What is weathering?

Back

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

Front

What are the main agents of weathering?

Back

The main agents of weathering are water, wind, ice, and biological activity.

Front

How does wind contribute to weathering?

Back

Wind erodes rocks and soil by carrying small particles that can wear away surfaces over time.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of rivers.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river where it meets a body of water, such as an ocean.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the likelihood of erosion. If plants decrease, erosion is likely to increase.

Front

What role does ice play in weathering?

Back

Ice can cause weathering through a process called freeze-thaw, where water seeps into cracks, freezes, expands, and breaks the rock apart.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one place to another.

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley formed by glacial activity, characterized by a wide, flat bottom and steep sides.
