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.


What is the most abundant mineral in the ocean floor?

The most abundant mineral in the ocean floor is likely to be olivine, which is a common mineral found in basaltic rocks that make up the oceanic crust. Olivine is a magnesium-iron silicate mineral that is formed from the cooling and solidification of magma at mid-ocean ridges.


Where are the youngest rocks on the ocean floor typically found?

fault line


Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?

Ocean-floor rocks and sediments show a pattern of symmetric age distribution, with younger rocks near mid-ocean ridges and older rocks farther away. This supports the theory of seafloor spreading, where new oceanic crust is created at mid-ocean ridges and spreads away from them. As the crust moves, it picks up and records the magnetic signature of Earth's magnetic field, creating alternating magnetic stripes that are evidence of seafloor spreading.


Explain how the ages of the rocks on the ocean floor support the theory of seafloor spreading?

Sea floor spreading, a theory thought up by Harry Hess in the late 1950s, was drawn up in relation to the differing ages of rocks which make up oceanic crust (ie the ocean floor). The ages of rock on the ocean floor support this theory because of the fact that the youngest rocks are found at the mid-oceanic ridges, where constructive plate margins are found. The oldest rocks are found at the fringes of the ocean-continent boundary. This supports the idea because it shows that when magma rises and cools at the boundary, and creates new rock. This rock is then fed in a conveyor belt-like method to the edges of the oceans, where they are then subducted under continental crust as a part of destructive plate margins. This means th oldest rock is found at these boundaries. Hope this helps :)
