Weathering Erosion Deposition Review

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

What is erosion?

Back

Erosion is the movement of soil and rock from one location to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where materials like soil and rocks are dropped in new places after being transported by erosion.

Front

How does weathering differ from erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to new locations.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, expands, and breaks the rock apart.

Front

What is an example of erosion caused by wind?

Back

An example of erosion caused by wind is sand dunes being formed as wind blows sand from one area to another.

Front

What is sedimentation?

Back

Sedimentation is the process of settling and accumulating of particles, often occurring in bodies of water.

Front

What is the impact of deposition on landforms?

Back

Deposition can create new landforms such as deltas, beaches, and riverbanks by accumulating sediment.

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

How can human activity affect erosion?

Back

Human activities like deforestation and construction can increase erosion by removing vegetation that stabilizes soil.
