What is erosion?

Back

Erosion is the process of wearing away rocks and soil by natural forces such as water, wind, and ice.

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes.

Front

What are constructive forces?

Back

Constructive forces are natural processes that create landforms, such as volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion and weathering.

Front

How does fast moving water shape landforms?

Back

Fast moving water can carve out canyons and valleys by eroding the soil and rock.

Front

What is terrace farming?

Back

Terrace farming is a method of growing crops on the sides of hills or mountains to reduce soil erosion.

Front

What role does wind play in weathering?

Back

Wind can erode rocks and soil by carrying small particles that wear away surfaces.

Front

What is sediment?

Back

Sediment is small particles of rock and soil that are transported by water, wind, or ice.

Front

How does ice contribute to weathering?

Back

Ice can cause weathering by expanding in cracks of rocks when it freezes, leading to the rocks breaking apart.
