Description
Granite rocks are
igneous rocks, which were formed by slowly
cooling pockets of magma that were trapped
beneath the earth's surface. Granite is used
for long lasting monuments and for trim and
decoration on buildings. Igneous rocks are
called fire rocks and are formed either
underground or aboveground. Underground,
they are formed when the melted rock, called
magma, deep within the earth becomes trapped
in small pockets. As these pockets of magma
cool slowly underground, the magma becomes
igneous rocks. Igneous rocks are also formed
when volcanoes erupt, causing the magma to
rise above the earth's surface. When magma
appears above the earth, it is called lava.
Igneous rocks are formed as the lava cools
above ground.
