Question

Quizplus · Accepted Answer

The Atlantic has a thicker layer of pelagic sediments than the Pacific for a couple of reasons. First, there are more rivers that feed sediment into the ocean. Also, the Atlantic has a smaller area than the Pacific. The Pacific has more topography and trenches for sediments to become trapped in. The topography allows less sediment to reach deep pelagic depths. Information can be found in the section Pelagic Sediments Vary in Composition and Thickness.
