  3. What Is a Tornado • A Tornado is a natural disaster. The natural ingredients that help make up deadly twisters. • A tornado is a powerful storm, which is created when moist, warm air gets trapped beneath a stable layer of cold air.

  4. Tornado Damages • Twisters can cause thousands to millions of dollars in damage. • The Oklahoma City tornado on May 3, 1999, was one of the most expensive tornadoes in U.S history. • Once a tornado strikes, the severity can vary; the land that is destroyed is often hard to restore.

  5. How Tornadoes Are Made • Tornadoes are created when moist, warm air gets trapped beneath a stable layer of cold air. • Tornadoes are formed when a rotating column of air extends from the base of a thunderstorm cloud to the ground.

  6. How Tornadoes affect Air • The most fundamental thing you have to understand is that heavier gases weigh more than lighter gases. • Different chemical elements, as you know, have different atomic weights. • Those which form gases (like nitrogen, oxygen, etc.) often combine two atoms at a time to form a gaseous molecule - like N2 (two nitrogen atoms) or O2 (two oxygen atoms).

  7. Where Do Tornadoes Occur • Tornadoes have hit all fifty states, but this does not occur often. • Most tornadoes occur in what is know to many of us as “Tornado Alley”. • Many of those states within the alley thrive on those weather conditions during spring and summer.
