What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, often involving water and acids, changing the mineral composition of the rocks.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks down rocks into smaller pieces without changing their chemical composition, often through mechanical forces like freeze-thaw cycles.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring when the energy of the transporting medium decreases.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water like an ocean or lake.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical (physical) weathering and chemical weathering.

Front

What role does acid rain play in weathering?

Back

Acid rain contributes to chemical weathering by reacting with minerals in rocks, leading to their breakdown.

Front

How does freeze-thaw action contribute to physical weathering?

Back

Freeze-thaw action contributes to physical weathering by causing water to freeze in cracks of rocks, expand, and eventually break the rocks apart.

Front

What is an example of erosion caused by water?

Back

An example of erosion caused by water is the wearing away of riverbanks during heavy rainfall or flooding.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks in place, while erosion involves the movement of those broken materials from one location to another.
