layers increases. The correct sequence is: C, D, A, F, B, E.) 2. True false quiz e.g. (If you think it is false put the correct answer next to it.) Today, glacial ice covers about 20% of the Earth's land surface. In the past ice sheets probably covered about 30% of the Earth's land surface Smaller glaciers can be found at high altitudes in various mountain ranges in the lower, middle, and higher latitudes e.g. Mont Blanc, Canadian Rockies and The Alps. All glaciers move slowly uphill. The highest part, where the snow falls and turns to ice, is called the ablation zone. It is extremely cold in the accumulation zone, lots of snow falls and the temperature rarely rises above freezing. As the glacier moves downhill in starts to 3.Read this article which describes the changes in one glacier, Jakobshavn in Greenland, http://researchnews.osu.edu/archive/greenice.htm.

Use the resources available at http://www.discoveringthearctic.org.uk/ 6_climate_change.html to focus on threats to glacier ice and longer term http://www.pbs.org/wgbh/nova/sciencenow/3210/03.html In this 5.23.05 dispatch, watch a video clip and slide show about the NOVA scienceNOW expedition to Greenland's Jakobshavn glacier http://www.pbs.org/wgbh/nova/sciencenow/3210/nnvideo.html. Describe the changes in the size and features of the glacier. Discuss the causes of retreat. What is the evidence for change? What are the likely implications of these changes? (The glacier is moving faster and thinning more than expected. From 2000 to 2005, the glacier's speed increased dramatically— instead of moving one foot per day, which is normal for a glacier, the speed of the Jakobshavn Isbrae glacier has increased to an astounding 40 metres per day, and no one knows why. Compared to a decade ago, average temperatures in Greenland have increased 2ºC during the summer and 6ºC during the winter, leading to 60 percent more annual glacial melting). 4. Show this slide presentation about glacial budgets. http://www.slideshare.net/tudorgeog/l2-glacial-budget and refer to http://itc.gsw.edu/faculty/bcarter/physgeol/glac/budget.ht m then pose these questions: Explain the term ablation. On which part of a glacier does most ablation occur? Explain how the glacial budget affects whether a glacier is advancing or retreating. Describe and explain how you would expect the length of a glacier to change over a one year period. Explain the causes of retreat of glaciers over the past 100 years and the evidence for it. 5.

