What is erosion?

Back

Erosion is the movement of weathered rock and soil from one place to another, often caused by water, wind, or ice.

Front

What is a mudslide?

Back

A mudslide is a fast erosion event where mud and debris flow down a slope, often caused by heavy rain.

Front

What role does wind play in weathering?

Back

Wind carries sand and other particles that can wear away rocks and surfaces, causing weathering.

Front

What are the main causes of erosion?

Back

The main causes of erosion are water, wind, and ice.

Front

How does ice cause erosion?

Back

Ice can cause erosion by freezing in cracks of rocks, expanding, and breaking the rocks apart.

Front

What is expansion and contraction?

Back

Expansion and contraction refer to the process where materials expand when heated and contract when cooled, which can cause cracks in rocks and roads.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

What is a natural force?

Back

A natural force is a power of nature, such as wind, water, or ice, that can change the landscape.

Front

What is sediment?

Back

Sediment is small pieces of rock and soil that are carried away by erosion.
