1. Calcareous Ooze: This sediment is primarily composed of the calcium carbonate shells of foraminifera (single-celled organisms), coccolithophores (tiny algae), and pteropods (small, free-floating snails). It's often found in warm, shallow waters.
2. Siliceous Ooze: This sediment is made up of the silica skeletons of diatoms (algae) and radiolarians (single-celled organisms). It's typically found in cold, nutrient-rich waters, like those found in the polar regions and deep ocean currents.
