Weather and Erosion

Front

What is erosion?

Back

Erosion is the process by which natural forces like water, wind, and ice wear away rocks and soil.

Front

What are the main causes of erosion?

Back

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

Front

How does water cause erosion?

Back

Water can flow over land, carrying away soil and rocks, especially during heavy rain or floods.

Front

What is a mudslide?

Back

A mudslide is a fast erosion event caused by moving water and gravity, where soil and debris flow down a slope.

Front

What role does ice play in erosion?

Back

Ice can cause erosion by freezing and expanding in cracks of rocks, leading to breaking and wearing away of the rock.

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.

Front

What natural feature was formed largely by water erosion?

Back

The Grand Canyon was largely formed by the erosion caused by the Colorado River.

Front

What is the effect of sunlight on roads?

Back

Sunlight can cause roads to crack due to the expansion and contraction of materials.

Front

What is a flood?

Back

A flood is an overflow of water that submerges land that is usually dry, which can cause erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.
