Soil erosion is caused by?

Soil erosion is caused by?

• A. Not fertilizing and watering
• B. Applying lime at high levels
• C. Large insect and disease infestations
• D. Wearing away of the soil due to water or wind

Answer: (D)

Soil erosion is the wearing away and removal of soil from the surface by natural forces such as water or wind. That direct process is exactly what the description “wearing away of the soil due to water or wind” conveys, so it’s the best answer. The other factors listed—not fertilizing and watering, applying lime at high levels, and infestations of insects or diseases—affect plant health, soil chemistry, or crop vigor, but they do not describe the physical removal and transport of soil by water or wind. Understanding erosion also helps explain why practices like maintaining ground cover, reducing runoff, and using windbreaks are important to protect the soil.
