Why recycling is used to describe the process of the tectonic plates?
Crustal recycling is a tectonic process by which surface material from the lithosphere is recycled into the mantle by subduction erosion or delamination. Identification of this crustal signature in mantle-derived rocks (such as mid-ocean ridge basalts or kimberlites) is proof of crustal recycling.Click to see full answer.

Crustal recycling is a tectonic process by which surface material from the lithosphere is recycled into the mantle by subduction erosion or delamination. Identification of this crustal signature in mantle-derived rocks (such as mid-ocean ridge basalts or kimberlites) is proof of crustal recycling.Click to see full answer. Similarly, it is asked, why is recycling a good description of plate tectonics?Continental crust has been created and destroyed throughout Earth’s history. Relatively small amounts of continental crust are recycled back into the mantle as the tectonic plates collide, through subduction and erosion of continental material. Subduction is also a driver for plate tectonics.Secondly, how does density play a role in plate tectonics? When two plates come in contact with each other through plate tectonics, scientists can use the density of the plates to predict what will happen. Whichever plate is more dense will sink, and the less dense plate will float over it. The exact result depends on which types of plates are interacting. People also ask, what forces drive tectonic plates? The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones) How does plate tectonics recycle and create new crust on the planet?Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth’s mantle. Seafloor spreading creates new crust.
