Webb22 mars 2012 · In 1960, Harry Hess proposed that the movement of the continents was a result of sea-floor spreading. He hypothesized that the sea-floor was spreading from vents in the Great Global Rift, where hot magma oozed up. As the magma cooled it forced the existing sea-floor away from the Rift on either side.

WebbThis process, called sea-floor spreading, continually adds new material to the ocean floor. Scientists have found strange rocks shaped like pillows in the central valley of mid-ocean ridges. Such rocks can form only if molten material hardens quickly after erupting under water. The presence of these rocks supports the theory of sea-floor spreading. WebbSeafloor spreading is a natural geologic process that separates large tectonic plates from the Earth’s lithosphere. The evidence behind seafloor spreading supports continental drift theory.
