Rocks formed from the solidification of molten magma
which is of two types i.e. intrusive and Extrusive rock ; these rocks are called asSolution
Volcanic rocks are igneous rocks that are formed above the ground from the lava. Plutonic rocks are igneous rocks that are formed deep under the Earth's surface from the magma.
