Granite is formed within the crust of the Earth when Felsic magma, that is magma that is rich in Silica, cools down without reaching the surface. Because it remains beneath the surface as it is cooling it forms large crystals (ie, you can see the individual crystals without need of a microscope or hand-lens).

Granite is an igneous rock that forms when a pocket of magma rises into the upper levels of the Earth's crust and slowly cools. Cooling slowly gives granite, which is composed mainly of feldspar and quartz, enough time to develop large crystals that make the stone very hard and strong.

Basalt and granite actually have quite a bit in common. Both are igneous rocks, which means that they cooled from a magma (the earth gets very hot just below the surface, and there is lots of liquid rock available). Both are made up of minerals from the silicate group, so both have large amounts of silicon and oxygen.
