WebGranite is an igneous rock and as such is formed when molten rock, magma, cools slowly. Magma is found between the mantle and the crust of the earth, and often flows towards the surface of the earth. As the magma rises to the surface though it starts to cool down, and unless it finds an escape route, could solidify as an intrusive rock formation. WebMagma and Igneous Rocks.
