Since there is no true consensus on what a continental divide is, there is no real agreement on where the triple points are. However, the main Continental Divide described in this article is a far more distinctive geological feature than the others and its two main triple points are much more prominent.
The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus floats on top of it. Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth's surface is now underlain by continental crust.
