Question

what is the main purpose of terracing in soil conservation? to prevent soil erosion on steep slopes by creating flat areas to increase soil erosion by exposing the soil to heavy rainfall to remove all the topsoil in preparation for new crop planting

Explanation:

Terracing in soil conservation is a practice where flat areas (terraces) are created on steep slopes. This slows down water runoff, reducing the force that causes soil erosion. The second option is incorrect as terracing aims to reduce, not increase, erosion. The third option is wrong because terracing preserves topsoil, not remove it. So the correct reason is to prevent soil erosion on steep slopes by creating flat areas.

Answer:

A. to prevent soil erosion on steep slopes by creating flat areas
