Earth Science- Weathering and Erosion

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What are the main agents of erosion?

Back

Wind, water, glaciers, and gravity.

Front

How does wind contribute to erosion?

Back

Wind can blow soil over large distances and smooth the surfaces of soft rocks.

Front

What type of erosion is responsible for landslides?

Back

Gravity causes landslides by pulling soil and rock down slopes.

Front

What factors influence the rate of weathering?

Back

Climate, rock composition, and human activity are key factors; oxygen levels in the air do not significantly affect weathering.

Front

How do plants contribute to weathering?

Back

The roots of plants can break apart rocks, aiding in the weathering process.

Front

What is a drumlin?

Back

A drumlin is a streamlined hill formed by glacial activity, typically composed of unsorted sediments.

Front

What does the direction of ice movement indicate about drumlins?

Back

The direction of ice movement can be inferred from the orientation of drumlins, which are formed in the direction the ice advanced.

Front

What is the difference between sorted and unsorted sediments?

Back

Sorted sediments are particles of similar size, while unsorted sediments contain a mix of different sizes.
