What is the “fuel” that “feeds” a hurricane
A
cold air
B
dry air
C
warm and moist air
D
warm and dry air
Explanation: 

Detailed explanation-1: -When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.

Detailed explanation-2: -Hurricanes are powered by the latent heat energy released from condensation. To form and develop they must be supplied with a constant supply of warm humid air for this process. Surface air with enough energy to generate a hurricane only exists over oceans with a temperature greater than 26.5°C.

Detailed explanation-3: -Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards.

Detailed explanation-4: -Once an air parcel reaches the hurricane’s eyewall, it turns upward and rises due to a process called convection. The added heat from the ocean causes the air rising in the eyewall to be warmer than the surrounding environment, allowing it to continue to rise.

Detailed explanation-5: -Warmer oceans fuel storms Evaporation intensifies as temperatures rise, and so does the transfer of heat from the oceans to the air. As the storms travel across warm oceans, they pull in more water vapor and heat. That means stronger wind, heavier rainfall and more flooding when the storms hit land.
