Abraham Ortelius
He first came up the Continental drift theory. His evidence was that the Americas, Europe and Africa fit together like a puzzle. -
Alfred Wegener
He suggested that all the continents where once together to make a super continent he named it Pangaea.Wegener believed that Pangea’s constituent portions moved thousands of miles apart over long periods of geologic time. His idea was rejected because he couldn't describe what forces where making the continents move. -
Arthur Holmes
He proposed that the convection in the mantle was firing the continents to drift. Using Wegener's theory he started to use the radioactive dating to find out information about rocks and minerals. His theory was accepted because he was able to show what Wegener couldn't. -
Harry H. Hess
He developed the idea that the oceanic crust forms along the mid-ocean ridges and spreads out laterally. He started this when a new mechanism was created and from Wegener's theory. -
Frederick J. Vine
Vine and two other scientist that worked from others research said that the new crust would have a magnetization aligned with earths geomagnetic field. They noted that this would appear over time as geologic time as brands of the crust. Their theory was accepted because they where able to expand past geologist theories. -
Lawrence Morley
Morley's theory was that the ocean floor was imprinted with the record of the direction and intensity of earths magnetic field. He based his theory on the highly speculative theory on the oceans survey that alternats bands of magnetism in the oceans crust. His theory was rejected because it supposedly wasn't the sort of thing to be published under serious scientific aegis. -
Drummond Matthews
His theory was that the crust near the mid-ocean ridges was composed of streaks suggesting that the magnetic polarization of the theory of the seafloor spreading. His theory was shared with Vine and Morley and their theories where either accepted or they weren't. -
John Tuzo-Wilson
He discovered the theory on conservative plate boundaries that transform faults were regarded as missing pieces of a puzzle. This allowed plates to slide past each other without an oceanic crust being created pr destroyed.
