Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the physical and chemical breakdown of rocks at Earth's surface.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as wind or water.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or settled after being transported by wind, water, or ice.

Front

How do plants contribute to weathering?

Back

Plants can weather rocks through both chemical processes (by releasing acids) and physical processes (by growing roots that break rocks apart).

Front

What role does water play in weathering?

Back

Water can weather rocks by freezing in cracks, expanding, and breaking the rock apart.

Front

What is the Grand Canyon primarily shaped by?

Back

The Grand Canyon is primarily shaped by erosion from the Colorado River.

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.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the breaking of rocks due to freeze-thaw cycles.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is the dissolution of limestone by acidic rainwater.

Front

How does wind contribute to erosion?

Back

Wind can carry away loose soil and sand, reshaping landscapes over time.
