Rivers: How do rivers shape the land?
Study Hub
Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit teaches pupils about how river processes shape the land and affect our lives. Pupils will use fieldwork to investigate downstream changes in rivers and use GIS to analyse flood risk across geographical space. Pupils will also evaluate different methods of flood management.
Lesson Summary
You will learn to describe the human and physical causes of river flooding.
Key Notes
- Floods occur when a river receives more water than the channel has capacity for.
- Heavy and prolonged rainfall are the main physical causes of flooding.
- Other physical causes of flooding are the shape and geology of the drainage basin.
- Deforestation and urbanisation are the main human causes of flooding.
Vocabulary To Learn
- prolonged rainfall: continuous rainfall that lasts for longer than expected
- relief: the physical shape of the land in an area, including its height and steepness
- geology: the physical structure of an area and what rocks and minerals exist there
- deforestation: the complete removal of trees from an area
- urbanisation: the increase in the proportion of people living in towns and cities rather than the countryside
Common Mistakes To Avoid
- Flooding is only caused by physical factors such as heavy rainfall.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Floods occur when a river receives more water than the channel has capacity for. Heavy and prolonged rainfall are the main physical causes of flooding.
2. Define this geography term and use it in an example. 'prolonged rainfall'
continuous rainfall that lasts for longer than expected.
3. Correct this common geography misunderstanding.
Mistake: Flooding is only caused by physical factors such as heavy rainfall. Correction: Human factors can lead to flooding too, such as deforestation.
