Question

how does air density affect air pressure in a cyclonic storm (hurricane)?
a. warm air rises, creating an area of low pressure under it.
b. cool air rises, creating an area of low pressure under it.
c. warm air rises, creating an area of high pressure under it.
d. cool air rises, creating an area of high pressure under it.

Explanation:

Cyclonic storms like hurricanes form around low-pressure systems. Warm air has lower density than cool air, so it rises upward. As warm air rises, it leaves behind a region with less air mass near the surface, which creates an area of low pressure below it. Cool air is denser and sinks, which would create high pressure, so options involving cool air rising are incorrect, and options claiming warm air creates high pressure are also wrong.

Answer:

A. Warm air rises, creating an area of low pressure under it.
