Quality of Written Communication will be assessed in this answer.
1.
Describe the methods used to reduce the problem of ozone depletion. (Jan 10)
2. Describe the likely consequences of global climate change on the survival and distribution of wildlife
(June 10)
3. Describe the main processes that have produced deposits of minerals and rocks that may be exploited
by humans. (Jan 11)
4. Describe the ways that global climate change is likely to cause changes in weather patterns and ocean
currents. (June 11)
5. Explain how the human control of biogeochemical cycles provides many benefits to humans but also
creates environmental problems. (Jan 12)
6. Describe the advantages and disadvantages of exploiting the different sources of water that may be
available for public supply. (June 12)
7. Describe how global climate change is likely to affect the survival of wildlife. (Jan 13)
8. Describe the ways in which positive and negative feedback mechanisms may alter the processes of
global climate change. (June 13)
9. How can farmers use knowledge of biogeochemical cycles and soil properties to maintain soil fertility?
(specimen)
Made up ones:
1.
Discuss the factors considered when siting dams and reservoirs.
2. Describe the stages in and account for the methods used to purify water from different sources.
3. Compare and contrast the processes that cycle Nitrogen and Phosphorous between the ‘reservoirs’.
4. Outline the tests that can be applied to soils when testing for agricultural value and state what
properties a soil of high agricultural value would have.
5. Explain the stages in mechanised mining for metals and coal, and discuss how increased mechanisation
can cause the potential amount of an ore that can be mined to change?
6. Describe and explain the appropriate techniques used when prospecting for different mineral ores
(both metals and hydrocarbons).
7. Explain the main processes that regulated the gases in the atmosphere.
8. Explain the consequences of global climate change on wind and rainfall patterns as well as ocean
currents.
9. Evaluate the usefulness of the strategies used to manage climate change.
10. Explain the main criteria used when assessing water quality.
11. Explain why land-use conflicts arise associated with the use of a water resource and discuss the
strategies that can be used to resolve them.
12. Using one or more case studies explain the consequences of over abstraction on water supply.
13. Explain the factors that control the viability of mineral extraction (both the physical or geological and
economic)
14. Explain how the environmental impacts of mining can be reduced and explain how the future of metal
ores can be ensured.
Legacy
1.
The best agricultural land will be used for food production, Outline the soil properties that will be
useful for soil fertility.
2. Describe how plants and animals are likely to be affected by climate change.
3. Describe the Environmental Impacts of mineral extraction.
4. Describe how nitrogen is cycled between the gaseous, hydrological, sedimentary and biological
reservoirs. (do this too for the carbon cycle)
5. Describe the processes that are used to treat sewage to prevent pollution.
6. Outline how different industries have different quality requirements for water.
7. Describe the properties of a fertile soil.
