They aren't. A tornado is a vortex of air, not water. The funnel of a tornado is formed by water droplets, but these droplets only account for a small percentage of the tornado's composition.
These droplets form because tornadoes are a product of thunderstorms, meaning there is usually a fair supply of moist air.
There are no tornadoes that are made of water, but tornadoes do touch down on water fairly often. Tornadoes on water are called waterspouts.
Tornadoes on water are called waterspouts.
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.
Yes, tornadoes on water are called waterspouts.
Tornadoes and waterspouts are essentially spinning columns of wind. Water vapor condenses to form the visible funnel cloud, and dust and debris, or water spray in the case of a waterspout may be lifted into the vortex as well. But for the most part they are made of air.
No. Tornadoes occur naturally.
Yes. Tornadoes formed over water are called waterspouts.
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.
No. Tornadoes usually form on land, not water. Tornadoes on water are called waterspouts. Tornadoes are spawned by thunderstorms, which are fueled by warm, moist, unstable air. A cold body of water tends to stabilize the atmosphere, making thunderstorms and tornadoes less likely. A warm body of water has the opposite effect.
Tornadoes most often form on land, but they can form over water.
They can, but most tornadoes happen on land.
Neither slat water nor sugar water make tornadoes. Tornadoes are an atmospheric phenomenon. If you mean those cool little tornadoes in the 2-liter soda bottles, both CAN make them. They will be much harder than distilled water though.
