The forces explaining the cause of continental drift have not been really elucidated. It is likely that convection forces do contribute to the movement of magma and continents. But complex theories have been developed to explain surface markings on the ocean floor.

The theory of plate tectonics indicates that the rigid plates slide over a partially molten, weak asthenosphere with the continents drifting passively along. Continental drift is therefore a consequence of the movement of the plates.

At some stage in history a process called continental drift began. We do not know when because the rocks have been squashed and changed so much since then, but it is important because it is still happening today. ... Some people think that it is one cause of ice ages.

All About Plate Tectonics: Earth's Plates and Continental Drift; The Earth's rocky ... The theory of plate tectonics (meaning "plate structure") was developed in the 1960's. This theory explains the movement of the Earth's plates (which has since been documented scientifically) and also explains the cause of earthquakes,

Continents drift very slowly around the world, shifting their positions. During our lifetime, the shape of the Earth's landmasses cannot be seen to change. This is because continental drift occurs at about the same speed as the growth of our fingernails.

The hypothesis of continental drift was largely developed by the German Alfred L. Wegener, a lecturer in astronomy and meteorology, ... His ideas were not widely accepted as critics thought that the evidence were not strong enough, that the underlying cause of the drift was not explained and that the drift was impossible.

Continental drift theory has been replaced by the science of plate tectonics, an all inclusive explanation of the process of continent movements, crust creation, lithologies, subduction, the rock cycle, and so on. The engine behind plate te...
