Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often caused by water, wind, 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 at the end of a river.

Front

What natural feature was formed by the Colorado River through erosion?

Back

The Grand Canyon.

Front

What is a delta?

Back

A delta is a fan-shaped area where a river meets the ocean, formed by the deposition of sediment.

Front

How does water cause weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart.

Front

What role does wind play in weathering?

Back

Wind can carry sand and other particles that blast against rocks, wearing them down over time.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when ice freezes in rock cracks and expands, causing the rock to break.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to water and acids.
