Weathering, Erosion, and Deposition Test

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural causes such as wind, water, and temperature changes.

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 when sediment is dropped or left somewhere else after being transported by erosion.

Front

How does freezing water cause weathering?

Back

Freezing water expands cracks in rocks, which can lead to breaking the rocks apart.

Front

What can deposition create over time?

Back

Deposition can form new land features such as deltas, beaches, and sand dunes.

Front

What factors affect the rate of erosion?

Back

Factors include the steepness of the hill, intensity of wind, and amount of rainfall.

Front

Which factor does NOT affect erosion?

Back

How much money you paid for the land does NOT affect the rate of erosion.

Front

What is the difference between weathering and 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 vegetation play in erosion?

Back

Vegetation helps to hold soil in place, reducing the rate of erosion.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks without changing their chemical composition.
