Abraham Ortelius
Theory: Abraham Ortelius had a theory that the continents could have previously been connected. Evidence: His evidence was that the continents seemed to fit perfectly when put together like a puzzle. Did scientists agree or disagree?: Scientist disagreed with this theory because he didn't have enough evidence to support his claim. -
Alfred Wegener
Theory: Alfred Wegener had a theory that the continents moved from a super continent called Pangaea. Evidence: When put together similar to a puzzle, the continents seem to fit together almost perfectly. Did scientists agree or disagree?: Scientist disagreed because Alfred Wegener didn't have enough evidence to show how the continents moved. -
Arthur Holmes
Theory: Convection could explain continental drift. Evidence: The Earth's mantle undergoes thermal convection. Did scientists agree or disagree?: Scientists disagreed with his theory because he didn't have much evidence to support it. -
Robert S. Dietz
Theory: Seafloor spreading Evidence: He discovered a fracture zone in the Pacific which explained the deformation in the Earth's crust. Did scientists agree or disagree?: Scientists agreed with his theory because he had good evidence that included maps. -
Harry Hess
Theory: Seafloor spreading Evidence: He identified the presence of mid ocean ridges. He also discovered that oceans were shallower in the middle and that the deepest parts of the ocean were very close to continental margins. Did scientists agree or disagree?: Scientists agreed with his theory because he had evidence to support his theory and it supported Alfred Wegener's theory. -
Frederick J. Vine
Theory: Frederick J. Vine had a theory that there are blocks of ocean crust that contain magnetized rocks. Evidence:His evidence was a detailed magnetic survey that proved his theory to be correct. Did scientist agree or disagree?: Scientists agreed with this theory because there were many scientists who discovered the same thing and because Frederick J. Vine had good evidence. -
Drummond Hoyle Matthews
Theory: Seafloor spreading Evidence: There are magnetic stripes on the sides of ridges on the ocean floor. Did scientists agree or disagree?: Scientists agreed with the theory because his evidence and evidence from other scientists supported his theory. -
Lawrence Morley
Theory: Continental drift Evidence: He discovered a magnetic pattern of igneous rock on the ocean floor. Did scientists agree or disagree?: Scientists agreed with his theory because he always came up with new evidence with new technology.
