Weathering, Erosion, Deposition Flashcard

Front

What is Weathering?

Back

Weathering is the process that breaks down rocks 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 at the end of rivers or in lakes.

Front

How does Weathering differ from Erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to a new location.

Front

What role does water play in Weathering?

Back

Water can cause chemical weathering by dissolving minerals and can also contribute to physical weathering through freeze-thaw cycles.

Front

What is an example of Erosion?

Back

An example of erosion is when a river carries away soil and rocks from its banks, creating a wider riverbed.

Front

What is an example of Deposition?

Back

An example of deposition is the formation of a delta at the mouth of a river where sediment is deposited as the river slows down.

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 Biological Weathering?

Back

Biological weathering occurs when living organisms, such as plants and animals, break down rocks through their activities.
