Granite is quarried in large blocks and then sent to
a location where it can be cut and polished. The surface of granite can
be polished just by "sanding" the surface with very fine sand
paper. This would be equivalent to tumbling a rock until it is smooth.
Granite is used in many building and ornamental
places. It is useful for statutes as well as counter tops in
kitchens. Many gravestones are made of granite because it is resistant
to erosion. So the next time you sit at a counter or walk by a building
of granite, you can say that this was formed in large plutons within the
crust of the Earth.
