Question

Answer 2

Mountains are the areas where soil erosion easily occurs when there is as downpour. The major benefit, of course, is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.
