Granite is an igneous rock and is formed by magma coming from
under the earth's surface, as already said above. It is the
substance that these rocks are made of. They are all, including
the smallest ones, made of this hard substance. Nowadays granite
is the most used material for construction. These rocks are used
as historical and geographical display and have been given great
importance according to the researches done since the last few
