C & D Forces Flashcard II: Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to natural forces like 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 occurring at the mouth of rivers or ocean floors.

Front

How do ocean waves contribute to cliff formation?

Back

Ocean waves can erode the base of cliffs, washing away rock and sediment, which can lead to the formation of steep cliffs.

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 new locations.

Front

What is a landslide?

Back

A landslide is a rapid movement of rock and soil down a slope, which is not considered a slow change to the Earth's surface.

Front

Can you give an example of weathering?

Back

An example of weathering is flood water pounding against a canyon wall, causing it to wear down over time.

Front

What happens during deposition?

Back

During deposition, bits of broken rock and soil are dropped in new places, changing the landscape.

Front

What role do plant roots play in weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart, which is a form of weathering.

Front

What is the impact of erosion on soil?

Back

Erosion can lead to the loss of fertile topsoil, which is essential for growing crops and maintaining healthy ecosystems.
