The Aged Earth


1. How were Rodinia and Pangaea similar and different from each other?
The Rodinia had more space in between therefore not making the one continent. The Pangaea had almost all of the land together as one. Though the both split up farther apart over time.

2. When did the tectonic plates appear to move the fastest? (biggest difference between two consecutive maps)
From the 150 and 80. They seemed to have the biggest difference when the moved.

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.
Well, there are ups but there are also downs. We may not be able to grow different types of plants that are needed for food. We may not have as much states and countries if we were joined together. Also, depending on the country this could be both good and bad, you can invade for land easier. Traveling would also be easier.

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.)
I would choose Africa because there is a fair amount of land which gives you more places to build for a better economy. Though you would need enough people willing to be in the military so you can be protected from invastions. You can grow a fair amount of plants also to help the ecomony so people could have more food. Where the continent is located would give you a small, but choice, of the climate you may want to live in.

Going through Earth

1. The deepest mine was about 2 meters.


2. You would have to dig 6, 378km to get to the mantle.


3. The crust was easy to get through and wasn't too hot. The mantle would probably be an orangey red and liquid. Though it wouldn't be too liquidy it would be like silly putty. It would begin to get hotter and thicker as we kept digging. When we reached the outer core it would be thicker, feeling strictly like spoiled milk, than when we first reached the mantle. It was a little darker color than the mantle was. When I finally reached the inner core it was extreamly hot getting hotter and hotter as I went through. It was very thick and was very hard to move through. It was a dark red and the gravity of it felt like it was pressing down on us. Barely able to walk through the thickness we reached out into the outer core again. Finding it easier to move we slowing started making out way back to the surface. When we finally got to our destination people looked at us weird because we were covered from the inside of Earth.
