No. Tornadoes do not need bodies of water to form. The most prolific tornado producing region in the world is on the Great Plains of the U.S. which sit in the middle of a continent. There are a few small lakes and rivers there, but these have little to no effect on tornadoes.
Yes it is a tornado over the water. However it is easier for a tornado to form over water and is generally smaller and weaker. Waterspouts are generally not officially counted as tornadoes unless they hit land.
No. A tornado is defined as a violently rotating column of air. A tornado can form on a body of water, in which case it is called a waterspout. Some water can get pulled up into it, but it is still primarily a vortex of air. Whirlpools, vortices that form in water, can look like tornadoes, but are not the same thing.
They can form on either on water or on land, but it is more common for them to form on land. A tornado on water is called a waterspout.
Generally the air is moist as tornadoes require thunderstorms to form.
Yes. A tornado on water is called a waterspout.
A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water and is connected to a cumuliform cloud. In other words, a tornado on water.
Partially. A tornado warning means that a tornado is likely to form or already has formed.
Some tornadoes break up when hitting a large body of water but some keep on going making a water tornado and occasionally picking up fish which later fall down and makes it seem as though it was raining fish. Then it turns pink and rotates faster. These are very dangerous so stay underground. These pink tornado's can also pick itself up and land near-by, as if it was jumping.
Any form of oxidation using galvanic cells does not require water
Waterspout is the correct term. If a tornado forms on water by the same mechanisms that it would form on land (i.e. from the mesocyclone of a supercell) it is called a tornadic waterspout.
well i think a tornado can form anywhere
No. A tornado warning means that a tornado is likely to form or has already been spotted.
