Changing Earth's Surface

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to natural forces like wind, water, and ice.

Front

What is erosion?

Back

Erosion is the movement of weathered materials from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

What is a delta?

Back

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

Front

What causes canyons to form?

Back

Canyons are formed by the erosion of rock by fast-moving water over a long period of time.

Front

What role does ice play in changing the Earth's surface?

Back

Ice can cause weathering and erosion by freezing and thawing, which cracks rocks and moves materials.

Front

What is coastal erosion?

Back

Coastal erosion is the process where coastlines are worn away by the action of waves, currents, and tides.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to new locations.

Front

How does wind contribute to weathering?

Back

Wind carries sand and other particles that can wear away rocks, causing weathering.

Front

What is loess?

Back

Loess is a type of soil made up of fine particles that have been deposited by wind.
