Final answer:
Hurricanes mainly occur in warm subtropical regions due to warm ocean water and the rotation of the earth.
Step-by-step explanation:
Hurricanes mainly occur in warm subtropical regions because they develop over water that is warmer than 80 °F. The warm air over the ocean heats up and rises rapidly, creating strong wind currents and storm conditions. As the air rises, it cools and condenses, resulting in heavy rains and a downdraft of cooler air. The rotation of the earth causes the storm to rotate in a cyclonic pattern, with hurricanes rotating counter clockwise in the northern hemisphere and clockwise in the southern hemisphere.
