continental drift

imenica

The gradual movement and formation of continents (as described by plate tectonics).
In geology, the theory that, about 250–200 million years ago, the Earth consisted of a single large continent (Pangaea), which subsequently broke apart to form the continents known today. The theory was proposed 1912 by German meteorologist Alfred Wegener, but such vast continental movements could not be satisfactorily explained until the study of plate tectonics in the 1960s.
The term “continental drift” is not strictly correct, since land masses do not drift through the oceans. The continents form part of a plate, and the amount of crust created at divergent plate margins must equal the amount of crust destroyed at subduction zones.
