Chapter 7 Practice Test

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 temperature changes.

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 by which sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of a river.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, shaping the landscape through erosion and deposition.

Front

What is a delta?

Back

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

Front

How do plants and animals contribute to weathering?

Back

Plants and animals can contribute to weathering by breaking down rocks through their roots and burrowing activities.

Front

What evidence suggests a glacier has moved through a valley?

Back

The shape of the valley, often U-shaped, is strong evidence that a glacier has moved through it.

Front

What role does wind play in erosion?

Back

Wind can erode rocks and soil by carrying away small particles, especially in dry and sandy areas.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken materials.

Front

What happens to a river's speed as it approaches its mouth?

Back

A river slows down as it approaches its mouth, which can lead to the deposition of sediment.
