Weathering, Erosion and Deposition Review

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

Front

What is deposition?

Back

Deposition is the process where materials transported by erosion are dropped off in a new location, forming new landforms like deltas.

How is a U-shaped valley formed?

Back

A U-shaped valley is formed by a glacier moving slowly and carving the valley over time.

Front

What causes the Grand Canyon to change shape?

Back

The changes in the shape of the Grand Canyon are primarily due to water erosion.

Front

True or False: Glaciers can reshape the landscape over thousands of years.

Back

True

Front

What are deltas?

Back

Deltas are landforms that form at the mouths of rivers where sediment is deposited as the river meets a body of water.

Front

What is the difference between weathering and erosion?

Back

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

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by carrying away loose particles, especially in dry and sandy areas.

Front

What is a canyon?

Back

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