The rock cycle — Science Learning Hub

There are three main types of rock igneous, sedimentary and metamorphic. Igneous rocks. Magma is a hot mix of melted minerals, and igneous rocks are formed when it cools. Cooling can happen quickly above ground to form volcanic rocks such as basaltrhyolite and andesite. Cooling can also happen slowly below the surface to form what are called plutonic rocks, such as granite. Sedimentary rocks
