Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where sediments are dropped off in a new location 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 deposits sediments into a larger body of water.

Front

How do sand dunes form?

Back

Sand dunes form when wind blows sand into piles, creating mounds of sand.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away sediments and shaping the landscape.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces from one place to another.

Front

What is an example of mechanical weathering?

Back

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

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is when acid rain reacts with minerals in rocks, changing their composition.

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.
