Question

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

Explanation:

Terracing in soil conservation involves creating flat - like steps on steep slopes. This helps to slow down the flow of water, reducing the force that would otherwise cause soil to be washed away. The first option is incorrect as terracing is not about removing topsoil. The second option is wrong because terracing aims to reduce, not increase, soil erosion. So the main purpose of terracing is to prevent soil erosion on steep slopes by creating flat areas.

Answer:

to prevent soil erosion on steep slopes by creating flat areas
