Answer:
30% of calcareous material is needed to make an ooze.
Explanation:
The calcareous ooze is one of the distinct and common types of pelagic sediments that are mainly comprised of about 30% of calcareous substances, and that is very fine-grained in nature. These are dominant in calcareous shells, that are mostly the shells of coccoliths and foraminiferous, and are typically intermixed with the mud and clay. These are the most common type of pelagic sediments, that covers nearly 50% of the seafloor, including the abyssal plain.
Therefore, 30% of the total composition is required in order to make an ooze.
