Whirlpools typically occur where strong opposing currents come head on.
Technically black holes are a malestorm of space time yet they share no resemblance whatsoever with whirlpools which as caused by an obstruction in the current.
The plain answer is that they end when they run out of energy. So they simply stop then. But there are all kinds of whirlpools caused by all kinds of things. Which means there are all kinds of ways whirlpools can get and lose their energies. For example, there are whirlpools in your bathroom sink when you open the drain. They stop when the water is gone from the sink and so there is no longer a force of gravity acting on water to cause the whirlpools. There are whirlpools in the wake of a ship. They're called eddies, but they are still whirlpools. They stop when the ship stops because they were getting their energies from the ship's motion. Similarly there are whirlpools in running streams and rivers, they might stop if there is a change in flow or the river runs dry. So there you are. Whirlpools stop when they run out of energy.
Both tornadoes an whirlpools are different types of vortex. But besides that they are very different. For one thing, how tornadoes function and develop is more complex than it is for whirlpools.
Sometimes. Most whirlpools are not all that dangerous. They cannot pull down large ships but there are more stronger whirlpools that could pull small ships and humans down with ease. They are known as Maelstroms.
make giant whirlpools
In the dragons den, behind the final gym in kanto/johto, starting region. Thats all I think.
Technically, there is no such thing as an underwater tornado. By definition a tornado is a violently rotating column of air. A vortex underwater is called a whirlpool. Whirlpools are not like tornadoes, however. They are not nearly as violent and are usually harmless, though some stronger whirlpools can pose a threat to swimmers and small boats. Natural whirlpools can be observed in streams and at some tidal inlets.
yes and no. little whirlpools like the ones in a sink when you drain the water won't suck you down but big whirlpools also called maelstroms can suck you down. but big whirlpools can't sink a big ships like in some movies. if you want to know how a whirlpool is formed its formed when two different currents pass each other.

fear of whirlpools or getting dizzy
yes
