Pangea and Continental Drift
A German scientist named Alfred Wegner formed a hypothesis that 300 million years ago, all the continents were joined together and have since drifted apart. He named this supercontinent Pangea, which means "all lands". Wegners idea came to be known as continental drift. He's also used continental drift to explane why montaions are formed. He stated that, as continents collide, their edges crumple and fold, pushing up huge chunks of rock to make mountains.
Landforms: Mountaon ranges in South America and Argentina lined up. Euorpean coalfields and coalfields in North America.
Fossils: Identical fossils found in places now seperated by oceans Glossopteris, fossils of a fernlike plant was found in Africa, South America, India, australia, and antartica but its seeds couldnt have traveled across distances that now seperated the continents.
Climate: Fossils of tropical plants found on islands with polar climates. Evidence of glaciers found on contentins with tropical climates.
Sadly, wegners theory was rejected because he couldnt explain the force that pushed and pulled the continents.
