with 100% Correct Answers
Which of the following general statements about Earth's atmosphere is not true? - A)
Earth's atmosphere blocks most UV light from reaching the surface.
B) Atmospheric scattering of light explains why our daytime sky is bright and blue.
C) Atmospheric pressure decreases with altitude.
D) The sea level temperature depends primarily on the total amount of gas in our
atmosphere.
E) Even in low-Earth orbit, where some man-made satellites are, some atmospheric gas
is still present.
D
All the statements below are true. Which one gives the primary reason why the surface
of Venus today is some 450 Celcius hotter than the surface of Earth? - A) Venus has a
much higher reflectivity than Earth.
B) Venus has a much stronger greenhouse effect than Earth.
C) Venus is only about 73% as far from the Sun as Earth.
D) Venus has a higher atmospheric pressure than Earth.
B
Which of the following statements about Earth's troposphere is NOT generally true? - A)
It is a layer of the atmosphere in which temperature declines with increasing altitude.
B) It is the lowest layer of the atmosphere.
C) It is the layer we live in.
D) It is the layer of the atmosphere in which ozone absorbs dangerous ultraviolet light
from the Sun.
E) It is the layer of the atmosphere in which convection plays the most important role.
D
In very general terms, how do the temperature structures of the atmospheres of Venus
and Mars differ from that of Earth? - A) They lack X-ray absorbing thermospheres.
B) They don't have an exosphere.
C) They lack ultraviolet-absorbing stratospheres.
D) Their atmospheres are similar in structure to Earth's, but with much higher
temperatures.
E) Temperatures in their tropospheres increase with altitude, rather than decreasing
with altitude.
, C
Does Venus have auroras around its poles, like Earth? Why or why not? - A) No,
because the high altitude clouds block the charged particles.
B) Yes, because it is bombarded by charged particles from the Sun.
C) No, because it lacks a global magnetic field.
D) Yes, because strong winds generate light near its poles.
E) No, because its atmosphere is too thick.
C
Which of the following is not caused by the Coriolis effect on Earth? - A) Hurricanes
swirl in opposite directions in the northern and southern hemispheres.
B) Air or objects moving northward in the northern hemisphere are deflected to the east.
C) Earth's global circulation cells are split into three separate cells in each hemisphere.
D) Water going down a drain swirls in opposite directions in the northern and southern
hemispheres.
E) Long-range projectiles deviate from their straight line course.
D
Why is the Coriolis effect so weak on Venus? - A) Because Venus has such a thick
atmosphere.
B) Because Venus rotates so slowly.
C) Because the clouds are too thick for this effect to show.
D) Because Venus is so hot.
E) Because Venus has such a strong greenhouse effect.
B
Why is thermal escape of atmospheric gas much easier from the Moon than from
Earth? - A) Because the Moon's gravity is so much weaker than Earth's, therefore the
escape velocity is smaller.
B) Outgassing on the Moon releases gases with lower masses than does outgassing on
Earth.
C) Because the Moon sometimes gets much closer to the Sun.
D) Because the Moon's average surface temperature is lower than Earth's.
E) Because the Moon lacks a global magnetic field, while Earth has one.
A
Observations indicate that the Moon has water ice in craters near the poles. Where do
scientists suspect this water came from? - A) Ice supplied to the Moon by impacts that
occurred within the past century or so.
B) The ice formed from the condensation of water released by outgassing on the Moon.
C) Ice brought by comet impacts long ago.
