Igneous Rocks
They can be divided into plutonic and volcanic rocks. Plutonic rocks are solidified slowly underground; crystals are visible with the naked eye. Volcanic rocks are solidified quickly above ground. Crystals are too small to be visible with the naked eye.
These are rocks comprise of detrital rocks (rocks consisting of fragments of pre-existing rocks) and those formed by chemical precipitation. They are normally classified by grain size.
