Weathering, Erosion, Deposition

Front

What is Weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is Erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

What is Deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of rivers or in lakes.

Example of Weathering:

Back

Water gets into cracks in rocks, freezes, and expands, causing the rocks to break apart.

What role does water play in Weathering?

Back

Water can cause weathering by freezing in cracks of rocks, leading to expansion and breaking the rocks apart.

How does Erosion change landscapes?

Back

Erosion can create valleys, canyons, and other landforms by removing soil and rock from one area and depositing it in another.

What is the difference between Weathering and Erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a different location.

What is an example of physical weathering?

Back

Physical weathering can occur when rocks are broken down by temperature changes, such as freeze-thaw cycles.
