Front

What is erosion?

Back

Erosion is the process by which natural forces like water, wind, or ice move sediments from one location to another.

Front

What is weathering?

Back

Weathering is the breaking down of rocks into smaller pieces due to environmental factors like water, temperature changes, and ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down or deposited in a new location after being transported by erosion.

Front

What landform is created by the slow movement of glaciers?

Back

A U-shaped valley is formed by the slow movement of glaciers carving through the landscape.

Front

What is a delta?

Back

A delta is a landform created at the mouth of a river where sediments are deposited, forming a triangular shape.

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 is a canyon?

Back

A canyon is a deep valley with steep sides, often formed by the erosion of a river over a long period.

Front

What role does water play in weathering?

Back

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

Front

What is a landslide?

Back

A landslide is the sudden movement of rock and soil down a slope, often caused by gravity and erosion.

Front

What is a river delta?

Back

A river delta is formed when a river slows down as it meets a larger body of water, causing sediments to settle and create new land.
