What are the main causes of tornadoes?
Tornadoes develop from severe thunderstorms in warm, moist, unstable air along and ahead of cold fronts. Such thunderstorms also may generate large hail and damaging winds. When intense springtime storm systems produce large, persistent areas that support tornado development, major outbreaks can occur.
Why do tornadoes spin?
Winds moving in different speeds and directions at different altitudes cause the rising air to start spinning. Air that spins as it rises is typical in supercells, the strongest type of thunderstorm, but not all spinning air creates a tornado. For a tornado to form, there also needs to be spinning air near the ground.
What is a tornado made of?
A tornado is a rapidly rotating column of air extending from a thunderstorm to the surface of the Earth. This mobile, funnel-shaped cloud typically advances beneath a large storm system. Tornadoes are visible because, nearly all the time they ave a condensation funnel made up of water droplets, dust, dirt, and debris.
Why are tornadoes formed in Class 7?
Answer: Tornadoes are formed when a funnel-like column of cold air sinks down from a storm cloud. Warm air from the earth’s surface rises up, whirls around and causes high speed winds.
