Step 1
According to the theory of plate tectonics, the motions of earth's lithosphere or outermost layer of hard, solid rock, has moved over geologic time. This theory provides scientists with great deal of information about the regions past. The polar region was formed when the Earth's lithosphere was broken into seven major and many minor tectonic plates. These plates move in relation to each other, slowly changing the location of earth's continents and oceans. There is evidence that North American and Antarctica were connected approximately one billion years ago in the global supercontinent Rodinia. The continents broke apart and merged again 200 million years ago in supercontinent Pangaea. Antarctica was connected to South America. According to the theory of tectonic plates there was considerable volcanic and seismic activity in the movement of tectonic plates.

Step 2
The theory of plate tectonics describes the ...
