- A tornado is a narrow, violently rotating column of air that extends from a thunderstorm to the ground.Tornadoes form when warm, humid air collides with cold, dry air
- They can cut through massive swaths of forest, destroying trees and wildlife habitat, and opening up opportunities for invasive species to gain ground
- Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere.Image result for what is a thunderstormThunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds
