WebHolmes primary contribution was his proposed theory that convection occurred within the Earth's mantle, which explained the push and pull of continent plates together and apart. He also assisted scientists in oceanographic research in the 1950s, which publicized the phenomenon known as sea floor spreading. Soon after in the 1960's the theory of ... WebThe mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler it sink down.
