CAP Mitchell Aerospace Test Questions And
Answers
1. A blanket of air made up of a mixture of gases that
surrounds the Earth and reaches almost 350 miles from the
surface is called the ______.
a) Biosphere
b) Lithosphere
c) Atmosphere
d) Stratosphere
Correct Answer: c) Atmosphere
Rationale: The atmosphere is the envelope of gases
surrounding Earth. The biosphere refers to life, and the
lithosphere refers to the Earth's crust .

2. Which layer of the atmosphere contains the ozone layer,
which absorbs harmful ultraviolet radiation?
a) Troposphere
b) Stratosphere
c) Mesosphere
d) Thermosphere
Correct Answer: b) Stratosphere
Rationale: The stratosphere extends from about 10 to 30 miles
and contains the ozone layer (ozonosphere) which filters UV
radiation. The troposphere is where weather occurs .
3. What is the standard sea level pressure in inches of
mercury (in Hg)?
a) 29.00 in Hg
b) 29.92 in Hg
c) 30.00 in Hg
d) 14.70 in Hg
,Page 3 of 165
Correct Answer: b) 29.92 in Hg
Rationale: Standard atmospheric pressure at sea level is 29.92
inches of mercury. 14.70 refers to pounds per square inch
(psi) .
4. Which layer of the atmosphere begins at about 25 miles
and extends to about 250 miles, where electrons are gained
or lost due to solar radiation?
a) Troposphere
b) Stratosphere
c) Ionosphere
d) Exosphere
Correct Answer: c) Ionosphere
Rationale: The ionosphere is characterized by ionization (loss
or gain of electrons) caused by the Sun's ultraviolet radiation
and cosmic rays .
5. The jet stream usually crosses the United States at
______, generally moving west to east.
, Page 4 of 165
a) 10,000-15,000 ft
b) 30,000-35,000 ft
c) 50,000-55,000 ft
d) 5,000-10,000 ft
Correct Answer: b) 30,000-35,000 ft
Rationale: The jet stream is a high-speed river of air located in
the upper troposphere/lower stratosphere, typically found at
30,000 to 35,000 feet .
6. A wind that is blowing from the southeast is called a
______ wind.
a) Northwesterly
b) Easterly
c) Southeasterly
d) Southwesterly
Correct Answer: c) Southeasterly
Rationale: Winds are named by the direction from which they
