Abraham Ortelius Theory
His theory was of continental drift, that all continents over time drifted apart, similar to Alfred Wegener, his only evidence was that all the continents seemed to fit together. Scientists disagreed with him because there was not much evidence -
Continental Drift Theory
Alfred Wegener introduced this theory in 1915 and his hypothesis was that all continents were once joined together but over time they drifted apart. His evidence was that the continents all fit together like puzzle pieces, he also used climate clues, and fossil clues to support his theory. Nonetheless, his theory was not accepted by the scientific community, since he did not have much evidence to back it up. -
Arthur Holmes Theory
He proposed that Earth's mantle contained convention cells that dissipated radioactive heat and moved crust at the surface. the seafloor-spreading theory supported this, and Harry Hess's theory also did. His theory was agreed on since it provided a potential explanation for continental rifting -
Harry H. Hess Theory
His theory talked about plate tectonics and how hot magma would rise from under the crust at the Great Global rift. His evidence was of how hundreds of flat-topped mountains shape the pacific floor. scientists disagreed with him because there was not enough evidence -
Frederick plate tectonic theory
His theory was of plate tectonics that the seafloor spreads from mid-ocean ridges with asymmetrical pattern of magnetic reversals with basalts. He used Robert S. Dietz theory as evidence to support his. He also studied how mid-ocean ridges were formed. Initially it was not well-recieved since he needed further evidence -
Sensors
A global network of sensors designed to detect hydroacoustic signals was installed to a ship called Nuclear-Test-Ban-Theory of 1963. Scientists agreed with this because they found it very useful -
Glomar Challenger vessel
The vessel set sail to explore the mid ocean ridge South America and Africa. Core samples obtained from drilling revealed that rocks close to mid-ocean ridges are younger than rocks that are farther away from the ridges. -
Frederick-Morley-Matthew theory
The three of them worked together to find out that new crust would have a magnetization aligned with Earth’s geomagnetic field. The later identification of such patterns of magnetic striping provided additional evidence that Earth’s plates separate at mid-ocean ridges. Scientists agreed with this theory because they found it reasonable