The place where the glacier melts is known as the accumulation zone. A snowflake can spend up to 20 years in a glacier before it melts. Wales has never been glaciated. Scotland has been glaciated. 3.Articulate Divide the class into 2 teams. Give one person from each team a handful of key terms relating to glaciation. The first team has 2 minutes to describe as many terms as they can without saying the word itself, their team has to guess the words correctly and they can only have 1 pass. It is then the turn of the other group. The winning group is the group which guessed the most terms correctly 4.Quick quiz Answer these questions: a. What conditions must exist for a glacier to form? b. How does snow change into glacial ice? c. What conditions are needed before a glacier will start to move? d. What is meant by Zones of accumulation and ablation, and how do these zones control the apparent movement of the glacier ? e. What are crevasses, and how do they form? 5. Show a series of images of a single glacier e.g. Mer de Glace at http://www.geographysite.co.uk/pages/physical/glaciers/tour.ht ml Enlarge the images and classify the landforms shown. What is happening to the length of this glacier? What implications does this have for the local community? What are the environmental implications? Describe the landscape features climatic change Ice is a powerful force in shaping the land as a result of weathering , erosion, transportati on and deposition. (R/L) Freeze thaw weathering. Processes of erosion – abrasion and plucking. Processes of movement and transportation – rotational slip and bulldozing. Deposition and the reasons for it. 1.http://www.bbc.co.uk/schools/gcsebit esize/geography/glaciation/glacialproc esses_video.shtml includes a simple introduction to processes What is the difference between weathering and erosion? Study the images on this website to show the effects of weathering and erosion http://www.swisseduc.ch/glaciers/earth _icy_planet/glaciers10-en.html 2. This site provides the sounds associated with ice moving www.antarctica2000.net/sounds/other. html 3. This youtube video shows the power of ice http://www.youtube.com/watch?v=cIBF Ake90SI&feature=player_embedded 4. Use the powerpoint presentations, worksheets and video clips at http://www.ngflcymru.org.uk/vtc/ngfl/geography/riv_gl ac/glaciation/index.html as starters to this key idea as well as other topics 5. There are several movies still available at the “Geography at the movies” site, although some have been removed for copyright reasons. The glaciation films appear under the rocks category at http://www.gatm.org.uk/geographyatth emovies/rocks.html Some excellent starters for this key idea and the next one 1. Students draw annotated diagrams to show and explain the processes of freeze thaw. Animations at www.geography.ndo.co.uk/weathering5.htm and www.yenka.com/freecontent/ attachment.action?quick=131&att=2799 2. Link process to definition. Start by asking questions about each process of erosion e.g. Which process is most likely in a hollow depression on mountain side? Which process is likely on steep valley sides where temperature fluctuates around 0oC? Which type occurs where steepening bedrock over which glacier is moving? Which type of erosion takes place due to the material acting like sandpaper? Which one relies on previously loosened material? Then match process to definition. Frost shattering – freeze-thaw produces loose material that may fall from valley sides. Abrasion – material trapped in glacier moves along and like sand paper smooths the rock. Plucking – glacier freezes on to rock and ice movement pulls away mass of rock. As bedrock has got greater strength than ice generally only previously loosened material. Rotational movement – downhill movement of ice, like a landslide, pivots about a point 3.Draw labelled diagrams to show how each of the following processes operates: freeze thaw weathering; plucking; abrasion Alternatively students produce powerpoint presentations or animated films to show each of these processes 4. Rearrange statements about the freeze thaw process into the correct sequence e.g. During the day, whilst the sun is shining, rocks, hollows and other weaknesses get wet or filled with water as glacial ice melts and soaks the rocks. At night the temperatures become colder and the water in the cracks freezes. As the water freezes it expands and causes the 1. Picture Reveal Template can be downloaded at: http://www.mediafire.com/?1jzyjzemte Pupils take it in turns to answer questions and get to reveal a piece of the picture if they are correct. 2. Revise the processes of glaciation and take a short test to assess understanding at http://www.bbc.co.uk/scotland/learning/bit esize/standard/geography/glaciation/proc esses_rev1.shtml 3. Wrong and Right statements – related to weathering and erosion processes e.g. freeze thaw is a type of erosion, materials transported by ice tend to be angular in shape, plucking smooths the rock by the scratching and scraping of material trapped in the glacier Teacher reads out a statement. If a true statement – pupils put up the right hand, if wrong – put up left hand. 4. Odd One Out from a group of three. Two marks. One for the correct odd one out and the second for the correct reason. E.g. freeze thaw, plucking, abrasion.....rotational slip, moraine, bulldozing.... cracks to widen. The next time the temperature is warm enough for the ice to melt, the water thaws and contracts. This cycle continues, each time widening or enlarging the cracks and hollows but a tiny amount. Eventually this continuous process causes rocks to break up. 5. Research how glaciers erode e.g. http://www.geographysite.co.uk/pages/physical/glaciers/erode.html then answer these questions 1. What is Freeze-Thaw? 2. What is Plucking, and whereabouts could it occur in a glacier? 3. What is abrasion and why is it an important cause of glacial erosion? 4. What are the main sources of rock debris found on, in and under a glacier? 5. What role do crevasses play in the erosional process? 6. The surface of a glacier is often littered with rock debris of all shapes and sizes. In a river you might expect some of this material to become rounded as it moves downstream, but in a glacier most of the material is rough and angular. Why do you think that the surface debris is both angular and of such a wide range of sizes 7. How do you think you might be able to differentiate between sediments transported by water over short and long distances, and material transported only by the glacial ice? What evidence would you look for in terms of particle size, sorting and roundness? Distinctive landforms result from different processes. (R/L) Landforms resulting from erosion – characteristics and formation of corries, arêtes, 1.

The second student then draws what is described onto paper 5. 10 Questions Pupils sit at the front facing away from the IWB. They must ask 10 YES or NO questions to find out what the picture/clue/keyword etc on the screen is. 6. Map from Memory Pupils work in groups of 4-6. Pupils each have 20 seconds to study a map or diagram of a glacial landform and go in the formation of each feature, and the sequence of formation. Devise a display board for each of the landforms: corries, arêtes, pyramidal peaks, troughs, truncated spurs, hanging valleys and ribbon lakes. They select a glaciated region and collect photographs, maps and aerial photographs of the region.

The clip would fit in well with a mapping exercise on the Lochaber area. (identification of landforms) 5. Sequencing task to describe the formation of a corrie (or glacial trough)-statements given on separate sheets ,students place in correct order e.g. snow collects in a sheltered hollow on the NE side of a mountain.......it turns to ice and then begins to move downhill, pulled by gravity....as it moves it curves or rotates (rotational slip)....material in the hollow is loosened by freeze thaw weathering, and moving ice plucks and abrades the material away from the sides of the hollow..the hollow becomes wider and deeper as erosion processes continue...most material is eroded from the back wall, which becomes very steep. Less is eroded at the front, so a lip forms here...when the ice melts, a lake or tarn may form in the hollow behind the lip. 6. Show this powerpoint presentation about glacial landforms.

