What is the sediment called that is derived primarily from the products of weathering on the continents?
terrigenous sediment
What part of speech is sediment?
Sediment is a noun.
What is the plural of sediment?
Sediments is the plural of sediment
What are rocks snd soil deposited by streams called?
they are deposited by sediment
What is deposition of sediment outside the banks of a river?
Sediment
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.

A simple method of obtaining an actual sample of seafloor sediment is with a?
grab sampler
Flat seafloor in the deep ocean formed when deposits of sediment filled valleys?
continental slope
How might a lowering of the pH of seawater affect the abundance of calcareous sediment on the seafloor?
Lowering the pH to less alkaline and more acidic levels would cause more calcareous materials to dissolve in seawater thereby reducing the abundance of calcareous sediment on the seafloor.
Where is the greatest sediment thickness on the ocean floor?
Near the trenches, or in the seafloor furthest away from spreading centers.
What is commonly used to determine the age of seafloor samples recovered by the deep-sea drilling project?
sediment cores
Where on the ocean floor is sediment the thickest?
the thickest accumulation of sediment on the ocean floor is at the CONTINENTAL SLOPES AND RISES. :)
Sediment that originates from the continents is called?
Marine sediments are typically terrigenous in nature, which means they came from the land. Sediments that originate from the continents are called terrigenous.
What happens to old seafloor rock down in the trenches?
The trenches catch most of the sediment from the plates that break up and sink deeper into the water. This causes the upper plates to grow.
