The correct answer is Alfred Wegener.

The hypothesis of continental drift was given by Alfred Wegener in 1912  to explain the arrangement and origin of continents and ocean basins.

  • According to him, continents formed a single continental mass called ‘Pangaea’ which was surrounded by a mega ocean called ‘Panthalassa’.
  • In the Jurassic period (200 million years ago) Pangaea begins to split and broke into Laurasia and Gondwanaland.
  • Further Laurasia and Gondwanaland further continued to break into various smaller continents that exist today.
  • He gave the evidence of radiometric dating, matching of continents paleoclimatic evidence, etc.
