Lesson Details
Key learning points
- Natural processes that happen at the coast help to shape coastlines.
- There are four types of erosion: abrasion, hydraulic action, attrition and solution.
- There are four types of transportation: traction, solution, suspension and saltation.
- The process of deposition occurs when waves have lost their energy and can no longer carry their load.
Common misconception
Students frequently mix up the different types of processes, their names and definitions.
Flag up words for processes that sound similar or have similar spellings as you encounter them. Signpost the differences in their meanings, and encourage students to highlight them in a way that is most useful for them, for example by colour coding.
Keywords
Process - A process is an ordered series of actions, events or changes that make something happen.
Erosion - Erosion is the process of Earth’s surface, e.g. rock or soil, being worn away and transported from its original site.
