NAS CHAPTER 10 TEST QUESTIONS AND ANSWERSIn equal volumes, which of the following air masses has the largest surface air
pressure? - The answer is A.
During the summer, at the same pressure, maritime tropical air is _____ continental
tropical air. - Answer: less dense than
ANSWER: The American Southwest is a source zone for continental tropical air.
Cold and humid air: - mP.
At the same pressure, which of the following air masses has the least density? -
ANSWER Maritime Tropical
Which of the following air masses is the most thick in winter, given the same
pressure? - ANSWER Arctic
A(n) ____________ air mass experiences the highest temperature variation
between winter and summer. - ANSWER The continental polar
Air mass modification is typically most rapid when continental polar air flows over
bare ground.

warmer than
A front is a narrow zone of transition between air masses that differ in - Any of
these is correct.
, As a warm front approaches, clouds appear in which of the following order? -

front's. - The answer is narrower than
A cloud linked with a fast-moving, well-defined cold front. - Answer
cumulonimbus.
Warm fronts frequently follow cold fronts. - ANSWER: slower than
The front generated when the leading edge of cold air meets with a warm front is
referred to as an occluded front.
An occluded front develops late in the life cycle of an extratropical cyclone.
The most common type of occlusion in the Great Lakes region is a cold-type
occlusion.
Surface air pressure decreases when horizontal divergence aloft coincides with
horizontal convergence at the surface. - The answer is greater than
In a developed extratropical cyclone, fog and drizzle are most likely to form in the
cold air just ahead of the surface warm front.
