Question

which factors are necessary for a hurricane or typhoon to form?

a. the sun emits radiant energy.

b. warm air rises, while cold air rushes in.

c. tropical ocean waters increase in temperatures.

d. the air masses are of different temperatures.

e. the air is humid.

Explanation:

Hurricanes/typhoons form over warm tropical oceans (≥26.5°C) to fuel evaporation, need humid air for latent heat release, and involve rising warm air with cold air replacement. While solar energy is a base driver, it’s not a direct necessary factor; different air masses aren’t required.

Answer:

B. Warm air rises, while cold air rushes in, C. Tropical ocean waters increase in temperatures, E. The air is humid
