What causes soil erosion?
A
strong wind
B
cooking food
C
growing crops
D
none of above
Explanation: 

Detailed explanation-1: -Soil particles erode when shear stress exerted by the wind against the ground surface exceeds the forces tending to hold the particles in place. The eroding particles may be transported in saltation, creep, or suspension.

Detailed explanation-2: -Significant wind erosion occurs when strong winds blow over light-textured soils that have been heavily grazed during periods of drought. Wind erosion is also a natural process.

Detailed explanation-3: -What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Detailed explanation-4: -Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide.

Detailed explanation-5: -The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.
