Alfred Wegener– Continental Drift

Alfred Wegener has proposed the idea the all the continents were once combined into one super continent called Pangaea. Over time the continents have moved do to “continental drift” and have formed the world that we have today. Evidence of the same fossils has been found on my continents proving that Wagner’s theory was true.

Harry Hess- Sea Floor Spreading

Harry Hess has proposed the idea of sea floor spreading is magma coming up from the ocean, and pushing continents apart. The older crust lies farther away from the part where the spreading starts. The youngest lies closer to the part where the spreading starts. Some of the continents are where they are today because of sea floor spreading. The continents only move about 5 cm. per year.

Plate Tectonics

The Earth is broken up into different pieces called tectonic plates like a “jigsaw puzzle” The tectonic plates move from convection currents in the Asthenosphere. Sometimes the movement causes earthquakes or the plates collide causing mountains.
