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: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-3: -Mechanical weathering-occurs when physical forces break rock into smaller and smaller pieces without changing the rock’s mineral composition.

Detailed explanation-4: -Mass movement is an erosional process that moves rocks and sediments downslope due to the force of gravity. The material is transported from higher elevations to lower elevations where other transporting agents like streams or glaciers can pick it up and move to even lower elevations.

Detailed explanation-5: -Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity.
