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