उत्तर १
The blowing away or washing away of land surface by wind or water is known as soil erosion.
उत्तर २
The removal of topsoil which is rich in humus and nutrients by flowing water or wind is known as soil erosion. If this process continues further then all soil may get washed away and the rocks underneath may get exposed. It may lead to the loss of all valuable resources because nothing grows as such on the rocks.
