Erosion as land erosion is the disappearing of the land, such as beaches, land for farm, homes etc....erosion of cars etc where the metal deterriates and becomes rusted through......
There are several types of erosion. Such as in cars, the break down of the metal, causing rust. Then there is erosion due to lack of vegetation. Some countries are loosing much of their farm land and it is turning into desert eroding due to high winds. There is also the example of erosion, as in teeth eroding, cavities, causing loss teeth, etc. So erosion is basically something altered for the worse by outside elements
Ruts, potholes, loss of soil, eroded areas, built up mud that clogs drains and channels.
