1. how would a sample of sedimentary rock become a metamorphic rock?\nweathering and erosion\nheat and pressure\ncementation and compaction\nmelting and cooling

Answer

Brief Explanations:

Sedimentary rocks transform into metamorphic rocks when subjected to high - heat and high - pressure conditions deep within the Earth's crust. Weathering and erosion break down rocks but don't change sedimentary to metamorphic. Cementation and compaction form sedimentary rocks. Melting and cooling form igneous rocks.

Answer:

B. heat and pressure
