Weathering and Erosion

Front

What is weathering?

Back

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

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

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

Front

What is acid rain?

Back

Acid rain is precipitation that has a lower pH than normal, often caused by pollutants in the atmosphere, and can lead to chemical weathering of rocks.

Front

What is abrasion?

Back

Abrasion is the process of wearing down surfaces through friction, often caused by wind or water carrying particles that scrape against rocks.

Front

How does ice wedging cause weathering?

Back

Ice wedging occurs when water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart.

Front

What is deposition?

Back

Deposition is the process by which eroded materials are dropped in new locations, contributing to the formation of new landforms.

Front

What is the role of water in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away particles, and reshaping the landscape.

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 new locations.
