Rock Transformation Review

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 the Earth's interior, it can melt into liquid rock and form igneous rock.

• No, Igneous rock can only form other igneous rocks.

• No, Sedimentary rocks can only form other sedimentary rocks.

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 sediments and then compacted.

• It was heated and put under pressure.

Could material from this sedimentary rock ever form igneous rock?

• No, igneous rock can only form from igneous rock.

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

• Yes, if sedimentary rock is exposed to energy from the sun at the surface, it can melt and cool and form igneous rock.

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