The properties of a mineral

Igneous rocks: Are formed when
magma cools down. It is divided in
two parts: intrusive (plutonic):The
magma cools slowly inside the
earth,and the second part is
extrusive (volcanic) rocks are when
the magma cools down quickly on the
Metamorphic rocks: Are formed
when rocks are put at high
changes but the rock doesn't melt.
