Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the natural chemical or physical process that breaks down rocks on Earth's surface.

Front

What is erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves weathered rock and soil from one place to another.

Front

What is deposition?

Back

Deposition occurs when eroded materials stop moving and begin to build up.

Front

How does freezing water cause the weathering of rocks?

Back

Freezing water expands cracks and breaks rocks.

Front

What is the main effect of weathering?

Back

The main effect of weathering is the breaking down of rocks.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical weathering and chemical weathering.

Front

Give an example of physical weathering.

Back

An example of physical weathering is the freezing and thawing of water in rock cracks.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to water or acids.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and soil down slopes, contributing to erosion.

Front

What is the difference between erosion and deposition?

Back

Erosion is the movement of materials, while deposition is the accumulation of materials in a new location.
