Question

what forms the basis of Wegener's 'Continental Drift Theory'?​

Answer 1

Answer:

Alfred Wegener was in  1 November 1880 and died in November 1930 at the age of 50. He was a German polar researcher, meteorologist  and geophysicist.

Explanation:

Alfred Wegener came upon the idea of  the Continental Drift Theory by noticing that the different large landmasses of the Earth almost fit together like akin to a  jigsaw puzzle. The Continental shelf of the Americas fit well to Africa and Europe, and Antarctica, Australia, India and the island of Madagascar fit to the tip of Southern Africa.

Wegener publicly advocated the existence of continental drift from 1912 . He argued that all the continents were once joined together in one landmass that had since drifted apart. He thought the drift was due to  the centrifugal force of the Earth's rotation  or the astronomical precession

Answer 2

Answer:

Alfred Wegener’s hypothesis was that before separating apart and drifting into their present locations, continents must have formed single landmass known as a Pangaea.

Explanation:  

His perceptions towards Earth’s rotation were that, the rotation caused the continents move apart from each other as well as shiftment towards each other. But this perception was not true and geologists decry “Wegener’s Continental Drift Theory”, published in a book called “The Origin of the Continents and Oceans” in 1915.
