Weathering Erosion Deposition

Front

What is weathering?

Back

The process by which rock materials are broken down by the action of physical or chemical processes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another.

Front

What is deposition?

Back

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

Front

What is physical weathering?

Back

The mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical changes, such as acid rain or oxidation.

Front

What is an example of physical weathering?

Back

Frost wedging, where water freezes in cracks of rocks and expands, breaking the rock apart.

Front

What is an example of chemical weathering?

Back

Acid rain reacting with limestone to form calcium carbonate.

Front

How does gravity affect erosion?

Back

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

Front

What role do plants play in weathering?

Back

Plants can produce weak acids that contribute to chemical weathering and can also break rocks apart with their roots.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials.
