The "fire tornado" forms from the fire; it doesn't really matter how the fire starts. Also, a "fire tornado" is more properly called a fire whirl as it technically isn't a tornado.
No, lightning does not come up from the ground during a thunderstorm. Lightning typically originates from the clouds and strikes downward towards the ground.
Lightning can come from the ground as well as from the sky. It can occur when a discharge of electricity happens between a cloud and the ground, or between two clouds.
There are many types of lightning STREAMERS that start a lightning strike. There are 3 basic places where streamers will originate from. They can come from a cloud to the ground or the ground to a cloud or from cloud to cloud. So your teacher was correct. But not always from the ground.
It comes out once it makes its path to the ground.
Yes, lightning can come from the ground because the electrons want to go to the holes in the sky. Most people think that lightning comes from the clouds, but it doesn't. There is no electricity in clouds, only moisture.
Beyond the fact that they come from thunderstorms and can be dangerous, tornadoes and lightning have virtually nothing in common. Lightning is a massive discharge of static electricity that occurs during a thunderstorm due to the separation of electrical changes. As a result of instantaneously superheating the air, lightning produces as shock wave that is heard as thunder. When lightning strikes the ground it can start fires and electrocute people nearby. The whole bolt typically only lasts a fraction of a second. A tornado is a violently rotating vortex of air extending from the base of a thunderstorm to the ground. Air spirals into a tornado and then upwards, attaining very high speeds. These powerful winds are strong enough to damage or destroy objects they strike, and can pick up objects, turning them into deadly projectiles. In the worst cases tornadoes can level entire towns with their winds. Although most tornadoes last a few seconds to a few minutes, in rare cases a tornado may last several hours. By definition a thunderstorm must produce lightning, but only about 1% ever produce a tornado.
There has to be circulation inside of a storm which if there is a tornado then it has that circulation. What makes it touchdown is when you have a strong updraft and downdraft which pushes that horizontal rotation into a vertical position which causes the funnel cloud to come in contact with the ground causing a tornado.
the sky is part of our atmosphere which is in earth so it comes from earth
I am 100 percent sure that lightning comes from the clouds. The bottom part of the clouds are sometimes negatively charged and when they get near high objects (usually trees or tall buildings) they release all the negative charged atoms as plasma.
Yes, it is possible for there to be 3 tornadoes on the ground at the same time, though it is unusual for them to come close to one another.
No. Tornadoes come from thunderstorms, which form in the air. The tornado itself starts forming several thousand feet above the ground.
