Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as water, ice, and wind.

Front

What is erosion?

Back

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

Front

How does freezing water contribute to weathering?

Back

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

Front

What role does wind play in weathering?

Back

Wind can blast sand and other particles against rocks, wearing them down and creating features like arches.

Front

What is the relationship between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water freezes in rock cracks and expands, causing the rock to break.

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 deposition?

Back

Deposition is the process where sediment is laid down in new locations after being transported by erosion.

Front

How do glaciers contribute to erosion?

Back

Glaciers can move large amounts of rock and sediment as they advance and retreat, shaping the landscape.

Front

What is the impact of weathering on soil formation?

Back

Weathering breaks down rocks into smaller particles, which contribute to the formation of soil.
