Answer to Question 1

Biogenous sediments are composed of the remains of live organisms. There are two types of biogenous sediments: calcareous and siliceous oozes. Calcareous deposits are most common in shallow, warm water. Organisms such as corals, mollusks, coccolithophorids, and foraminiferans contribute to the development of calcareous oozes, small calcium carbonate particles on the ocean floor. Siliceous oozes are associated with cooler waters and the remains of organisms with silica in their cell walls or tests such as diatoms and radiolarians.
