A whirlpool is a rotating body of water that occurs when two currents meet or one current hits a wall.
Whirlpools can emerge in various sizes depending on the amount of water and the intensity of the interacting waves.
The majority of these phenomena are usually not dangerous. However, certain whirlpools can be extremely strong and hazardous.
A maelstrom is described as a whirlpool that is especially "large, forceful, or violent."
Technically speaking, the correct phrase for a whirlpool with a downdraft is a vortex.
Tides frequently generate whirlpools in maritime straits with narrow channels and swiftly moving water.
Even though only small boats are in danger, there are stories of craft getting pulled into a "whirlpool."
Smaller whirlpools can be seen downstream of artificial structures like weirs, dams, and near river rapids. Large cascades, like Niagara Falls, can also create strong whirlpools.
