Continental drift is a theory given to explain the formation of various plates or slabs on the surface of the earth and the theory is evident in the form of Alfred Wegener as a geologist who through his research and discoveries and advanced knowledge gave the concept.
Plates on which the landmasses and various features are made is not static as it looks and is more dynamic and was more destructive in the past as the formation of the earth during the 4.6 billion years ago the continental landmass underwent transformations and breakthrough happened as the split and rejoined and again joined to form what is seen today.
These plates drifted in such ways that the landmasses formed various properties of the northern and southern hemispheres. Wegener gave evidence of Jigsaw fit puzzle, drifting of the climatic zones, spreading of the plants and animals located at the same continental borders.
Moving of the plates under the action of gravity and wind speeds.
