IGNEOUS ROCKS

IGNEOUS ROCKS are formed by the cooling and solidification of molten rocks called MAGMA , ejected from beneath the earth crust .The MAGMA which resulted from a high pressure and teemperature beneath the earth , forces itself towards the earth surface through cracks .As the MAGMA moves towards the surface it comes in contact with lower temperature hence it cools and solidifies to form the IGNEOUS ROCK.
