3. what is a tornado????AND THE IMPACT!
A tornado is a funnel of wind. They are very strong storms. Tornadoes usually happen in tornado alley. The impact is usually really bad. It causes BAD damage. Hundreds of people die. It takes a long time to rebuild. Many people are left homeless. The impact on people is very sad because they may die, lose a family member, lose their home. People rush to towns to clean up the damage, help people, spread happiness.

4. HOW DO TORNADOES FORM?????????
They form when warm air, and cold air masses meet together. The wind spins the air into a funnel cloud. The tornado spins the air VERY fast as it moves along. Wind speeds can get up to 300 miles per hour!! There is a scale called the ENHANCED FUJITA SCALE !!!!!!!!!!!!
