The Sediment Layer On The Ocean Floor Quizlet

Latin for hole bearers.

The sediment layer on the ocean floor quizlet. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. Neritic sediment is mostly. The ocean basin floor is everywhere covered by sediments of different types and origins. Because large particles settle faster turbidity currents leave layers of sediment called turbidite layers.

Foraminifera f ə ˌ r æ m ə ˈ n ɪ f ə r ə. Sediments in the deep sea fine grained collect slowly on sea floor. Abyssal clay on deep sea floor. Informally called forams are single celled organisms members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses.

The post extinction layer of sediments contains. Pelagic sediment is composed of clay particles and microskeletons of marine organisms that settle slowly to the ocean floor. They can carry coarse grain sized sediments to and across the deep ocean floor adjacent to the continental shelves. Mircofossils biogenous sediments from the period after the dinosaurs.

Some of these organic sediments are called calcareous or siliceous oozes because they are so thick and gooey. The sediment cover in the pacific basin ranges from 300 to 600 metres. As the sea floor spreads thermal subsidence of the plate which has the effect of increasing depth may bring the carbonate layer below the ccd. The carbonate layer may be prevented from chemically interacting with the sea water by overlying sediments such as a layer of siliceous ooze or abyssal clay deposited on top of the carbonate layer.
