Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process where rocks on Earth's surface break apart or change without moving anywhere.

Front

What is erosion?

Back

Erosion is the movement of soil and rock by wind, water, ice, and gravity.

Front

What is deposition?

Back

Deposition occurs when eroded materials stop moving and begin to build up.

Front

How does deposition change the Earth's surface?

Back

Over long periods of time, deposition may change the Earth’s surface by forming new land features.

Front

What is an example of erosion?

Back

A farmer's topsoil being blown away during a hurricane is an example of erosion.

Front

What are the main agents of erosion?

Back

The main agents of erosion are wind, water, ice, and gravity.

Front

What is the difference between weathering and erosion?

Back

Weathering involves breaking down rocks without movement, while erosion involves the movement of soil and rock.

Front

Can weathering occur without erosion?

Back

Yes, weathering can occur without erosion, as it involves breaking down rocks without moving them.

Front

What role does gravity play in erosion?

Back

Gravity helps to pull soil and rock down slopes, contributing to erosion.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks into smaller pieces without changing their chemical composition.
