Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where sediments settle and accumulate in a new location after being transported by erosion.

Front

What is compaction?

Back

Compaction is the process where sediments are pressed together under pressure, reducing the space between them.

Front

Give an example of weathering.

Back

An example of weathering is rain breaking down rocks into smaller pieces.

Front

Give an example of erosion.

Back

An example of erosion is wind blowing away sediment to a new place.

Front

Give an example of deposition.

Back

An example of deposition is sand being deposited at the mouth of a river.

Front

What role does water play in weathering?

Back

Water can cause chemical weathering by reacting with minerals in rocks, leading to their breakdown.

Front

What is the difference between weathering and erosion?

Back

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

Front

How does vegetation affect erosion?

Back

Vegetation helps to reduce erosion by stabilizing the soil with roots and absorbing water.
