Front

What causes extreme heat when metamorphic rocks are formed?

Back

The fiery hot magma in the Earth's mantle.

Front

What is an intrusive rock?

Back

Igneous rock that forms when magma hardens beneath Earth's surface.

Front

What type of rock is formed from extreme temperature and pressure deep within the Earth?

Front

What must happen for sedimentary rock to change into igneous rock?

Front

What is the process of sedimentary rock formation?
