Learning Objective
Students will identify the agents of erosion and explain how each moves and shapes Earth’s surface
- 1
Weathering is the breakdown of rocks into sediments, while erosion is the transportation of those sediments by wind, water, or ice.
- 2
Physical weathering breaks down rocks without changing their composition, whereas chemical weathering changes the rock's chemical makeup through processes like oxidation.
- 3
Deposition occurs when sediments are dropped in a new location by water, ice, or wind, creating formations like deltas and sand dunes.
