Stone

Stone
==Stones are a part of the earth, it's produced by the mixture of Vulcan lava and sea water, then as the time passes and erosion and other natural effects moved this pieces apart, the stone began to take part in the environment. I just know a kind of stone: granite, but I don't know exactly how it gets its form. Stones are hard, and in big measures they tend to be heavy, although I know there's a kind of stone that is not actually heavy, they're colors are the same as the earth's such as brown and gray. Stone is one of the older construction materials because it hard but it can be modified, like stone carving so it can be used to build houses, shelters, refuges, walls, borders, and also now days as decoration, floor types, etc.==
