Igneous rocks form from cooling lava or magma.
Igneous rocks that cool from lava have a much shorter cooling time than rocks that cool from magma, this is because magma is underneath the earths surface and lava is above the surface.
Lava is exposed to much cooler temperatures than it had in the middle of the volcano so it cools much quicker. Since igneous rocks made from lava cool much quicker they have a smaller crystal size.
An igneous rock that formed from magma has time for the crystals to grow because the temperature difference is much less significant than if it had been formed from lava. Metamorphic rocks form from heat and pressure being exerted onto a rock weather it is an igneous rock, a sedimentary rock or a metamorphic rock.
