Erosion is the process by which soil, rock, or other surface material is worn away and transported from one location to another by natural forces such as wind or water.

Front

Does erosion ever stop?

Front

What is formed when soft rock is inside hard rock?

Back

An arch is formed when soft rock is eroded away, leaving the harder rock standing.

Front

How can rough rocks become smooth?

Back

Rough rocks can become smooth through the process of erosion, where they are worn down by wind, water, and other natural forces.

Front

What is a concrete barrier used for in relation to erosion?

Back

A concrete barrier is used to protect structures, such as houses built on hills, from the effects of erosion and landslides.

Front

What happens to rocks after millions of years due to erosion?

Back

After millions of years, rocks can be worn down to the point where they turn into sand.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals at the Earth's surface, while erosion involves the movement of those materials from one location to another.

Front

What role does vegetation play in erosion?

Back

Vegetation helps to prevent erosion by stabilizing the soil with roots and reducing the impact of raindrops on the soil surface.

Front

What is sediment?

Back

Sediment is the material that is broken down by weathering and erosion and is transported by wind, water, or ice.
