Question
Which statement best describes the formation of metamorphic rocks?
Magma cools and crystallizes slowly beneath Earth’s surface.
Liquid lava erupts from a volcano and cools quickly at Earth’s surface.
Sand and gravel are deposited at the mouth of a river and, over time, form layers that solidify into rock.
Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure.

The statement that best describes the formation of metamorphic rocks is:
"Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure."
Metamorphic rocks are formed from pre-existing rocks (either igneous, sedimentary, or other metamorphic rocks) that undergo changes due to extreme heat, pressure, and/or chemically active fluids without completely melting.
