Weathering and Erosion Practice Test

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals 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 after erosion.

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 their breakdown.

Front

What is mass wasting?

Back

Mass wasting is the movement of rock and soil down a slope due to gravity, which can include landslides and mudslides.

Front

How do rivers contribute to erosion?

Back

Rivers erode the land by carrying away soil and rocks as they flow, shaping the landscape over time.

Front

What role does rainwater play in weathering?

Back

Rainwater can enter cracks in rocks, freeze, and expand, causing the rocks to break apart, a process known as freeze-thaw weathering.

Front

What are sand dunes formed by?

Back

Sand dunes are formed by the deposition of sand carried by wind, often found in deserts and along coastlines.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water.
