Weathering, Erosion, & 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 is the process where solid material (sediment) moved by wind and water settles on the surface of land or the bottom of a body of water.

Front

What is sediment?

Back

Sediment is solid material (matter) that is moved by wind and water and settles on the surface of land or the bottom of a body of water.

Front

What is a delta?

Back

A delta is a fan-shaped area where a river meets the ocean, formed when sediment and rock are deposited at the end of the river.

Front

How does weathering differ from erosion?

Back

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

Front

What role does gravity play in erosion?

Back

Gravity helps to move soil and rock downhill, contributing to erosion.

Front

Can weathering occur without erosion?

Back

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

Front

What are the agents of erosion?

Back

The agents of erosion include wind, water, ice, and gravity.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water freezes in cracks of rocks and expands, causing the rocks to break apart.
