A whirlpool is a small "underwater" tornado. It is created by two currents or tides coming from different directions and colliding.
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.
Whirlpools typically occur in ocean currents where opposing currents meet or in areas with strong tidal flows such as straits and narrow channels. They can also form around natural underwater obstructions or rapidly changing water depths like in rivers or near waterfalls.
Some famous natural whirlpools include Saltstraumen in Norway, the Corryvreckan in Scotland, and the Naruto whirlpools in Japan. These whirlpools are known for their powerful currents and swirling waters, which attract visitors and researchers interested in their natural phenomena.
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.
The pull of gravity needs a shallower depth to produce the Whirlpool.

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.

Whirlpools are dangerous because they can trap and pull swimmers underwater, causing them to struggle to reach the surface. The strong circular currents created by whirlpools can be difficult to escape from, especially for weaker swimmers or those caught off guard. Additionally, whirlpools can quickly carry a person away from safety or to deeper waters, increasing the risk of drowning.
Whirlpools are formed in nature when there is a current or eddy in the water flow as the speed of the water itself is slowed considerably by the resistance of the bed and banks. If there is a change of direction and also a drop then a whirlpool can form.
