Igneous rocks
All types of rocks.
Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
Contact metamorphism
Extrusive igneous rocks such as basalt or rhyolite.
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
Magma is melted rock that is found beneath the surface of the earth.It is called magma
Igneous rocks
Lava. (When it is underground it is called magma)
Igneous rocks are formed when rocks reach the melting point becoming magma, then the magma starts to cool and crystallizes to form igneous rocks. Metamorphic rocks are made when they come in contact with a mass of magma but does not melt providing the energy to drive chemical reactions that recrystallize minerals.
