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 movement of weathered rock and soil from one location to another, often caused by water, wind, 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 creating new landforms.

Front

How do glaciers shape the landscape?

Back

Glaciers shape the landscape by eroding the land beneath them and depositing materials as they move, creating features like U-shaped valleys.

Front

What role do plants play in weathering?

Back

Plants weather rocks by growing roots into cracks, which can expand and break the rocks apart.

Front

What is a sand dune?

Back

A sand dune is a hill of sand formed by the wind, often found in deserts or near beaches.

Front

What is the difference between fast and slow changes in the Earth's surface?

Back

Fast changes occur quickly, like landslides and volcanic eruptions, while slow changes happen over long periods, like erosion.

Front

What is an example of a landform created by deposition?

Back

An example of a landform created by deposition is a delta, which forms at the mouth of a river where it meets a body of water.

Front

What natural force is primarily responsible for erosion in rivers?

Back

Water is the primary force responsible for erosion in rivers, as it carries away sediment and shapes the riverbanks.

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley with a characteristic U shape, formed by the erosion of a glacier.
