Question

How do air masses interact to form a cyclone?

A. The Coriolis effect bends global convection cells into a funnel pattern.
B. Air moves in a spiraling pattern from centers of high pressure toward centers of low pressure.
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.

Answer 1

B. because areas of high pressure go into areas of lower pressure creating a cyclone 

Answer 2

Cyclone is formed when a large air mass rotate around a center of point with low pressure

As we know that cyclones are characterized by spiral shapes so the reason of formation of cyclones is spiral movement of air mass towards centers of low pressure from centres of high pressure

so the correct answer is

Air moves in a spiraling pattern from centers of high pressure toward centers of low pressure.
