Detailed explanation-1: -Answer. Answer: (D) The movement of soil by wind or water.
Detailed explanation-2: -Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
Detailed explanation-3: -Scalding. Scalding can occur when wind and water erosion removes the top soil and exposes saline or sodic soils. Raindrop impact alone can result in large amounts of soil being moved. However water or wind moving over the surface will remove more soil, and contribute to sheet, rill and gully erosion.
Detailed explanation-4: -What Is Erosion? Erosion is a geological process in which earthen materials (i.e., soil, rocks, sediments) are worn away and transported over time by natural forces such as water or wind; sometimes this is sped up by poor management or other human impacts on land.
Detailed explanation-5: -Soil erosion is caused by both natural and anthropogenic factors that affect all landforms. Plant and residue cover protects the soil from raindrop impact and splash, tends to slow down the movement of runoff water, and allows excess surface water to infiltrate.
