Weathering, Erosion and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces or sediments through physical or chemical means.

Front

What are the two types of weathering?

Back

The two types of weathering are chemical weathering and physical weathering.

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 geological process where sediments, soil, and rocks are added to a landform or land mass.

Front

How does wind contribute to weathering?

Back

Wind can carry sand and other particles that blast against rocks, causing them to break down, a process known as weathering.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away sediments and reshaping landscapes.

Front

Give an example of physical weathering.

Back

An example of physical weathering is the freeze-thaw cycle, where water enters cracks in rocks, freezes, expands, and eventually breaks the rock apart.

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

How does deposition occur in rivers?

Back

Deposition in rivers occurs when the water slows down, causing sediments to settle out of the water and accumulate on the riverbed.

Front

What is an example of erosion caused by ice?

Back

Glaciers can cause erosion by scraping and carving out valleys as they move, transporting large amounts of rock and sediment.
