Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do (2007) were used. On the seafloor, sediments are thinnest near spreading centers (young seafloor) and thicker away from the ridge, where the seafloor is older and has more time to accumulate. American Film Market 2021, This is because continents provide lots of sediment in the form of runoff of small pieces of rock and other debris from land. It can be said that the bottom is younger and no sediments older than 150,000,000 years can be found here, but on the other hand, the sediments get thicker and older with time as well.

What Do You Mean by Marine Sediment? 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. Near mid-ocean ridge systems where new oceanic crust is being formed, sediments are thinner, as they have had less time to accumulate on the younger crust. Write.
