<span>Which statement best describes the formation of a hurricane?
A.Air pressure differences over the ocean cause fast, spinning winds.
B.An updraft of warm, moist air builds a cumulonimbus cloud.
C.A downdraft of air meets spinning updrafts.
</span>
Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
<span>A.Air pressure differences over the ocean cause fast, spinning winds.

</span>
<span>How are hurricanes and thunderstorms similar?
A.Both cover an area as large as 650 km.
B.Both involve the formation of large cumulonimbus clouds.

<span>Which severe weather condition forms over warm, tropical areas?

A. tornado
B. hurricane
C. thunderstorm
</span>
Thunderstorms result from the rapid upward movement of warm, moist air. They can occur inside warm, moist air masses and at fronts. As the warm, moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of over 12.45 miles.

Hurricanes develop in warm, tropical regions where the water is at least 80 degrees Fahrenheit  The storms also require moist air and converging equatorial winds.

A tornado can form where winds blow at different speeds causing rotation which can tighten and speed into a funnel cloud if caught in the flow of air moving into the storm. Rain and hail can cause the funnel to bend downward.

<span>B. hurricane is your answer


Hope it helped :)
