Detailed explanation-1: -Weathering can occur due to chemical and mechanical processes. Erosion is the movement of particles away from their source. Example of erosion: Wind carries small pieces of rock away from the side of a mountain.
Detailed explanation-2: -Wind erosion is also a natural process. The large parallel sand dunes in south-west Queensland, including the Simpson Desert National Park, are the result of wind erosion and deposition over thousands of years. These dunes are constantly moving and roads and tracks can be covered by drifting sands in only a few hours.
Detailed explanation-3: -Rocks carried by glaciers scrape against the ground below, eroding both the ground and the rocks. In this way, glaciers grind up rocks and scrape away the soil. Moving glaciers gouge out basins and form steep-sided mountain valleys. Eroded sediment called moraine is often visible on and around glaciers.
Detailed explanation-4: -Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering.
