continents move about as plates of crust and upper mantle, on more mobile layer of asthenophere in the mantle. Movement driven by mantle convection and isostasy.
Bumps between continents = mountain chains
bump continental with oceanic = island arc vocanoes and subduction of oceanic plate
The continental drift was to help explain how the fossil of animals and plants were found on different continents. Alfred Wegener developed a theory in 1912 suggesting that the continents were once connected as a supercontinent.
The gradual movement of the continents across the earth's surface through geological time.
Continental drift is a theory that Alfred Wengener, a German scientist, came up with. It stated that the continents were once all together, a Pangaea, but spilt and move apart over time.
Continental Drift is the movement of earth's continents relative to each other. Hope this helped!
Continental drift is the uneven heating of Earth's mantle which causes the tectonic plates to move. Every year, these plates move about two and a half centimeters.
the Earth's surface is made up of large moving plates
The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.
No, only Continental Drift Theory.
The theory of continental drift did originate in the 1930s. Continental drift asserts that the continents were once a single landmass called Pangaea that drifted apart over time.
The main problem with Wegners theory of continental drift was that at the time he proposed it he had no real proof.
Alfred Wegner originally thought of the continental drift theory, but he wasn't believed when he presented it. After his death (of course) the theory was proved.

I think that continetal drift replaced his theory
The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.
The continental drift theory was replaced by the theory of plate tectonics.
the Continental Drift Theory is the slow movement of the Earths continents. A.K.A the continents drift
No, only Continental Drift Theory.
Alfred Wegener's theory was known as the theory of continental drift.
earthquakes and volcanoes Do you know how to explain the theory of the continental drift?
Alfred Wegener Proved The theory of Continental Drift.
Alfred Wegener is the proponent or author of the Continental Drift Theory. lorzcute2000@yahoo.com
Seafloor spreading helped prove the theory of continental drift. Pangea theory also helped.
