Is it possible that the continents were actually together sometime in the past? Continental Drift Theory
Alfred Wegener’s Theory of Continental Drift Theory that continents can drift apart from one another and have done so in the past. Reasons for theory: –The continents seem to fit together like puzzle pieces. –Fossils of the same plant and animal species are found on several continents across oceans. –Glacier grooves match theoretical placement.

Sea-Floor Spreading Takes place at Mid-ocean ridges (Mountains in the middle of the ocean)
New Oceanic Lithosphere is Created
Magnetic Reversals blah
Possible Causes of Plate Motion Blah
Tectonic Plate Boundaries Convergent, Divergent, & Transform
Tracking Tectonic Plate Motion Scientists use a network of satellites called the Global Positioning System (GPS) to measure the rate of tectonic plate movement.
