No. Tornadoes are purely wind events. The storms that spawn tornadoes, however, typically produce heavy rain. So, tornadoes can be accompanied by flooding, but the flooding is not a product of the tornado itself. Hurricanes, which some people confuse with tornadoes, can also cause major flooding.
No, hurricanes do produce floods but tornadoes do not, although the storms that produce them can.
It is possible, though the tornado itself would not be the cause. Tornadoes are often accompanied by very heavy rain which can cause flooding. A flood can alter the course of a river.
No. Tornadoes can be very destructive, but they do not cause air pollution.
No. Tornadoes do not cause flooding.
Based on U.S. statistics about 2% of tornadoes cause deaths which works out to about 25 killer tornadoes in an average year.
Nothing COSSES anything. There are things that CAUSE tornadoes.
We don't need tornadoes. They cause death and destruction.
Nothing. Tornadoes are a natural weather phenomena.
No. Since tornadoes form in thunderstorms they are usually accompanied by lightning, but they do not actually cause lightning.
There is no way for people to cause tornadoes.
No, tornadoes do not cause deposition. Tornadoes are mainly associated with erosion, as they can pick up and carry loose particles and debris within their strong winds. Deposition usually occurs when the wind slows down and drops these materials.
Humidity itself does not cause tornadoes. Tornadoes form from the interaction of different air masses with varying temperature, humidity, and wind conditions. High humidity levels can contribute to the instability needed for severe thunderstorms that can produce tornadoes under the right atmospheric conditions.
