What are igneous rocks made from?
Igneous rocks are made from the cooling of magma.
How are intrusive igneous rocks made?
Intrusive igneous rocks are made by magma cooling inside a volcano very slowly so it has time to create all of the crystals.
How are extrusive igneous rocks made?
extrusive igneous rocks are made when magma cools very quickly outside of a volcano so that’s the crystals do not have much time to form
