Answer:
A tornado is a violently rotating column of air.
Explanation:
Tornadoes are one of the most powerful type of weather. It generally form a funnel shape. Large tornadoes usually form during the time of thunderstorm. There have many conditions for the creation of tornadoes. A large thunderstorm occurs in a high cloud and changes occur in wind direction. The change in the wind direction and wind speed causes air to swirl horizontally. A funnel is formed and the funnel of swirling air begins to suck the warm air from the ground. Eventually the funnel become larger and touches the ground and becomes a tornado.
Warm moist air rises, causing upward vertical motion of air into the thunderstorm.
The air diverges, or spreads out, above the storm.
Cold air from about 20,000 feet sinks into the thunderstorm, giving the storm downward vertical motion
The cold air and the warm air collide in the thunderstorm, and this creates a vortex, or a spinning, in the thunderstorm
This spinning leads a sinking cloud to form what is called a wall cloud.
The spinning and sinking intensify, allowing the cloud to get closer to the ground. This is known as the funnel cloud.
Now the spinning and sinking leads to extreme downward motion. The cloud touches the ground, and when it does it is known as a tornado
