Detailed explanation-1: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.
Detailed explanation-2: -Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta.
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.
Detailed explanation-4: -The first erosional process that occurs in a river is hydralic action, which is where water is forced into cracks in the river bed and channel which compresses trapped air, making the cracks larger which can cause material to chip away and fall off.
Detailed explanation-5: -Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