Connect 4 Have a grid on the IWB and a list of questions. Divide the class into a red and yellow team. The teams take it in turns to choose numbers that correspond to your questions. First team to connect 4 in a row (column or diagonally), by answering the questions correctly, wins Continuum or Opinion Line 2. Have students stand somewhere along an "opinion line" (from front to back of classroom) showing how much they agree with a given statement, e.g.. "The Alps (or Himalayas) resources should be exploited to the full". Also works well with statistics, e.g. "What % of the world’s fresh water reserves are held as ice?" - 0% at the front, 100% at the back 3. Argument Tunnel This is a useful way to get everybody hazards. resorts for tourists? What activities would you like to do? What possible problems do the large number of visitors bring to areas such as the Alps? 5. What is an avalanche? Why is it such a dangerous hazard? Which areas are most at risk? What factors make the risk greater? Why have more people been killed in avalanches in recent years? What time of year is worst for avalanches? Why is this? What can be done to protect people? How long would you survive if you were trapped in an avalanche? What types of avalanches are there? (loose snow, slab) See p 141-143 in the Nelson Thornes text 6. This short film examines the causes of avalanches http://www.youtube.com/watch?v=B0R WLxOFGLY&feature=player_embedde d and this looks at the factors involved http://www.youtube.com/watch?v=wcr1 Sl-T9S0&feature=player_embedded 7.

Design a tourist brochure about the French or Swiss Alps and include information about the glacial features in the area. Include diagrams and sketches. Research the range of tourist activities available including summer activities. Use a map extract to plan a touring holiday in which the visitors stop off at various points and do short walks and visit various features. Ask students to draw up a table listing the advantages and disadvantages that tourism brings to glaciated areas 4. Conflict matrices to show various interest groups e.g skiers / sightseers / local guides / local businesses / conservationists with conflict scored or simply noted and commented upon 5. Read the information about tourism in the French Alps in the Nelson Thornes text pages 135 -137. Prepare a fact file about Chamonix, to include the following details: Location, population, tourist attractions in winter, attractions in summer, advantages of tourism to the Chamonix area, environmental problems caused, social problems, economic problems, conflicts, management measures to protect the environment, measures to protect the economy. Refer also to www.chamonix.com 6. Pose a number of issues relating to avalanches as hazards e.g. Who gets caught in avalanches? When and where avalanches happen. Avalanche types. Avalanche factors: What conditions cause an avalanche? Avalanche gear. Tips for avalanche survival. Avalanche danger scale. Use http://nsidc.org/snow/avalanche/ for background information. Look also at the Scottish avalanche information service site at http://www.sais.gov.uk/aboutavalanches.asp 7. Produce a safety guide for people visiting areas with a high avalanche risk See http://environment.nationalgeographic.com/environment/ natural-disasters/avalanche-safety-tips/ for ideas involved in expressing opinions and looking at different values and attitudes. Get the students into 2 lines facing each other, have a topic that you wish to discuss e.g. developing Alpine area for tourism. One side will be arguing for the idea, the other side against. They have about a minute to ‘argue’ their points with the person opposite then move 1 side up 1 place so that they can ‘argue’ with another person. At the end you can have a game of argument tennis where you choose three people, two of whom take it in turns to make their points and respond to the other persons points, the third person scores the argument by awarding the person who makes the best point with tennis score (15 love etc) 4. Show this video which illustrates how some areas can be protected from avalanches http://www.bbc.co.uk/learningzone/clips/lif e-in-the-pyrenees-mountainsroads/8426.html 5. Students are divided into groups and recap the main features of their case study e.g. Chamonix. Subdivide into different aspects studied e.g. Tourism in the French Alps - Winter attractions - Summer attractions Impacts of tourism in the French Alps - Benefits of tourism - Problems of tourism Managing tourism in Chamonix 6.

