How do air masses interact to form a tornado? O A. Cold, dense air flows toward the warmer, less dense air, so the cold front ends up moving faster than the warm front. O B. A cyclone rotates faster and faster as pressure differences between areas of low and high pressure increase. O C. A cyclone becomes slower and slower as pressure differences between areas of low and high pressure decrease. O D. Two air masses meet, but neither moves into the other one and spiral wind results.
