The Evolution of Earth's Continents

C G13/1/20

Many people believe that Pangea was the first supercontinent of the earth.
According to geologists, continents have been constantly drifting since the formation of the earth. This idea of continental drift was proposed by the German geophysicist, Alfred Wegener.

Therefore, the Pangea was not the first supercontinent. Before it, there were ancient continents:

  • Vaalbara formed 3.6 to 2.8 billion years ago and is thought to be the very first continent.
  • Ur formed 3 billion years ago and is the oldest confirmed continent.
  • Columbia formed 2.5 billion years ago.
  • Rodina formed 1.9 billion years ago.
  • Pannotia formed 650 million years ago.
  • Gondwana formed 570 million years ago.
  • Laurasia formed 300 million years ago.
  • Pangea formed 250 million years ago.

It is from this last supercontinent that Africa, America, Europe and other continents emerged.
