Continental drift theory was proposed before the discovery of the mid-oceanic ridge, when it was hypothesized that the continents were actually plowing through the oceans. This theory was an attempt to explain the commonality of fossils on opposite sides of the Atlantic Ocean, and the observation on maps of the Earth that the North American and South American continents appeared to have been pulled apart from Europe and Africa. With the discovery of the mid-oceanic ridge, where new crustal plate is being created, and subduction zones, where plates are being destroyed, plate tectonic theory was born; that the crust of the earth is divided into many segments that are in constant motion, that the oceanic crust is constantly being recycled--all driven by heat from the Earth's interior. Plate tectonics is now nearly universally accepted as scientific fact, yet questions remain to be answered on some of the mechanisms of the process.

The main theory on the continental divide is that they relate to the plate techonics theory of the Earth's crust. The other theory is the continental drift theory where lighter rocks float on heavier crustal material.

Pangea separated by the theory of plate techtonics and continental drift. <3
no because continental drift means the hypothesis that the continents slowly move across earth's surface and plate techtonics means the theory that peices of earth's lithosphere are in constant motion.
When the Continental Drift Theory applies; when two plates either collide, smash, or slide to move plate techtonics.

The continental drift theory was replaced by the theory of plate tectonics.
continental drift is caused by plate tectonics
I think that continetal drift replaced his theory
Continental drift

Yes. The theory of plate tectonics is very broad, and it covers seafloor spreading, continental drift, plate boundaries and so on.
Continental drift is the theory that the Earth's continents have moved over time due to the movement of tectonic plates. Plate tectonics is the scientific theory that describes the large-scale movements and interactions of Earth's lithosphere. Continental drift was one of the key pieces of evidence that led to the development of the theory of plate tectonics.
