WebIgneous Rocks. The rate that magma cools determines whether an igneous rock is intrusive or extrusive. The cooling rate is reflected in the rock’s texture. Igneous rocks make up most of the rocks on Earth. Most igneous rocks are buried below the surface and covered with sedimentary rock, or buried beneath the ocean water.
