The word granite comes from the Latin word granum, a grain, because granite is made of lots of smaller bits of quartz and feldspar stuck together (think of our word granary, a place where you store grain). Granite comes in different colors, usually pink to gray or sometimes black. Granite's a very hard stone. It's hard because it formed as hot liquid stone, and so the molecules inside it are all jumbled up any which way, instead of lying in layers as in sedimentary rocks like limestone or slate.
