A sedimentary rock unit was exposed to heat and pressure deep within Earth. The rock changed to metamorphic rock. Over a long time, it was exposed at Earth’s surface. How did this metamorphic rock unit reach Earth’s surface? 

• Deposition acted on the rock unit, causing it to be exposed at the surface over time.
• Magma brought it up to Earth’s surface, where it flowed from a volcanic vent as lava.
• Weathering and erosion of the rock above it caused the metamorphic rock to uplift and become exposed.
• Weathering of the metamorphic rock brought pieces up to Earth’s surface.
