University of Phoenix Material Effects of the Motions of Tectonic Plates Worksheet From Visualizing Earth Science, by Merali, Z., and Skinner, B. J, 2009, Hoboken, NJ: Wiley. Copyright 2009 by Wiley. Adapted with permission. Part 1 This diagram was similar to one Alfred Wegener drew to show the distribution of continents 300 million years ago. His theory of continental drift was met with skepticism in the scientific community. [pic] 1. Describe three forms of evidence Wegener used to support his ideas of continental drift. Wegner suggested that the continental shelves of the continents seemed to fit together similar to a puzzle. According Bugielski (1999), "continents in the southern hemisphere exhibit an…show more content…
Questions were raised when rocks were found on the surface of the Earth that had manetization the did not corralate to the location that it was found. Also, Harry Hess suggested that the continents could have drifted and still were because the sea floor was moving much like a conveyor. (Bugielski, 1999). Bugielski, M. (1999).

Discuss in detail the two pieces of additional evidence that supported Wegener’s theory, now known as the theory of plate tectonics. Part 2 Write paragraph answers to the following questions using what you have learned from Visualizing Earth Science and the assigned WileyPlus® GeoDiscoveries®. 1. How does the motion of the tectonic plates affect the climate? It is thought that the change in ocean currents is caused by plate tectonics generating more heat. It is said that the increased volcanic eruptions from plate tectonics causes a greater release of carbon and sulfur dioxide into the atmosphere. This raises the temperature around the world.
