It was concluded that hot rock from the mantle was rising up through the lithosphere and pushing the sea floorâand the continents on either sideâapart. This finding provided the mechanism to explain the purposeful movement of Earthâs plates and led to the development of the first theory of plate tectonics. Today Cooper is among a new generation of geologists who study what could be called âpostâ plate tectonics. Taking the field up a notch, she investigates similar processes on other planets and asks why Earth has plate tectonics in the first place.
The plate tectonic theory known today evolved in the 1950s, owing to four major scientific developments: 1  Demonstration of the young age of the ocean floor; 2  Confirmation of repeated reversals of the Earth's magnetic field in the geologic past; 3  Emergence of the seafloor-spreading hypothesis and associated recycling of the oceanic crust; and.
