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.
usually from lava sinking to ocean floor and cooling.
No. Oceanic crust is recycled into the mantle through a process called subduction and new ocean floor is formed at mid-ocean ridges. None of the ocean floor is more than about 180 million years old. Some rocks on the continents are billions of years old.

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 down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
In a process taking tens of millions of years, part of the ocean floor sinks back into the mantle at deep ocean trenches.
