I gave my students this multiple choice question: Thunderstorms and hurricanes are examples of severe weather. Which of these weather conditions is necessary for the formation of thunderstorms and hurricanes?

Only one answer is correct among these 4 choices:
- a cold rain falling to the ground
- air masses combining to create a high-pressure area
- winds spiraling downward and away from the center of a storm
- air moving toward the center of a storm and rising into the atmosphere

Could you tell me which one is correct?

air moving toward the center of a storm and rising into the atmosphere
