Learning Objective
I can describe how weathering, erosion, and deposition change the Earth’s surface.
- 1
Weathering is when rocks are broken down into smaller pieces by forces like water, wind, and ice.
- 2
Erosion is like nature's moving truck, transporting pieces of rock across landscapes by forces such as wind, rain, and ice.
- 3
Deposition occurs when pieces of rock and soil settle down in a new place, like how wind forms sand dunes in the desert.
