The action of continents drifting apart from each other is called, "Continental Drift". It is no longer a theory, as it has been proven to be so. Of course, as certain continents move apart from each other, they also are moving closer to other continents.
Continents are not tecnically moving 'away' from each other, they are just moving. This is due to the sub continent plates and the volcanic activity in the ocean. As new volcanic matter from the earths core comes to the surface it pushes continental plates apart.
plate tectonicts moved the continents awat from each other.
Plate Tectonics has some continents moving apart (e.g. North America and Europe) and others moving together or colliding (e.g. India and Asia). The movement is complex as it is driven by convection cells in the mantle.

Laurasia was a supercontinent that existed during the Paleozoic and Mesozoic eras. It was formed from the breakup of the supercontinent Pangaea. Laurasia eventually split into several smaller continents, which include North America, Europe, and Asia.
The San Andreas Fault in California is a well-known location in the U.S. where evidence of continental movement can be observed. Along this fault line, the Pacific Plate is moving northwestward in relation to the North American Plate, causing earthquakes and other geological phenomena.
Wegeners theory was that the tectonic plates in the earth were moving and colliding with each other due to temperature changes and convection currents at the core of the earth. Due to these plates moving, he thought that continents were drifting apart from each other, he then looked at a map of the earth and concluded that certain continents such as Africa and South America looked as if they had been joined previously as they seemed to fit together like peices of a jigsaw puzzle.
The plate tectonic theory is the belief that the earth's surface moves gradually over time and is not fixed. The theory holds true to the evidence of earthquakes which are the result of plates moving in opposite directions against each other.
Plate tectonics (This is the mechanism), the theory is continental drift.
Pangaea formed approximately 300 million years ago when all the Earth's landmasses were joined together as a single supercontinent. The movement of tectonic plates caused the continents to drift apart over millions of years, eventually resulting in the current layout of continents.
