Question

What rock type can form from the accumulation of the silica shells of marine microorganisms on the seafloor?

1) Igneous rock
2) Sedimentary rock
3) Metamorphic rock
4) None of the above

Answer 1

Sedimentary rock can form from the accumulation of silica shells of marine microorganisms on the seafloor.

Step-by-step explanation:

The rock type that can form from the accumulation of the silica shells of marine microorganisms on the seafloor is sedimentary rock.Sedimentary rocks form when broken pieces of other rocks from weathering processes get cemented together or when minerals precipitate out of a solution and are cemented together. In this case, the silica shells of marine microorganisms can accumulate and form a sedimentary rock. Examples of sedimentary rocks that can form from the accumulation of silica shells include chert and diatomite.Therefore, the correct answer is Sedimentary rock.
