Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
What happens when the ocean crust sinks deeper inyo the mantle?
It melts and becomes magma.
What is the ocean bottom called?
The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. These areas are called deep sea trenches and the Challenger Deep in the Mariana Trench in the Pacific is the deepest known point in Earth's oceans.
What is subuction?
subduction is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
What is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary called?
This process is called subduction.
What is the process by which ocean floor sinks into the mantle?
subduction is the answer.

When water gets denser how does it move?
I think it sinks toward the ocean floor.
Where oceanic crust sinks toward the mantle beneath continental crust a deep ocean?

If a mass of ocean water is cold and salty what will it do?
The cooler saltier water sinks toward the ocean floor.
True or false magnetic stripes on the ocean floor are places where oceanic crust sinks back to the mantle?

Is magnetic stripes on the ocean floor the places where oceanic crust sinks back to the mantle?
it is right in your book soo... you should be able to answer this
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.
A deep valley along the ocen floor beneath which oceanic crust slowly sinks toward mantle?
This is known as a trench in a subduction zone.
What is the process called when the sea floor sinks into the mantle?
Subduction.
