Continental drift is a highly supported scientific theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics , which studies the movement of the continents as ...
The granite outcrops of the Seychelles Islands in the central Indian Ocean were amongst the earliest examples cited by Alfred Wegener as evidence for his continental drift theory. [1] Ridge–plume interactions have been responsible for separating a thinned continental sliver from a large continent (i.e. India).
Wegener was involved in several expeditions to Greenland to study polar air circulation before the existence of the jet stream was accepted. Expedition participants made many meteorological observations and were the first to overwinter on the inland Greenland ice sheet and the first to bore ice cores on a moving Arctic glacier.
Wegener's continental drift hypotheses is a logical consequence of: the theory of thrusting (alpine geology), the isostasy, the continents forms resulting from the supercontinent Gondwana break up, the past and present-day life forms on both sides of the Gondwana continent margins, and the Permo-Carboniferous moraine deposits in South Gondwana.

The theory of continental drift provided an alternate explanation that did not require land bridges. [4] However the continental drift theory was not widely accepted until the development of plate tectonics in the early 1960s, which more completely explained the motion of continents over geological time. [5] [6]
He was an early proponent of Alfred Wegener's theory of continental drift, viewing plate tectonics and continental collisions as the best explanation for the formation of the Alps. He is also noted for his application of the theory of tectonics to the continent of Asia. He founded the Geological Institute of Neuchâtel, Switzerland.
