CBSE Class 11 Geography Chapter 4 Distribution of Oceans and Continents Notes
Alfred Wegener, a German meteorologist put forth “the Continental Drift Theory” in 1912. About 300 years ago, all the continents formed a single continental mass. The super continent was named ‘Pangaea’, which meant ‘all earth’. A mega ocean surrounded ‘Pangaea’, which was called ‘Panthalassa’, meaning ‘all water’.
Pangaea began to break up into two large continental masses called Laurasia and Gondwanaland. Laurasia and Gondwanaland continued to break into land masses, which look similar to our modern-day continents.
