can anyone give short define of weathering and soil erosion
Answers
Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. Therefore, this is the layer that farmers want to protect for growing their crops and ranchers want to protect for growing grasses for their cattle to graze on.
The scenes of the world are continuously mutating. Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering. The action of the elements of climate and weather, animals, and plants on the land surfaces to break them down biologically, chemically, and physically is called weathering. It is the breakdown and decay of rocks in situ. It can be a very elongated slow procedure, taking hundreds of years. However, weathering can also be rapid, such as the damage to pavements or roads after a cold, frosty winter.
