I WONDER - What Are Metamorphic Rocks?

Metamorphic rocks start as sedimentary or igneous rocks. They form when mountain ranges push up, causing rocks to be buried and compressed, or when rocks are heated by magma. Examples include marble, slate, and quartzite.

What role does magma play in the formation of metamorphic rocks?

• It cools and forms sedimentary rocks

• It heats rocks causing metamorphism

• It erodes existing rocks

• It creates new minerals

Can you name three examples of metamorphic rocks?

• Marble

• Slate

• Quartzite

• Basalt
