Front

What is wind erosion?

Back

Wind erosion occurs when strong winds blow across loose, dry, and bare soil, removing topsoil and causing land degradation.

Front

What can be used to prevent soil erosion?

Back

Grass and plants can be used to prevent soil erosion by holding the soil in place with their roots.

Front

What is the Grand Canyon an example of?

Back

The Grand Canyon is an example of land shaped by water erosion over millions of years.

Front

What is gravity's role in erosion?

Back

Gravity can cause erosion by pulling soil and rocks down slopes, leading to landslides and other forms of erosion.

Front

What is a common effect of wind erosion?

Back

A common effect of wind erosion is the formation of sand dunes in deserts.

Front

How does water erosion change the landscape?

Back

Water erosion can create valleys, canyons, and other landforms by removing soil and rock.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals, while erosion is the movement of those materials from one place to another.

Front

What are some human activities that can increase erosion?

Back

Deforestation, overgrazing, and construction can increase erosion by removing vegetation that protects the soil.
