Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one place to another, often caused by water, wind, or ice.

Front

How does freezing water cause weathering?

Back

Freezing water expands cracks in rocks, which can break the rocks apart.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform, often creating new features.

Front

What is the main cause of the Grand Canyon's formation?

Back

Water is largely responsible for the formation of the Grand Canyon through erosion.

Front

Are weathering and erosion the same thing?

Back

False, weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What is a slow land change?

Back

A slow land change is a change that takes a long time, such as the gradual erosion of a mountain.

Front

What role does wind play in erosion?

Back

Wind can carry small particles of sand and soil away, reshaping the landscape over time.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.

Front

What is chemical weathering?

Back

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