Abraham Ortelius
Theory:
-Continental drift
Evidence:
-South America and Africa looked like they fit together
-Similar fossils and species in different continent
Accepted or not:
-No because he didn't have strong evidence -
James Hutton
Theory:
-Uniformationarian principle
Evidence:
-Catastrophic processes were not responsible for the landforms
Accepted or not:

Alfred Wegener
Theory:
-Continental drift
Evidence:
-Continents looked like they could fit together
-Similar rock formations on different continents

Accepted or not:
-Not accepted because he had no proof of the drift -
Arthur Holmes
Theory:
-Convection Currents
Evidence:
-The mantle undergoes thermal convection
Accepted or not:
-disagreed because it wasn't a widely known theory -
Harry Hess
Theory:
-Seafloor spreading
Evidence:
- Mid-ocean rides
-the deepest parts of the ocean were very close to continental margins
Accepted or not:
-Yes because it went along with Alfred Wegener ideas -
Frederick Vine
Theory:
-Earths surface is split into plates
Evidence:
-the seafloor spread from mid-ocean ridges with a symmetrical pattern of magnetic reversals in the basalt rocks
Accepted or not:
-Agreed because it explained alot about the issues of the seea floor -
Drummond Hoyle Mathews
Theory:
-Seafloor spreading
Evidence:
-Magnetic stripes on the side of ridges on the ocean floor
Accepted or not:
-Agreed because he had good evidence -
Lawrence Morley
Theory:
-Continental drift
Evidence:
-Magnetic patterns in rocks
Accepted or not:
-Yes because he had good evidence
