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 explain the processes of river erosion, transportation and deposition.
Key Notes
- There are four types of erosion: abrasion, hydraulic action, attrition and solution.
- There are four types of transportation: traction, solution, suspension and saltation.
- Deposition occurs when the river has lost its energy and can no longer carry its load.
Vocabulary To Learn
- erosion: the process by which Earth's surface, e.g. rock or soil, is worn away and transported from its ordinal state and original location
- transportation: where rivers move sand, mud and rocks
- deposition: when sand, mud and rocks are dropped by the river
Common Mistakes To Avoid
- Attrition is where rocks and sediment carried by the river collide with the bed and the banks causing pieces to break off.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
There are four types of erosion: abrasion, hydraulic action, attrition and solution. There are four types of transportation: traction, solution, suspension and saltation.
2. Define this geography term and use it in an example. 'erosion'
the process by which Earth's surface, e.g. rock or soil, is worn away and transported from its ordinal state and original location.
3. Correct this common geography misunderstanding.
Mistake: Attrition is where rocks and sediment carried by the river collide with the bed and the banks causing pieces to break off. Correction: Abrasion is where rocks and sediment carried by the river collide with the bed and the banks causing pieces to break off.
