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?
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.
What are places where oceanic crust sinks back into the mantle called?
A "subduction zone".
What is the process called when the oceanic floor sinks into a trench and back into the mantel?
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.
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 when an oceanic plate collides with a continental plate and sinks?
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.
What happens at oceanic-oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
What happens at an oceanic- oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.

What is the name of the process where ocean crust sinks back toward the mantle?
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.

In the Earth's mantle heat is transferred in large convection currents. Within these currents?
, 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.
What drives plate movement by pushing rock back into the mantle where it melts?
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.
