Put the steps in the development of a tornado in the correct order, starting with the first.
Warm air rises and cold air falls while the direction of those air masses changes simultaneously.
Warm and cold air masses intersect at different altitudes at the base of a supercell thunderstorm.
Clouds generate an updraft, with the vacuum effect pulling both spiraling columns of air upward.
Two invisible columns of wind spiraling and moving horizontally across the earth are generated.
