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.
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.
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
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.
the asthenosphere and the lithosphere contain molten material.
The upper part of the mantle, known as the asthenosphere, contains molten material. This region is partially molten, allowing for the movement of tectonic plates. Deeper parts of the mantle, such as the lower mantle, contain solid rock due to higher pressures and temperatures.
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.
Yes, molten material does erupt inside the central valley of mid-ocean ridges. This molten material comes from the Earth's mantle and rises to the surface through the cracks in the oceanic crust, creating new crust as it solidifies.
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.
