Tap again to see term . Meteor debris consists of mainly silica and nickel. There are four types of marine sediments mainly are lithogenous, biogenous, hydrogenous, and cosmogenous sediments. The thickest (>40 m) sediment buildup contoured on the map occurs on the upper slope southwest of the Marquesas Keys in 80 to 190 m of water. However, sedimentation rates near the mouths of large rivers with high discharge can be orders of magnitude higher. Why does the current flow so fast around Cape Horn. Where are the thickest marine sediments located? a. "Ooze" any sediment that is more than 30% biogenous, that is to say, from plant or animal matter. Marine sediments deposited near continents cover approximately 25 percent of the seafloor, but they probably account for roughly 90 percent by volume of all sediment deposits. Which type of sediment covers the greatest seabed area? Usually, because of the erosion of the continents these sediments occur and get deposited at the surface of the ocean floor.
