How is a tornado formed?

  1. Rising warm air

  2. Rising cold air

  3. Falling warm air

  4. Falling cold air

The correct answer is: Rising warm air

Tornadoes are formed from warm air that rises rapidly and meets with cold air. This warm air rises because it is less dense than the colder air. Simply put, cold air tends to stay closer to the ground while warm air rises up to try and reach an equilibrium. Therefore, options B, C, and D are incorrect as they do not involve the rising (instead, falling) of warm air.
