When the earth cools because it does not have enough radioisotopes left in the mantle and core to keep them hot enough to drive mantle convection.
As far as the Earth is concerned - plate tectonics has not stopped; the plates are still in motion - which is why we get earthquakes and volcanic eruptions along the plate boundaries.
Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.
Plate tectonics
plate tectonics
yes it represets plate tectonics
instruments used in plate tectonics?
Yes, the singular form is normally plate tectonic or tectonic plate so the plural would be plate tectonics or tectonic plates. Dumb crap.
That's like saying, if the world didn't exist would we still have oceans? You can't really get rid of plate tectonics so it doesn't really mean anything.
how are volcanoes and the process of plate tectonics related
the branch of geology for plate tectonics is asthenosphere.
But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.
Question is too broad. How do they help what? Are you asking how plate tectonics WORK?
