What is erosion?

Back

Erosion is the process of moving weathered rock and soil from one place to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process of dropping sediment in a new location after it has been transported by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to a new location.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when rocks are broken apart by freezing and thawing.
