Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why does cold water or land cause a hurricane to weaken?
A
because the high pressure of the hurricane can’t handle the cold water from a low pressure system
B
because the land always cools faster than the ocean
C
because the land breeze shreds the hurricane
D
because they cut off the energy supply to the hurricane
Explanation: 

Detailed explanation-1: -If the sea surface is too cool, there will not be enough heat available, and the evaporation rates will be too low to provide the tropical cyclone enough fuel.

Detailed explanation-2: -Hurricanes usually weaken when they hit land, because they are no longer being fed by the energy from the warm ocean waters. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they die out completely.

Detailed explanation-3: -Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart. Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms.

Detailed explanation-4: -When a tropical cyclone passes over land or cold water, the basic fuel that drives the storm is cut off–warm ocean water–is cut off. Passing over land will quickly weaken the storm (not because of friction as some believe, but because of the loss of the warm moisture source).

Detailed explanation-5: -Hurricanes spin counterclockwise (like all low pressure centers in the northern hemisphere) because of the Coriolis Effect. Because the equator rotates faster than other areas of the Earth’s surface, anything moving in a straight line on a North to South axis will eventually curve.
