Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking 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, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

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

What are the main types of weathering?

Back

The main types of weathering are physical weathering, chemical weathering, and biological weathering.

Front

Give an example of physical weathering.

Back

An example of physical weathering is the cracking of rocks due to freeze-thaw cycles.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away particles and shaping the landscape.

Front

What is an example of deposition?

Back

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

Front

How does wind contribute to erosion?

Back

Wind can pick up and carry small particles of soil and sand, eroding surfaces and reshaping landscapes.

Front

What is compaction?

Back

Compaction is the process where sediments are pressed together under pressure, often leading to the formation of sedimentary rocks.
