Exam-style question
Try this first
Evaluate the impact of deforestation on the water cycle in tropical regions.
Model answer
What a good answer should say
- Deforestation disrupts the water cycle by reducing transpiration, which decreases local humidity and rainfall.
- This can lead to drier conditions and affect local ecosystems.
- Additionally, the removal of trees increases runoff and soil erosion, further altering the water cycle dynamics.
Explanation