Students watch the Channel 4 clip Avalanche conditions in Galtür and/or use this site to obtain information http://schoolswikipedia.org/wp/a/Avalanche.htm . They then use a worksheet to arrange the causes of the avalanche, as mentioned in the two clips from long to short term causes. Students can also decide which, if any, can be seen as the trigger. Discuss the answers as a class. Use the discussion as an opportunity to explore how the causes are linked - for example - are low pressure and low temperatures connected? Explore understanding of long term and short term and encourage students to explain their thinking where there are disagreements for example - can gravity seen as the longest term cause, as it has existed the longest, or as the trigger, as it triggered the built up snow to finally travel down the mountain? Students then read an exam-style mark scheme for the question What caused the Galtür avalanche in 1999? Discuss their understanding as a class and ask students which aspects they, personally, may find the most challenging. Students then use the mark scheme, and their work on the long term/short term scale, to answer the question aiming for full marks. 9 .http://www.pbs.org/wgbh/nova/teachers/activities/2418_ avalanch.html has a classroom activity which investigates the complexities of snowpack formation and shows how avalanches occur. See also http://www.ur.co.nz/avalanche/experiment.htm To support this activity, there are 6 video clips of avalanches at http://www.pbs.org/wgbh/nova/avalanche/capture.html and the experiment is shown at http://www.bbc.co.uk/learningzone/clips/avalanches/108 58.html Glacial retreat can pose a threat to the economies The impact of retreat and unreliability of snowfall in some resorts.

This article considers the future of the skiing industry. http://www.geographyteachingtoday.org.uk/images/text/ KS3_Glaciation_3MeltingMountains.pdf Why is skiing so important to people and places in the Alps? Why is skiing in the Alps under threat? 1. Show this video as a summary of the changes taking place in glacial environments http://www.pbs.org/wgbh/nova/scienceno w/video/3210/w03-220.html of areas relying on tourism and result in damage to fragile environme nts.(R/L) social and environmental impact – including the concept of fragile environments. 2. This interactive game considers threats to fragile environments http://www.discoveringthearctic.org.uk/ swf/6_boardgame/6_climate_challenge .html 3. Explain what is meant by fragile environment, environmental impact and management strategy 4. Print off examples of newspaper reports which highlight threats to alpine resorts e.g. Daily Telegraph http://www.telegraph.co.uk/earth/earth news/3342553/Climate-change-threatto-alpine-ski-resorts.html New York Times http://www.nytimes.com/2006/12/16/w orld/europe/16austria.html?_r=1 Daily Mail http://www.dailymail.co.uk/news/article -12104/Ski-resorts-face-globalwarming-threat.html http://www.thisisdevon.co.uk/news/We st-scientists-ski-resorts-Alps-riskextreme-flooding/article-2300778detail/article.html Ask students to highlight any factual evidence of climate change mentioned, then consider the effects of retreating glaciers. Make a list of the likely consequences 5. Show the pictures of retreating glaciers found at this site http://www.worldviewofglobalwarming. org/pages/glaciers.html Compare the “then” and “now” images and state how far some of the glaciers have retreated 2. Imagine that you are work in the tourist industry in the Alps. Because skiing is under threat, you will have to think of another way to attract visitors to the Alps. Write a list of all of your ideas. Now, in groups of four, pick the best idea and design a leaflet, poster or advertising campaign that could be used to attract a new type of tourist to the Alps. 3. What consequences might the change in glaciation have for human economic activity and the tourism industry? Many places in the European Alps and elsewhere depend on their nearby glaciers as a primary resource for tourism and recreation. The following websites show what may happen to particular valleys in Switzerland as a result of changes to the volume of ice in the glacier; http://www.sp.uconn.edu/~geo101vc/Lecture2/sld012.ht m Here is a model from North America. http://nrmsc.usgs.gov/research/glacier_model.htm What consequences might this have for a range of economic activities in this area? 4. Study the information on p138-139 in the Nelson Thornes text about the impact of climate change on the Alps. What is the evidence for climate change ? What effects has this had on the lower level resorts in the Alps? What have been some of the responses to glacial retreat in the lower level resorts? What problems may occur if the higher level wilderness areas are developed for tourism? 2. Show me the links! Pupils to write down on a blank piece of A4 everything they can remember about glaciation. This can be done as a group activity on the board. After 5 minutes of brainstorming pupils join up words that are linked. They can also give reasons why they are linked 3. Use the http://classtools.net/ by Russel Tarr in lessons. From tools for giving pupils time limits on tasks using the countdown timer, to using the Venn diagram tool get pupils to identify the economic, social and environmental impacts of an issue such as retreating ice. 4. Ask students to create a 30 second soundbite for a local radio programme on the future of the Alps (or the Cairngorms). Different students take on roles of people with different views. 5. Predictions about the future include the fact that “Up to 75% of alpine glaciers will disappear within the next 50 years” Ask students to discuss the implications of this – e.g. greater risk of avalanches, more flooding, closure of all ski resorts below 2000m, more soil erosion, unemployment, diversification of tourist activities, more summer tourism etc 6. Show this video depicting melting glaciers in the Himalayas, including those emanating from Mt Everest http://www.neok12.com/php/watch.php?v =zX457c067c60500a41185d7f&t=Glacier s What has been the rate of retreat recently?
