Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process where soil and rock are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

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

Front

Give an example of weathering.

Back

An example of weathering is when rainwater seeps into cracks in rocks and freezes, causing the rocks to break apart.

Front

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include water, wind, and ice.

Front

How does a mudslide relate to erosion?

Back

A mudslide is an example of erosion because it involves the movement of soil and rock down a slope.

Front

What role does water play in weathering?

Back

Water can cause weathering by dissolving minerals in rocks and by freezing and thawing, which breaks rocks apart.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one place to another.

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops sand and silt at its mouth, forming a delta.

Front

How can plants affect erosion?

Back

Plants can help prevent erosion by holding soil in place with their roots.
