Prepare a note on the Continental Drift Hypothesis. |
|
Answer» Alfred Wegener, a German meteorologist, put forward the idea of continental drift in 1912. He argued that millions of years ago, all the present-day continents were a single unit forming supercontinent named Pangea which was encircled by an ocean called Panthalassa. Wegener believed that over millions of years, the continental portions drifted over the ocean floor forming the present continents. Some recent studies indicate that mostly all the continents on earth come together once in every 500 million years. It is believed that the most recent formation of Pangea was about 200 million years back, which means that we will have to wait for another 300 years for the next Pangea |
