    Granite is an intrusive rock that is formed when magma cools inside the crust. This slow cooling gives time for crystals to grow making it more coarsely grained than an extrusive rock. This coarse grain makes granite a favorite of rock climbers. Basalt on the other hand has a smooth texture from rapid cooling usually by water.
