How does a metamorphic rock form?

• Rocks don't form; they stay as they are.

• It melted and cooled.

• It broke into sediment and then compacted.

• It was heated and put under pressure.

Mary and her family go on a trip and they drive over a mountain range. Mary wonders how the rock they see as they drive over the mountain range might be different when they drive back home next week. What would you tell Mary about how the rock will change?

• The rock will probably change a lot. Rock is always changing and transforming.

• The rock is not likely to change very much. Most rock transformation processes happen very slowly.

• The rock will not change at all. Rock just stays as it is.

• The rock might change if it is the right season.

A geology student describes a rock sample she is studying in class. The rock sample is igneous rock, but the student wonders if the material that it formed from was part of a sedimentary rock formation millions of years ago. Could this be correct? Could the material for igneous rock come from sedimentary rock?

• Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

• Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.

• No, igneous rock can only form from other igneous rocks. Sedimentary rock cannot change into igneous rock.

• No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock only forms at Earth’s surface.

On vacation at a lake, Saira’s mom sees an interesting-looking rock formation. Saira just learned about rocks in geology class and tells her mom that the formation is made of gneiss, a type of metamorphic rock. How did this metamorphic rock form?

• Rocks don’t form; they stay as they are.

• It melted and cooled.

• It broke into sediment and then compacted.

• It was heated and put under pressure.

Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock ever form igneous rock?

• No, igneous rock can only form out of other igneous rock. Sedimentary rock cannot change into igneous rock.

• No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock is only at Earth’s surface.

• Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

• Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.
