Question

Which processes must happen for sand to eventually become metamorphic rock? Name and
briefly describe the process in one to two sentences.

Answer 1

For sand to become metamorphic rock, it must first undergo lithification, where sediment is compacted and cemented to form sedimentary rock, followed by metamorphism. During metamorphism, the sedimentary rock is subjected to increased heat and pressure, causing physical and chemical changes that result in the formation of metamorphic rock.
