From inorganic bodies striking example is the old, long lying core. His cover is formed from a layer into the layer of rust. This the layer thickens from year to year may be as long as the process is not reaches the phase in which the outer surface of the nucleus loses from rain and wind the same as the inside of the kernel gets from the future the oxidation of iron. When large mineral masses, stones, boulders, rocks generally find some action of the surrounding conditions, it seen only by the destruction of the surface, for example from freezing of absorbed water: this fact, although rather mechanical than chemical, also illustrates the essential truth. Sometimes there is therefore "a rolling stone". On the surface of the stone formed more loose in its consistency layers, each of which has the greatest thickness in the more open places, quickly disintegrates under the action of weathering and thus gives the mass of the shape is more rounded than before, finally, being on the convex surface, it is easy to put in motion. But of all possible examples, maybe the most wonderful one that can be seen on the West Bank of the Nile in Filah where the outer part of a granite ridge 100 feet high turned over time in collection valuearray masses, varying from the yard and up to 6-8 feet diameter.
