Question

describe how a metamorphic rock might become a sedimentary rock over time.
a metamorphic rock melts, cools, and undergoes recrystallization.
b metamorphic rock is intruded by igneous rock and it melts, cools, and becomes solid again.
c metamorphic rock undergoes weathering, erosion; the particles are deposited and undergo lithification.
d metamorphic rock is buried deep in the earth. it undergoes recrystallization and is then uplifted to the surface.

Explanation:

Sedimentary rocks form from sediments. Weathering and erosion break down metamorphic rocks into particles. These particles are transported, deposited, and then undergo lithification (compaction and cementation) to form sedimentary rocks. Option A describes the process to form igneous rock from metamorphic rock by melting and recrystallization. Option B describes a process related to igneous - rock intrusion and melting - cooling cycle. Option D describes a process of metamorphism and uplift, not sedimentary rock formation from metamorphic rock.

Answer:

C. Metamorphic rock undergoes weathering, erosion; the particles are deposited and undergo lithification.
