There is no such thing as an actual tornado underwater, as a tornado is, by definition, a vortex of air. However, a vortex underwater is called a whirlpool.
An underwater "tornado" would not be a tornado; it would be a whirlpool. There are different ways they can form. If water is draining from a, the draining water can gain rotation from any eddies in the water. If a current is flowing over a rock or other object a series of whirlpools can form on the downstream side and get carried away by the current, or one may remain stationary by the object. Finally, water currents that come together in just the right way, such as when tides intereact with some topography, can create whirlpools.
They can, but they do not need to. Tornadoes formed by meachanisms within a thunderstorm and are not dependent when whther the storm is over or near water. The state with the highest number of tornadoes per area unit is Kansas, which does not have any bodies of water more significant than some rivers and small lakes.
Tornadoes are sometimes divided into "weak" tornadoes "strong" and "violent" tornadoes. Weak tornadoes are those rated EF0 and EF1. Most tornadoes are weak. Strong tornadoes are those rated EF2 and EF3. Violent tornadoes are those rated EF4 and EF5. They are the rarest of tornadoes, only about 1% of tornadoes are this strong.
Tornadoes are often referred to simply as "tornadoes" or "twisters."
The plural of tornado is tornadoes.

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.

No. A tornado that moves onto water will keep going without being significantly affected. In such a case it is called a waterspout. Waterspouts can also develop on water and then move onto land as tornadoes. There are numerous examples of tornadoes crossing water. Most notably, the three deadliest tornadoes in U.S. history all crossed the Mississippi River. See the links below for tornadoes moving across water.
It is not officially the reason behind it, it is one of the natural (not supernatural) options. It is commonly used with other natural processes like tornadoes and storms.

It would be sheer coincidence if they did. A tornado is primarily a land storm. There can be a tornado over the surface of water (called a waterspout), but either way, tornadoes have nothing to do with tsunamis, which are caused by undersea quake movements.
Tornadoes in the U.S. are called tornadoes.

Underwater landslides, Underwater volcanic eruptions, and Underwater earthquakes
It depends on what you mean by extreme. Tornadoes of EF4 and EF5 tornadoes, however are often referred to as violent tornadoes. These account for about 1% of all tornadoes.
