Student Centered Objectives
I will understand how certain landforms are created
I will know how maps are used to understand the size and shape of the Earth, it’s surface and interior

Landforms & Forces
• Landforms can be created by constructive processes, such as deposition. These landforms include deltas, barrier islands, and sand dunes. Landforms can also be created by destructive processes, such as erosion. These landforms include valleys, canyons, caves, arches, and lakes.
WHAT COULD BE MORE SOLID THAN MOUNTAINS?
Valleys, Canyons, Caves and Arches
Lakes, Valleys & Glaciers
• Erosion can create new landforms such as valleys, canyons, caves and arches. Erosion is the process by which rock and soil are moved by wind or moving water.
Deltas and Sand Dunes
• The process of deposition involves the movement of sediment from one area to another and can create new landforms such as river deltas, barrier islands, and sand dunes.
• Strong winds can cause sand on beaches to move to new areas and form large mounds, called sand dunes. • Also, flowing water can pick up sediment from its banks and carry it downstream. Near the place where a river empties into the ocean, the water flow becomes very slow. The slow‐
moving water lays down the rest of the sediment it is carrying. A new landform is created from the sediment. This landform is called a delta. (See Google Earth)
Barrier Islands
• A narrow island running
parallel to the coast built up
by the action of waves and currents

Quiz time
• What causes erosion?
•
•
•
•
A. Wind
B. Water
C. Ice
D. All of the above
Rise of Mountain Ranges
• Occurs over time where two
continental plates collide and begin their slow push upwards.
Quiz Time
• Did you get D ?
• Correct answer is water, wind and ice all cause erosion
Images and Maps used to study the Earth
• Imagery‐ cameras attached to aircraft that take pictures of the surface of the Earth below; bird’s eye view
(Google Earth) Satellite Images
• Can cover a large portion of the Earth • Uses different kinds of radiation to provide different views of the Earth’s surface
• Scientists can learn more about the geologic features
Maps
• Globe
• Topographic map‐ uses contour lines to show elevation
– Contour interval‐ the change in elevation between two lines beside each other
– Relief is the difference between the highest point on the map and the lowest point

Spheres of the Earth
Relief Map • Atmosphere‐ composed of thin layer of gases that surround the Earth.
– Water vapor is always present and has a powerful effect on the weather
– Plays an important role in warming the Earth and sustaining plant and animal life
http://video.about.com/geography/The‐Four‐Earth‐Spheres.htm
Spheres of the Earth
• Biosphere‐ any part of the Earth where organisms live. Extends from the crust to the atmosphere
• Geosphere‐ the physical elements of the Earth’s surface, crust and interior
– Continental Drift, earthquakes and volcanoes
• Lithosphere‐ outermost layer of the Geosphere
Spheres of the Earth
• Hydrosphere‐ all of the water on or near the surface of the Earth
– Water vapor in clouds, solid water in ice caps and glaciers and liquid water in oceans, lakes and ponds.
• Cryosphere‐ the frozen portion of the hydrosphere
The Earth System
Quiz time
• Which of the spheres of the Earth would contain life?
•
•
•
•
A. Atmosphere
B. Biosphere
C. Lithosphere
D. All of the above

Quiz time
Nitrogen Cycle
• All of the above contain some sort of life even if it is in the micro‐organism form but the correct answer is B. Biosphere. • Nitrogen has to be converted to a usable form to be used (nitrates)
• The Atmosphere is the air, the Lithosphere is the ground and the Biosphere is everything in‐
between.
• Consumers use the nitrogen from the organisms they consume
• Nitrogen is returned to the atmosphere
– Nitrogen‐fixing micro‐
organisms
• Nitrogen has to be
Greenhouse Effect
• On a warm sunny day you come back to your locked up car. What is it like inside the car? It is boiling hot — much hotter than outside. Why is that?
Carbon Cycle Game
Carbon Cycle
• The Earth’s atmosphere contains carbon dioxide, methane and water vapor. Greenhouse gases.
• These trap the sun’s energy and keep our planet warm
• The carbon is recycled in our atmosphere naturally
• The problem arises when there is too much carbon in the atmosphere and it is not being recycled fast enough

QUESTIONS / DISCUSSION
If you have a question raise your hand. Next use the polling tool If you have a working microphone and you have done the audio set up give me a green check. If not then give me a red x. People with a red x can type their question in the chat box but don’t send it until it is your turn.
