Blog Post #3

Check out this timeline of plate motion. The first map that you see is present day. Scroll down to Rodinia (750 million years ago). Each map as you go up is later on the timeline (see the numbers on the right side of the screen). Answer the following questions in your blog:

1. How were Rodinia and Pangaea similar and different from each other?
2. When did the tectonic plates appear to move the fastest? (biggest difference between two consecutive maps)
3. Look at Pangaea (250 million years ago). If the continents looked like Pangaea today, what would the world be like? Think about governments, sports teams and leagues, and other aspects of life.
4. Look at Pangaea. If you could pick any place in Pangaea to start a modern civilization, where would you pick? Why? (there is a key on the bottom of the page that explains what the little letters in the maps stand for. For example, "ar" means Arabia.)
