Question

what is the process that wears away the surface of the earth?
○ erosion
○ loam
○ topography
○ windbreaks
question 2
true or false? wet soil is easily picked up by the wind and carried away.
○ true
○ false
question 3
what can contribute to erosion? select all that apply.
□ cutting down trees
□ overfarming the same area
□ planting windbreaks
□ crop rotation

Explanation:

Question 1

Erosion is the process of wearing away Earth's surface (e.g., by wind, water). Loam is a soil type, topography is land's shape, windbreaks prevent erosion. So erosion is correct.

Wet soil has more moisture, making it heavier and less likely to be picked up by wind. Dry soil is more easily eroded by wind. So the statement is false.

• Cutting down trees: Removes roots that hold soil, increasing erosion.
• Overfarming the same area: Depletes soil nutrients and structure, making it prone to erosion.
• Planting windbreaks: Reduces wind erosion (prevents, not contributes).
• Crop rotation: Improves soil health, reduces erosion (prevents, not contributes). So cutting down trees and overfarming contribute.

Answer:

A. erosion
