Extrusive volcanic rocks are formed on the surface of the earth and cool relatively quickly from lava erupted from a volcano. The rapid cooling of lava on the surface does not allow for visible crystals to form. The crystals are minute and most can only be seen under a microscope. Basalt is an example of an extrusive igneous rock.
Intrusive igneous rocks are formed when magma cools within the crust. This magma cools slowly and so crystals develop in these rocks. Granite is an intrusive igneous rock.
