4th grade Weathering, Erosion, Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as 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, forming new landforms.

Front

What natural agent forms U-shaped valleys?

Back

U-shaped valleys are formed by the erosion of glaciers.

Front

What is a delta?

Back

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

Front

How do sand dunes form?

Back

Sand dunes form from the deposition of sand by wind, creating mounds or hills of sand.

Front

What role does ice play in weathering?

Back

Ice can cause weathering by freezing and thawing, which breaks rocks apart.

Front

What is the difference between weathering and erosion?

Back

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

Front

What is an example of erosion caused by water?

Back

Rivers can erode land by cutting into it and carrying away sediments.

Front

What is a canyon?

Back

A canyon is a deep valley formed by the erosion of rock, often by a river.
