Intrusive vs extrusive rocks the key difference between intrusive and extrusive rocks is that the intrusive rocks are formed from magma whereas the extrusive rocks are formed from lava. Intrusive rocks are very hard in nature and are often coarse grained. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals.
