What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

What is ice wedging?

Back

Ice wedging is a type of mechanical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to the formation of new materials.

Front

What is an example of mechanical weathering?

Back

How does freezing contribute to weathering?

Back

Freezing causes physical weathering by expanding water in cracks, which breaks the rock apart.

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one location to another by wind, water, or ice.
