Weathering, Erosion, and 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 movement of sediment or soil from one location to another by means of water, ice, or wind.

Front

What is Deposition?

Back

Deposition is when particles carried by water, ice, or wind are deposited in another location, creating new landforms.

Front

How does Weathering occur?

Back

Weathering can occur through physical processes (like freezing and thawing) or chemical processes (like acid rain dissolving rocks).

Front

What is an example of Erosion?

Back

An example of erosion is a river carrying away soil and rocks as it flows.

Front

What is an example of Deposition?

Back

An example of deposition is sand being dropped by wind to form dunes.

Front

What role does water play in Weathering?

Back

Water can cause weathering by freezing in cracks of rocks, expanding, and breaking them apart.

Front

What is the difference between Weathering and Erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

What is Chemical Weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, such as when acid rain dissolves limestone.

Front

What is Physical Weathering?

Back

Physical weathering involves the mechanical breakdown of rocks without changing their chemical composition, like ice wedging.
