A tornado is a type of severe cyclone. Which statement best explains how a tornado might form?
O A. A cyclone becomes slower and slower as pressure differences
between areas of low and high pressure decrease.
B. Cold, dense air flows toward warmer, less dense air, so the cold
front ends up moving faster than the warm front.
O C. A cyclone rotates faster and faster as pressure differences
between areas of low and high pressure increase.
D. Two different air masses meet, but neither moves into the other
one, and a spiraling wind results.
