Weathering, Erosion, and Deposition

Front

What is chemical weathering?

Back

Chemical weathering is the process by which rocks are broken down through chemical reactions, leading to changes in their mineral composition.

Front

What is an example of chemical weathering?

Back

Oxidation is an example of chemical weathering.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks through physical forces without changing their chemical composition.

Front

How does climate affect weathering?

Back

Climate affects the rate of both physical and chemical weathering; for example, higher temperatures and moisture can increase the rate of chemical reactions.

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 by which sediments, soil, and rocks are added to a landform or land mass.

Front

What role does gravity play in erosion?

Back

Gravity can cause rocks and soil on steep slopes to move downhill, contributing to erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks in place, while erosion involves the movement of those broken materials to a different location.

Front

What is an example of physical weathering?

Back

Frost wedging, where water freezes in cracks of rocks and expands, is an example of physical weathering.

Front

What is the significance of pressure changes in weathering?

Back

Pressure changes can lead to physical weathering, but they are not considered a form of chemical weathering.
