Learning Objective
I can describe how weathering and erosion create different landforms.
- 1
Erosion is when the surface of the Earth wears away, often caused by water breaking down rock and dirt.
- 2
The ocean causes erosion through waves that break up rocks along the coast, forming landforms like cliffs, beaches, and sea stacks.
- 3
Glaciers, or rivers of ice, cause erosion by breaking off and scraping away pieces of rock and stone, creating landforms like valleys, lakes, and fjords.
