Drift Theory	Plate Tectonics
1. Continental drift theory by Wegener assumes all the present continents to have arisen by the breaking and then drifting of the components of the supercontinent Pangaea.	1. Plate tectonics assumes the whole lithosphere to be divided into different major and minor plates which are constantly moving.
2. Continental drift theory only considers horizontal movement.	2. Plate tectonics takes into account the subduction of plates also.
3. Continental drift theory relies on circumstantial evidence of Jig-Saw-fit, fossils deposits etc.	3. Plate tectonics is based on scientific analysis of processes inside the earth's surface.
4. Continental drift theory relies on the concept of plate tectonics to be validated.	4. Plate tectonics theory validates the drift theory and is not to be validated by the same.
