Scientists of Tectonic Plate Theory

Chloe, Claudia, & Kaytlynn :)

Abraham Ortelius 1570-1612

"Abraham created the first world atlas. It was so successful they made four copies in the first year. They also made fourty-two editions, & they were all in 7 different languages, Latin, German, Flemish, French, Spanish, English, & Italian." This theory is important because if it weren't for Abraham, Wegener wouldn't of started the idea of the continental drift.

James Hutton 1788

James created the Theory of Uniformitatridnism. His evidence for the hypothesis or theory was by studying the Devonian Old Red Sandstone he discovered Sedimentary Rock was formed by multiple floods. This theory is important because Uniformitatridnism is one of the fundamental principles of earth science. "James Hutton is also known as the founder of modern geology."

Alfred Wegener 1915

Alfred Wegener created the Theory that the continents were once all together. His evidence for the hypothesis or theory is the plants & animals couldn't of moved across the sea, so it proves they were all once together. This theory is important because he was the first person to challenge the world by saying the earth didn't work the way they thought it did. "Alfred Wegener was a meteorologist (a scientist that studies weather) before he became a geologist."

Harry Hess 1962

Hess's theory was that he thought that the sea floor was spending through vents in the rift where hot magma oozed up. He found evidence through the youth of the ocean floor, presence of island ares,deep sea trenches and the origin of the mid-ocean ridge. His discovery was important because it was the final proof needed to prove that Pangaea existed. After Hess died in 1969 Arthur Holmes expanded Hess's theory to come up with convection cells in the mantle.

Dan McKenzie 1967

Mckenzie's theory was that he thought the mantle is what moves the plates and it is called "continental drift". He found evidence by conducting research in Iceland to find how magma flows and comes to the surface. His discovery was important because it showed the earth was more dynamic then we thought it was.
