How is new rock added to the ocean floor?
New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.
What is the process of the ocean floor sinking beneath a deep ocean trench and back into the mantle known as?
The process of the ocean floor sinking beneath a deep ocean trench and back into the mantle is known as subduction. This occurs at convergent plate boundaries where one tectonic plate is forced beneath another due to differences in density. Subduction zones are associated with volcanic activity and the formation of mountain ranges.
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called?
That is a description of a trench, which is formed at tectonic plate boundaries where one plate is forced beneath another through a process called subduction. Trenches are among the deepest parts of the ocean floor.
Why do scientists look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.
What is the process that continually adds new material to the ocean floor is called?
sea-floor spreading
What is the process called In which the ocean floor sinks into the mantle called?
i think that its subduction ...
As the ocean floor spreads other parts plunge into the mantle What is this process called?
subduction
IF the ocean floor spreads other parts plunge into mantle this process is called?
Subduction .
What is the process by which ocean floor sinks into the mantle?
subduction is the answer.
What is the geological process by which the ocean floor sinks into the mantle?
subduction
As the ocean floor spreads other parts plunge into the mantle--this process is called?
The first process is called sea-floor spreading (rifting when it happens on land) and the second process is called subduction. Both processes are part of plate tectonics.

A long narrow and very deep canyon where the ocean floor bends toward the mantle is called what?
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.

A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
What process is shown occurring at C and what does it occur?
In a process taking tens of millions of years, part of the ocean floor sinks back into the mantle at deep ocean trenches.
