• plastic

How does water causes erosion?

• It doesn't contribute to erosion

The speed of flowing water affects the rate of erosion, too. The faster the water flows, the faster and the farther the erosion would be.

• True

• Flase

How does wind causes soil erosion?

• As the wind blows, it carries light particles of rocks and soil, transporting and depositing them into another place.

• As the wind blows, the particles of rock will be crushed.

• All of the above.

This agent has the major contribution to the rate of soil erosion.
