Lesson details
Key learning points
- There are four types of erosion: abrasion, hydraulic action, attrition and solution.
- The geology of a coastline will have an impact on the rate of erosion.
- Coastal landforms, such as arches, are formed through erosional processes over millions of years.
- The sequence from a headland to a stump is: headland, cave, arch, stack, stump.
Keywords
Erosion - the process of Earth’s surface, e.g. rock or soil, being worn away and transported from its original site
Landform - landforms are natural features created by processes such as erosion or deposition
Geology - the geology of an area is its physical structure and the rocks and minerals that exist there
Rate - a measure of the quantity, frequency or speed at which something happens or occurs
Common misconception
Students may think that soft rock is physically soft to the touch, like a pillow.
Geologically soft is not the same as being soft like a pillow. All rock feels solid when touched, even soft rocks. Rock that is classified as soft, like clay, can crumble and break more easily than rock which is classified as hard, like granite.
