However, while this means that the tectonic plate is dying, the researchers said that it will take at least a few million years for it to completely "die."
An empirical test to determine the dominant mechanism driving tectonic plate motion out of mantle convection, ridge push and slab pull involves plotting the percentage of a plate's boundary that is divergent and subducting under another plate against the speed of the plate.
Part of the global mid-ocean ridge system that encircles the planet, these regions generate 70% of the Earth's tectonic plates. However, because the chains of volcanoes lie more than a mile beneath the sea surface, scientists know little about them.
