Weathering, Erosion, and Deposition

Front

What is weathering?

Back

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

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 water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the bottom of oceans or rivers.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands in cracks of rocks, causing them to break apart.

Front

What natural process formed the Grand Canyon?

Back

The Grand Canyon was formed primarily by erosion from the Colorado River over millions of years.

Front

What is the difference between weathering and erosion?

Back

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

Front

What role does wind play in erosion?

Back

Wind can carry small particles of soil and sand away, leading to erosion of the land.

Front

What is chemical weathering?

Back

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

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks into smaller pieces without changing their chemical composition, often due to temperature changes.

Front

Give an example of erosion caused by water.

Back

An example of erosion caused by water is a river cutting through rock to form a canyon.
