FAQ
Frequently Asked Questions
Alfred Wegener, a German meteorologist and geophysicist, formally proposed the theory in 1912.
The observation of continental movement is accepted, but it is now understood as a consequence of the broader theory of plate tectonics, which provides the mechanism (seafloor spreading, convection currents) that Wegener lacked.
The main objection was that Wegener could not propose a convincing mechanism for how continents could move through the solid oceanic crust.
Pangaea is the name Wegener gave to the supercontinent that he proposed existed about 300 million years ago, which later broke apart due to continental drift.
The gradual movement of the continents across the earth's surface through geological time.
