11/20/13 Earth Space Science Plate Tectonics Theory Plate tectonics is the theory that the outer rigid layer of the earth is divided into a couple of dozen plates that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. Plate Tectonics is cause by convection currents in the mantle of the Earth. This theory was originally called continental drift. The theory of “Pangea” that is the continents were connected was Alfred Wegener. The age of the sea floor is

sedentary lifestyle” (“Some People”). Not all people have the same ability to turn down food whenever they want. That causes people to be overeaters‚ thus‚ making them overweight. However‚ not only can some people be genetically predisposed to overeat‚ but most Americans have a different mindset in their eating choices.

A plate tectonic is defined as a solid rock mass that builds up the Earth’s surface. The plate tectonic theory is a theory that geologists use to help explain the surface processes and events. The word plate means large pieces of the earth that are always in motion‚ lithosphere plates. Tectonics means how the continents formed and move over time. This is the theory that most geologists accept as to what happened to our continents. It states that Earth is made up of two layers‚ the lithosphere
