What was the earth called when all countries were joined together?

Answer 1

The name off all the continents joined together is Pangaea they were joined together more than 200 million years ago and started to drift apart due to the tectonic plates in the earths core. They are constantly moving apart. However we know that they were all joined together because fossils that were discovered in china are also being discovered in North America this is because dinosaurs used to walk over continents. The same soil and rock is being discovered in different parts of the world e.g. south America and Africa. Also we can tell this because if you draw it like a jigsaw puzzle you can see that south America and Africa join together. The pipelines going from America and England are also being pulled apart as the plates move further away from each other. India broke off from Africa and drifted apart until it crashed into Asia and the crash was so massive the Himalayan mountains were produced. India is still today moving more into Asia causing the mountains to grow bigger. This is proof that the continents once used to be joined together as one country called Pangaea.
