I. The sun heats up the surface of the land. As the warm, less heavy air begins to rise, it meets the colder, heavier air above
it. II. With more warm air rising, the spinning air encounters more updraft. The winds spin faster, vertically upwards, and gains more momentum. III. The spinning winds creates a vortex and the wind has enough energy to fuel itself. IV. The faster moving air begins to spin and roll over the slower wind. As it rolls on, it gathers speed and grows in size. V. The tornado is moving in the direction of the thunderstorm winds. Touch down occurs. Consider the steps in tornado formation. Place the steps in correct order. Remember, the conditions needed to start the tornado forming process!
