salt and water wind and tides heat and moisture waves and flooding
I gave my students this multiple choice question: Hurricanes are large, powerful storms that form as they travel over warm ocean waters. What do oceans add to make hurricanes so strong?

Only one answer is correct among these 4 choices:
- salt and water
- wind and tides
- heat and moisture
- waves and flooding

Could you tell me which one is correct?

heat and moisture
