Question

Marine sediments that originate in the warm tropical surface ocean would create deposits in the deep sea composed primarily of ___________.

A. Volcanic ash
B. Calcium carbonate
C. Metal sulfides
D. Quartz sand
E. Silica

Answer 1

Marine sediments that originate in the warm tropical surface ocean create deposits in the deep sea composed primarily of calcium carbonate.

Step-by-step explanation:

The marine sediments that originate in the warm tropical surface ocean and create deposits in the deep sea are primarily composed of calcium carbonate. Calcium carbonate is a major component of marine organism shells, and over time, these shells form sediments on the ocean floor. This process eventually leads to the formation of limestone, which is the largest carbon reservoir on Earth.
