the movement of the continent i :-)
Continents can drift apart from one another and have done so in the past.

Yes
It states that all the continents were once a single supercontinent and broke up and drifted to their current locations.
Wegener's hypothesis of continental drift proposed that continents were once joined together in a single landmass called Pangaea and have since drifted apart over time. This theory laid the foundation for the modern theory of plate tectonics, which explains the movement of Earth's lithosphere.
Most people actually state that Darwin beat Wegener to the theory of continental drift as he mentioned in most of his studies about the continents drifting apart and fitting together.
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
The only evidence that Alfred Wegener did not have was the mechanism that drove the Continental Drift, he had evidence to support that the continents were once joined together, but did not have the means to postulate how the continents had actually moved to their present positions. He did however postulate the theory of a "layered Earth" consisting of a rigid surface (continents) upon a liquid/plastic like substance (mantle) and that if pressure was exerted on the surface layer, it would move thus, and if the pressure was removed the surface would return to its original state. It was only until c. 1890, when the Geophysicist Arthur Holmes came up with the theory of convection currents in the mantle being responsible for Continental Drift.
The theory used to explain changes in state is the Kinetic Molecular Theory. This theory states that the state of matter is determined by the movement and energy of its particles, with changes in state occurring when the particles gain or lose energy.
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.
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. He argued that these land masses have drifted apart over time to their current positions.
