In 1915, Alfred Wegener proposed his continental drift theory. He said that the continents floated atop the mantle, a heavier, dense layer of rocks deep within the earth. Wegener predicted that heat rising within the hot mantle created currents of partially melted rocks that could move the continents around the earth’s surface. Like many revolutionary theories, Wegener’s was not initially accepted by scientists.

In the late 1960's, data revealed an alternating striped pattern of seafloor rocks. Rocks that formed when Earth’s magnetic field was in one position alternated with rocks that formed when the field was reversed. The stripes ran parallel to the mid-ocean ridges and extended out hundreds of miles on either side. The seafloor’s permanent magnetic signatures showed that new ocean crust was created at the ridge crests and then spread outward in both directions.

Elaborate on the 1960's discovery. Does this support or contradict Wegener's theory?
