1 Rainforest Case study Qs: 1. Examine how physical and/or human factors affect the stores and flows of the carbon/water cycle in the tropical rainforest (10marks) 2. With reference to a drainage basin within a tropical rainforest, examine the changes to the flows and stores in the water cycle caused by natural and human factors. (10marks) 3. Examine the impact of human activity on carbon flows/soil/nutrient stores. (10marks) 4. Explain how management strategies to manage tropical rainforest have positive effects on the water and carbon cycles. (10marks) 5. Using a case study, assess the importance of rainforests trees in the water and carbon cycles. (16marks) 6. The impacts of human activity on tropical rainforests can be easily managed. With reference to a case study, to what extent do you agree with this statement? (16marks) 7. To what extent are human factors altering the water and carbon cycles in the tropical rainforest? (16marks)

2 Tundra case study Qs: 1. Examine how physical and/or human factors affect the stores and flows of the carbon/water cycle in the tundra (10marks) 2. Examine the impacts of human activity on the water and carbon cycles in the tundra. (10marks) 3. Explain how management strategies can moderate the effects of human activity on the tundra water and/or carbon cycles. (10marks) 4. Using a case study of the arctic tundra, assess the importance of permafrost in the water and carbon cycles. (16marks) Combined Amazon and tundra questions. 1. Examine the differences between the water and or carbon cycles in the tropical rainforest and tundra. (10marks) 2. Humans have a greater impact on the water/carbon cycles in the Rainforest than the tundra. To what extent do you agree with this view? (16mark) 3. Impacts on the carbon cycles can be more easily managed in the rainforest than the tundra, to what extent do you agree with this view? (16marks)

3 Human impacts and strategies Qs: 1. Examine how land use changes can alter the water and carbon cycles. (10marks) 2. Examine how water extraction can impact on the water/carbon cycles. (10marks) 3. Examine the impact of fossil fuel combustion on the carbon cycle. (10marks) 4. Examine the impact of human activities on the water/carbon cycle. (10-marks) 5. Examine how positive and negative feedback can impact the water/carbon cycles. (10marks) 6. Examine how the water cycle can change over time. (10marks) 7. Examine how the carbon cycle can change over time. (10marks) 8. Examine how the water and carbon cycles are linked. (10marks) 9. Examine the impact of long term climate change on the water/carbon cycles. (10marks)

4 10. Examine how global management strategies can protect the carbon/water cycle. (10marks) 11. Land use changes have more significant effects on the water cycle than the carbon cycle. To what extent do you agree with this view? (16marks) 12. To what extent are long term changes in the water/carbon cycle more significant than short term changes. (16marks) 13. To what extent are the water and carbon cycles linked? (16marks) 14. To what extent can global management strategies lessen the impact of long term changes in the water/carbon cycles 15. Changes in the water/carbon cycle will always lead to the system returning to a state of dynamic equilibrium. To what extent do you agree with this view. (16marks)
