Weathering and Erosion

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the dropping off of sediments in a new place after they have been transported by erosion.

Front

How does freezing water cause weathering?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

What is a sediment?

Back

Sediment is small pieces of rock, soil, and organic material that are moved by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces to new locations.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freezing and thawing, as well as chemical reactions.

Front

What is a slow land change?

Back

A slow land change is a change that takes a long time, such as the gradual erosion of a mountain.

Front

What is an example of erosion?

Back

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

Front

How does deposition affect the landscape?

Back

Deposition can create new landforms, such as deltas and sandbars, by adding layers of sediment.
