What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical structure of rocks, often through reactions with water, acids, or gases.

Front

What is erosion?

Back

Erosion is the process of moving sediments from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down or settled in a new location after being transported by erosion.

Front

What are the three types of wetlands?

Back

The three types of wetlands are swamps, marshes, and bogs.

Front

How does freezing contribute to physical weathering?

Back

Freezing causes water to expand in cracks of rocks, leading to the breaking apart of the rocks.

Front

What is the role of acid rain in weathering?

Back

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

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces to a new location.

Front

What is an example of a natural process that causes erosion?

Back

Rainfall can cause erosion by washing away soil and sediments into rivers and streams.
