Erosion Review 1

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural forces such as water, ice, and temperature changes.

Front

What is the main cause of canyon formation?

Back

Moving water is the major cause that forms canyons, such as the Grand Canyon.

Front

How do weathering and erosion work together?

Back

Weathering breaks down rocks, and erosion transports the broken pieces, changing the Earth's surface.

Front

What is the main agent that causes landslides?

Back

Gravity is the main agent that causes landslides, mudflows, slumps, and creeps.

Front

What is wind erosion?

Back

Wind erosion is the process by which wind removes and transports soil and sand from one location to another.

Front

How does vegetation affect erosion?

Back

Vegetation decreases erosion by holding soil in place with roots and reducing the impact of raindrops.

Front

What is the role of water in erosion?

Back

Water can erode land by flowing over it, carrying away soil and rock, and creating features like rivers and valleys.

Front

What is ice wedging?

Back

Ice wedging is a type of weathering where water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.

Front

What are mudflows?

Back

Mudflows are a type of mass wasting that occurs when water-saturated soil and debris flow down a slope.
