Human Impact on Drainage Basins

The video tutorial guides students through answering a 20 mark evaluate question from the AQA EAS paper, focusing on the water and carbon section. It explains the question structure, planning, and writing an effective answer using the 'pickle' acronym. The tutorial emphasizes understanding human impact on drainage basins, using examples like the River Brock, and evaluating potential future changes due to global warming.

What does the 'P' in the PICKLE acronym stand for?

• People

• Potential

• Process

• Place

Which component of the question focuses on knowledge and understanding?

• AO4

• AO2

• AO3

• AO1

What is the main focus of the question discussed in the video?

• Impact of human activity on biodiversity

• Urbanization

What is the potential future impact of global warming on river discharge?

• Decrease in river discharge

• No change in river discharge

• More predictable river discharge

• More extreme and unpredictable river discharge

What is the impact of afforestation on the drainage basin?

• Decreases water quality

• Decreases infiltration

• Increases surface runoff

• Increases infiltration and stem flow

What is the purpose of peat bog restoration in the context of the video?
