Tornadoes are made of air necause they are a weather phenomenon and occur within Earth's atmosphere, which is made of air.
Tornadoes do not produce gasses. They are made of air and do not change its composition.
Tornadoes themselves are made of violently moving air and form from interactions of various moving parcels of air in and around a thunderstorm.
A tornado is made of air. Air moves into a tornado and spirals upward at high speed.
Tornadoes are just rapidly moving columns of air. The reason that they are black is because that is the color of the dirt that they pick up.
No. Tornadoes can be very destructive, but they do not cause air pollution.
No. A tornado is essentially just made out of air with dust, debris, and condensation mixed in.
Tornadoes most often form where cool dry air and warm moist air collide. This does not directly produce tornadoes but rather produces the thunderstorms that, given a few other factors, can sometimes produce tornadoes. Additionally, such a meeting of air masses is not absolutely necessary for tornadoes to form.
Guam has been the site of tornadoes before. Tornadoes can form anywhere cold and warm air collide, causing an imbalance in air pressure.
Tornadoes form most often when warm moist air collides either cool air or dry air. This produces thunderstorms. Other conditions are needed for those storms to produce tornadoes.
Tornadoes do not come to life as they are not alive. As to, who, the answer would depend on your religious standpoint. Most scientists would say that nobody creates tornadoes; they are just a consequence of interactions of air currents in a thunderstorm. A Christian would likely say that God creates tornadoes.
Antarctica is too cold for tornadoes to form. Tornadoes need energy from warm air.
No. The common description of tornadoes forming from a collision of hot and cold air is a gross oversimplification. The collision of air masses often produces the storms that spawn tornadoes, but is not a direct cause of the tornadoes themselves. The storms do not necessarily arise from such a collision either. However, the presence of hot, humid air is one of the most favorable factors for tornadoes to form as that is when the air holds the most latent energy.
