This particular vortex is caused by two different currents meeting, however there are many causes for whirpools in nature. It happens when a fast
moving current collides with a slow moving current (probably slow because of the gradient of the earth underneath it), which causes the fast moving
current to bend around the slow moving current. This then causes the slow moving current to go round and round because the faster current has more
energy, thus making it impossible for the slower moving current to "escape" the faster.
The water isn't going down some hole to the core or anything, it will simply be dispersed in all directions once it reaches the "bottom".
