Hi Leighdaniellesu .A soil erosion is the washing or blowing away (by wind or water) of the top layer of soil (dirt).It can be caused byRemoval of topsoil faster than the soil forming processes can replace it, due to natural, animal, and human activity (over grazing, over cultivation, forest clearing, mechanized farming, etc.). Soil erosion results in land infertility and leads to desertification and devastating flooding. It is also the mechanical process of wearing or grinding something down (as by particles washing over it)
