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 ...

Paleogeography, Evolution of orogenic belts, Climate

I need help writing an essay on two of the following, but can't decide which. Also - I need detailed explanations in layman's terms, while showing me how to use appropriate scientific language when describing the events -
1. Paleogeography: Changing paleogeography, both globally ("Dance of the Continents") and for North America.
2. Evolution of orogenic belts (mobile belts), their role in changing continental geographies and the plate tectonic actions responsible.
4. Climate: The events and patterns of climate change and their possible explanations especially those that shed light on the modern climate issues.

My essay has to examine the evolution of the features included in the themes, and will relate events and features of your my chosen themes to one another. If you could show me what this would look like in 1-2 pages, that would be great.
Thanks!
