How Pangea Changed.

This is a picture of what Pangea looked like, and how it changed over time.
  • The first picture shows what the world looked like 250 million years ago, when it only had one continent named Pangea. Pangea was one huge continent in which all the countries were united together to form it.
  • The second picture shows Laurasia, and Gondwanaland. This took place about 200 million years ago. These two Continents were formed, because Pangea started to separate due to the movement of plate tectonics. Gondwanaland included South America, Africa, India, Australia, and Antarctica. And Laurasia included North America, and Eurasia.
  • The third picture takes place about 135 million years ago, plate tectonics moved even more, and separated the countries a lot more.
  • The fourth picture is what the world looked like about 45 million years ago, where countries were so far apart, that most of them weren't connected to each other anymore.
  • The last picture is a picture of the world today. Today, the world is made of seven different continents: North America, South America, Asia, Antarctica, Europe, Africa, and Australia.
