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