Study Notes
- Pangea was a supercontinent that existed around 280 million years ago.
- The Earth's crust consists of several plates that move slowly, causing significant changes over millions of years
- Pangea is derived from Greek, means "all lands".
- Pangea: all continents were joined together as one giant landmass.
- Back then the Earth had continents in different locations.
- There was only one big ocean called Panther Lassa.
- Plate tectonics is the process as to how Pangea formed.
- Plates move on top of the Earth's mantle, which is hot molten rock beneath the earth's crust.
- About 300 million years ago, all the continents were in the Southern Hemisphere moving closer together
- Over millions of years, they collided and formed the supercontinent Pangea.
- There were huge mountain ranges like the Appalachian Mountains, Ural Mountains, vast deserts such as the Sahara Desert, and huge Inland Seas such as the Permian Sea.
- Pangea started to break apart roughly about 200 million years ago
- Pangea split into Laurasia in the north, and Gondwana in the south.
- Over millions of years larasia and gondwana broke apart forming the continents of today.
- North America, Europe and all of Asia except for India were once part of Laurea.
- South America, Africa, Australia, Antarctica and India were part of gondwana.
- Rock and fossil studies in different parts of the world indicates what the Earth looked like millions of years ago
- Similar rock formations and fossils in places that suggests that these places were once part of the same land mass.
- The same dinosaur fossils in Africa and South America prove that they were once connected as a part of Pangea.
- DNA evidence further links humans from different continents to each other.
