Tornadoes by Briana Johnson,[object Object]

What Tornados Come From,[object Object],Tornados mostly start from great storm clouds called super cells. If the super cells get strong enough , they eventually turn into a tornado.,[object Object]

Types of Tornados,[object Object],Waterspout- weak tornado formed over water ,[object Object],Land Spout- equivalent to waterspout but formed over land,[object Object],Multiple Vortex Tornado- a tornado that has more than one vortex, or a tornado with more than one spinning mass of cloud,[object Object],Satellite Tornado- small and weak tornado that forms near a stronger tornado; doesn’t cause much damage to surroundings,[object Object]

How Tornados Are Formed,[object Object],A wall cloud, the type of cloud that often results in a tornado, is formed when warm air and cold air meet going in different directions and speeds. It starts a tornado usually when it reaches about 35 mph. The air pressure can range between 975 and 1000, and the precipitation and temperature can be anything.,[object Object]

Where Tornados Mostly Appear,[object Object],Tornados form in most places with hot, moist air. The place where tornados mostly happen is in Tornado Alley or the Great Plains. In that particular area, there are over 500 tornados each year. Think about that compared to everywhere else in America!,[object Object]

Just Plain Creepy!!!,[object Object]

Special Info,[object Object],Where they most often occur- Tornado Alley or the Great Plains,[object Object],Types of precipitation- any kind ,[object Object],Interesting types of tornados- waterspout, land spout, multi vortex, and suction vortexes, satellite tornado,[object Object],Average wind speed- can range from speeds of 40 mph to 110 mph,[object Object]

What Tornadoes Can Do,[object Object],Tornadoes can move in speeds that range from 20-60 mph,[object Object],Can make a strong updraft that can destroy or lift things of the ground in a matter of seconds,[object Object],Can last for a few seconds, all the way to more than an hour,[object Object],People can lose homes, family, and everything they own in the short but devastating time of a tornado,[object Object]
