Its sedimentation is composed primarily of plankton remains. It is the largest single region on Earth for life, and its floor often feature namesake (*) plains created by turbidity currents. Below the bathyal zone and above the haldal zone, its upper boundary is the 4-degree-Celsius isotherm and its typical pressure is 200 to 600 atmospheres. For 10 points— identify this part of the ocean extending from about 2 to 6  kilometers below the surface.
