What happens to old oceanic crust as new molten material from the mantle?

What happens to old oceanic crust as new molten material rises to the mantle?

What happens if an oceanic to oceanic happens?
When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. The subducted plate sinks down into the mantle and begins to melt. Molten rock from the plate rises toward the surface and forms a chain of volcanic islands, also called a volcanic island arc, behind the trench in the ocean.
What is the mantle's materials?
It's very high temperature down in mantle so it resulting a solid rock to change into "molten" state. The molten material in the mantle is magma.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
In sea-floor spreading what happens to the old oceanic crust as new molten material rises from the mantle?
In sea-floor spreading, the old oceanic crust is pushed away from the mid-ocean ridge as new molten material rises from the mantle. As the new material solidifies, it forms new oceanic crust, leading to the spreading of the seafloor and the continuous creation of new crust. The older oceanic crust eventually gets subducted back into the mantle at tectonic plate boundaries.
Describe how molten rock can form new oceanic crust?
Some of the molten rock overflows onto the ocean floor in tremendous eruptions. material from the mantle canwell up, forming a ridge and new oceanic crust.
What happens when oceanic crust sinks?
When oceanic crust sinks into the mantle at a subduction zone, it melts due to the high temperature and pressure. The molten rock then rises to the surface, forming volcanoes on the overriding plate. This process helps to recycle material back into the mantle and plays a crucial role in plate tectonics.
What happens to the crust when the molten rock sinks to the lower mantle?

What are molten material in the mantle?
Yes. The mantle is composed of the plastic mantle, or the upper part, which is partially molten. The stiffer mantle is under it. it is not as molten
Is it true the mantle is completely molten?
no. the mantle is only partially molten
