Today and yesterday we learned about Alfred Wegner and his theory years ago. His theory was that Africa and South America were once conjoined. He found this out because He was looking at some old maps and found that they fit together like a puzzle. Many people didn't belive him, but he proved he was right with a thing called "The Continental Drift". It's when the earth's continets move so slowly. We can't feel it though, but the earth is constantly moving. Long ago all the continets were conjoined and were called "Pangaea". It was a supercontinent. Another thing Alfred Wegner found was that fossils from one place matched the other in a different place. It was very interesting to hear about! To learn more, visit this site!
