Mountain ranges linking in England and America
this is easy! I LEARNED IT IN SCIENCE! WERGNER DICOVERED IT. WEGNERS EARLIER THEORY OF CONTINENTAL DRIFT WAS REEXAMMINED AND A NEW THEORY WAS BORN ............................ THE THEORY OF PLATE TECTONICS
Tectonic plates, what the ground is on. they are always moving. Pangia, when the continents were together then "drifted" apart as time went by. Earth Quakes.... we would not have them if Tectonic plates didnt run into each other. Hence... the ground is always moving... slowly.. but surely..
New crust forms at mid-ocean ridges.
Plate tectonics is the idea that the Earth is made up of plates which move. Therefore the continents drift ever so slightly. The Earth was once made up of one big continent called pangea.

Wegener's idea of continental drift suggested thatcontinents moved, but it did not explain many otherparts of Earth's crust. Today scientists use the theoryof plate tectonics to explain why Earth's features appearas they do.According to the theory of plate tectonics, Earth's lithosphere is broken into about 20 moving plates. The continents and the ocean floor make up the surfaces of these moving plates.

Continental Drift. All of the land masses appear to be able to fit into one large land mass known as Pangaea.

plate tectonics theory
The existance of land bridges between continents
Tectonics.
The idea of continental drift has been subsumed by the theory of plate tectonics.
