The largest one is the Great Divide which goes goes from Alaska down the Rocky Mountains through North America, Central America and along the Andes Mountains to the tip of South America. Africa has many drainage systems including the Great Rift Valley, The Nile Congo Watershed, Zambezi River, and Limpopo systems. Asia has many drainage systems including the Central Asian Internal Drainage System, the Volga Caspian Sea System, and the Sistan Basin of Aran and Afghanistan. Australia has several including the Murray Darling System, the Brisbane system, Northern Australia system.
yes. every single other continent except antartica has continental divide.

The hypothesis that continents have moved is called continental drift.
Continental Drift
Continental drift is the idea that Wegener created, that all the continents were once a single landmass which he called Pangaea, and they have since drifted apart.
The moving of Continents.
The boundaries between continents are primarily defined by tectonic plate boundaries and oceanic features such as seas and oceans. These physical features create natural divisions that separate one continent from another.
Continental drift is the movement of the Earth's continents relative to each other.
continents
The Continental Slope. It's more correct to compare it to the coasts, for the Continental Shelf and Slope are part of the continents - they are simply submerged by present sea-level. In other words, the Continental Slope outlines are the outlines of the 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.
Continental drift.
Continental drift
The continental crust is the basis of the continents. It is the layer of rock, which is mostly granitic, that forms the continents and continental shelves.

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.
