When sediment sinks into the ocean floor it is called?
When sediment sinks into the ocean floor, it is called sedimentation. Over time, layers of sediment build up and compress to form sedimentary rocks.
How do core samples help scientists learn about earth's history?
Core samples provide a snapshot of past environmental conditions by preserving layers of sediment or rock over time. Scientists can analyze these samples to understand past climates, ocean conditions, and even the presence of certain organisms, helping to reconstruct Earth's history and track changes over time.
What happens to the sediment that is carried by water?
Sediment carried by water can be deposited along riverbanks, in lakes, or the ocean, forming sediment layers. It can also be transported over long distances and eventually settle at the ocean floor. Sediment can impact aquatic ecosystems, increase turbidity, and contribute to erosion.
What are the 2 pieces of equipment used to collect bottom samples on the HMS Challenger?
sounding weights used on the Challenger, called Baillie sounding machines, were provided with a tube into which a sample of the seabed was forced when the weight hit the bottom of the ocean. Also used on the Challenger were dredges and scoops, suspended on ropes, with which samples of the sediment and biological specimens of the seabed could be obtained.
Deltas are formed by the accumulation of?
sediment carried by rivers as they flow into a body of water, typically an ocean or a lake. This sediment builds up over time, forming the distinctive triangular shape of a delta.
How do core samples along the ocean floor help to explain tectonic movement?
Core samples would reveal that the further from the mid-ocean ridge you go, the greater the overlying sediment on top of the basaltic crust. This would indicate that the crust closer to the ridge was younger and more recently formed. The creation of new crust at mic-ocean ridges is the crucial evidence for the movement of tectonic plates.
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.
What are the core top samples in marine geology?
In the deep ocean, the initial core sample layer would consist of a pasty ooze, unlithified, consisting mainly of organic matter. After that, it would pretty much be basalt, an igneous rock.

What type of sediment represents a relatively small portion of the overall sediment in the ocean?
hydrogenous
How does sediment that is closer to a mid ocean ridge compare to sediment that is farther away?
it is older
As rivers flow into the ocean and deposit thick layers of sediment on the ocean floor what will the crust under the sediment do?
the crust will cool to form metamorphic rock
How does sediment that is closer to a mid ocean ridge compare to sediment that is father away?
It's thinner
What is an ocean floor sediment?
broken up rocks
What is a narrow column of sediment found in the ocean?
United
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. :)
