Weathering, Erosion, and Deposition

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 deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical (mechanical) weathering and chemical weathering.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking rocks into smaller pieces without changing their chemical composition, often through temperature changes, freezing, and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water, acids, or gases.

Front

What is an example of physical weathering?

Back

An example of physical weathering is freezing and thawing, where water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart.

Front

What is wave erosion?

Back

Wave erosion is the process of erosion caused by the action of ocean waves, which can wear away coastlines and create features like cliffs and beaches.

Front

What is wind erosion?

Back

Wind erosion is the process where strong winds blow away loose soil and sand, often leading to the formation of dunes.

Front

What is ice erosion?

Back

Ice erosion occurs when glaciers move and scrape away the land beneath them, transporting rocks and sediments.
