8. Theory: Uniformitarian Principle of Plate Tectonics: This principle is commonly stated as follows: The present is the key to the past. Those holding this viewpoint assume that the geologic forces and processes -- gradual as well as catastrophic -- acting on the Earth today are the same as those that have acted in the geologic past. (1785) James Hutton= Known as the Father of Geology

9. (1596) Abraham Ortelius Book: Thesaurus Geographicus ; linked with Theory of Plate Tectonics In 1575 was a geographer and map maker for the king of Spain. Ortelius suggested that the Americas were "torn away from Europe and Africa... by earthquakes and floods" and went on to say: "The vestiges of the rupture reveal themselves, if someone brings forward a map of the world and considers carefully the coasts of the three [continents]."

10. (1912) Alfred Lothar Wegener Theory of Continental Drift: He contended that, around 200 million years ago, the supercontinent Pangaea began to split apart into the continents of Laurasia in the northern hemisphere and Gondwanaland in the southern hemisphere. These continents then split in the smaller continents of today. Evidences that were used to prove his theory were: rocks, climate, and fossils.

11. (1953; 1960) Harry Hass Linked with Theory of Plate Tectonics, Sea- Floor Spreading With the discovery in 1953 of the Great Global Rift, a volcanic valley running along the midocean ridges, Hess looked back at data he had collected during the war.Great Global Rift In 1960 (and with further elaboration in 1962), he hypothesized that the sea-floor was spreading from vents in the Rift, where hot magma oozed up. As the magma cooled it forced the existing sea-floor away from the Rift on either side.sea-floor was spreading This theory accounted for and united several separate puzzles in marine geology: the youth of the ocean floor, the presence of island arcs, the deep sea trenches, and the origin of the midocean ridges.

12. (1930) Arthur Holmes Principal of the Theory of Continental Drift: Suggested a mechanism that could explain Alfred Wegener's theory of continental drift: the power of convection. Currents of heat and thermal expansion in the Earth's mantle, he suggested, could force the continents toward or away from one another, creating new ocean floor and building mountain ranges.

13. (1799) Alexander von Humbolt Principal of Theory of Continental Drift: Embarked on a 5 year expedition in South America, where he accumulated much information about plant and animal life, and landforms. During this trip, he realized that the similarities of Africa and South America went beyond that of an apparent 'fit' of their coastlines. Several mountain ranges that seemed to end on South America's eastern coast resumed on the western shores of Africa, and there were striking resemblances between the geological strata of the 2 continents - the mountains of Brazil, for instance, were the same as those of the African Congo.
