Later studies of the oceans provided one of the keys to the plate tectonic theory.
For other divergent plate boundaries on earth.
Plate tectonics the theory that the earth s lithosphere consists of large rigid plates that move horizontally in response to the low of the asthenosphere beneath them and that interactions among the plates at their borders cause most major geologic activity including the creation of oceans continents mountains volcanoes and earthquakes.
