A rock plate that sinks back into the mantle is called a subducting plate. This process occurs at convergent plate boundaries where denser oceanic plates sink beneath lighter continental plates.
The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary is called subduction. This occurs because oceanic crust is denser than the underlying asthenosphere, causing it to be pulled down into the mantle. Subduction zones are associated with the formation of volcanic arcs and deep-sea trenches.
A "subduction zone".
The process is called subduction. Subduction occurs at convergent plate boundaries when one tectonic plate moves beneath another and sinks into the mantle. This process is crucial for the recycling of Earth's lithosphere.
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.
When an oceanic plate collides with a continental plate, the denser oceanic plate is forced beneath the continental plate in a process called subduction. This creates a deep oceanic trench. As the oceanic plate sinks, it heats up, melts, and forms magma that rises to the surface, leading to volcanic activity.
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.

, hot material rises towards the surface and cooler material sinks back down towards the Earth's core. This is called mantle convection and is driven by the heat generated from the Earth's core and the heat released from radioactive decay within the mantle. The motion of these convection currents is responsible for plate tectonics and the movement of continents over time.
The force driving plate movement is mainly attributed to the heat from the Earth's interior. As plates move apart at mid-ocean ridges, hot magma rises from the mantle, creating new crust. Subduction zones occur where plates converge, and the colder, denser plate sinks back into the mantle, initiating the process of melting.
