All types of rocks can undergo melting to produce magma that will eventually crystallize to form new igneous rocks.
- Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma.
- The minerals that make up igneous rocks crystallize at a range of different temperatures.
- These Igneous rocks are usually formed deep inside the earth's crust
- Granite and pumice are examples of igneous rocks
