The Continental Debate
Continental Drift, Seafloor Spreading, Plate Tectonics
Earth 100 Million Years From Now
Continental Drift Summation
I believe that Continental Drift is real. Just by looking at Africa and South America, you can tell they look like that they fit together for it to be coincidence. How else would you explain having fresh water reptiles in different continents, divided by the Atlantic. With out the continents moving, how would there be tropical plants in cold climates, or glaciers in the tropics? Rock structures in Eastern U.S. and Western Europe were just too similar for coincidence. I believe they are moving because of plate tectonics and convection currents (see Plate Tectonics Summation).
Sea Floor Spreading with Bill Nye
Sea floor Spreading Summation
I believe in sea floor spreading. The magnetic pole reversals are evidence of seafloor spreading. As you start at the mid-ocean ridge and move outward, the rock in the seafloor points to the magnetic north of the time. The rocks now show the reversals in magnetic north at regular intervals showing seafloor spreading over time. Except that the current magnetic north is overdue for a change and may happen at any time.
Plate Tectonics Summation
I believe that Plate Tectonics is plausible. Based on what I have seen, heat has the ability to move objects. The rest of the Earth, being many times larger than the crust, could easily produce enough heat to move the crust. It is also a logical explanation for the geological and seismic activity that takes place on the crust.
