Most of the time it is man's fault. Often, people mine under rivers. sometimes, the weight of the water causes the roof of the mine to collapse. Other times it is nature's fault. Sometimes, large amounts of pebbles shift underwater making a hole like a drain. Man-made whirlpools tend to last hours and are more powerful. Nature's ones only last a few seconds and are pretty weak.
They can. There are several down river from Niagara Falls.
Whirlpools most often occur in the late summer and early fall when the water temperature is warmer and there is strong tidal or current activity.
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.
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.
Yes, they occur naturally and sometimes(if large enough) have a tendency to sink ships that enter the proximity.
Kinda-sorta. Whirlpools in general are rare, and the ship-eating kind sometimes seen in movies don't occur at all.
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.
No. Not at all, actually. A sinkhole occurs when water has eroded the ground (usually limestone or an evaporite based rock) underneath the surface and it caves in. Sometimes, they occur due to human use (excessive lowering of the water table, etc.) A whirlpool is a circulating portion of water, usually found in the ocean.
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
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.
AnswerIn most of Johto and Kanto in Pokemon Crystal, whirlpools naturally occur in the water. No one Pokemon is responsible for the general amount of whilpools in Pokemon Crystal, and they simply serve as game features which obstruct your path until you have enough experience to pass them.However, the whirlpools surrounding Whirl Island are most likely to be caused by Lugia, who resides deep within the Island. Lugia lives in the ocean and is rumoured to have the ability to create whirlpools even when it moves.
