Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and other materials on Earth's surface.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands cracks and breaks rocks.

Front

What is erosion?

Back

Erosion is the movement of weathered rocks and soil by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where materials are dropped or settled in a new location, often forming new land features.

What natural force is largely responsible for the formation of the Grand Canyon?

Back

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

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the weathered materials.

Front

What role does wind play in erosion?

Back

Wind can carry small particles of sand and dust, eroding surfaces 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 leading to their breakdown.

Front

Give an example of biological weathering.

Back

Biological weathering occurs when plants grow in cracks of rocks, breaking them apart as they grow.
