Basalt and Granite

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 Both will hurt if you drop ....
