EAPS 105 Exam III Study Guide – || || || || || || ||
Questions With Answers || || ||
What are the components of a primary atmosphere? -
|| || || || || || || || ||
CORRECT ANSWER(S)✔✔hydrogen and helium gas (the || || || || || ||
rocky planets lost theirs and replaced it with newer ones)
|| || || || || || || || ||
What are the factors that influence a planet's escape
|| || || || || || || || ||
velocity? - CORRECT ANSWER(S)✔✔The greater the mass || || || || || || ||
of the planet, the higher the velocity needed to escape its
|| || || || || || || || || ||
gravity. The greater the radius of the planet, the lower
|| || || || || || || || || || ||
the velocity needed to escape its gravity.
|| || || || || ||
What are the factors that influence the velocity of an
|| || || || || || || || || ||
atmospheric gas molecule? - CORRECT ANSWER(S)✔✔The || || || || ||
higher the temperature of a gas molecule, the faster it
|| || || || || || || || || || ||
moves. The lighter a gas molecule, the faster it moves. If
|| || || || || || || || || || ||
a gas molecule moves faster than the planet's escape
|| || || || || || || || ||
velocity, it can escape into space. || || || || ||
Which planets have retained their primary atmospheres? -
|| || || || || || ||
CORRECT ANSWER(S)✔✔Jupiter, Saturn, Uranus, Neptune
|| || || || ||
What are the major differences between the atmospheres
|| || || || || || ||
of Earth and Venus? - CORRECT
|| || || || || || ||
, ANSWER(S)✔✔Atmospheric pressure is 90 times greater || || || || || ||
than on Earth. CO2 traps so much heat from the Sun that
|| || || || || || || || || || || ||
Venus has the hottest surface of any planet, 465 degrees
|| || || || || || || || || ||
C. Has sulfuric acid clouds.
|| || || ||
What are the major differences between the atmospheres
|| || || || || || ||
of Venus and Mars? - CORRECT ANSWER(S)✔✔Venus'
|| || || || || || || ||
atmosphere is 15,000 times denser than Mars' (Earth's || || || || || || || ||
atmosphere is 166 times denser than Mars'). Despite the || || || || || || || || ||
relative percentage of CO2 on Mars, there is not much of
|| || || || || || || || || || ||
it and thus the heat from the Sun is not captured to warm
|| || || || || || || || || || || || ||
its surface.||
What does Mars' thin atmosphere imply about the force of
|| || || || || || || || ||
its winds? - CORRECT ANSWER(S)✔✔even high winds
|| || || || || || || ||
would not pick up objects bigger than grains of sand
|| || || || || || || || || ||
(winds are not very strong at all) || || || || || ||
What is the problem with the theory that Mars may have
|| || || || || || || || || || ||
lost its atmosphere due to the solar wind? - CORRECT
|| || || || || || || || || ||
ANSWER(S)✔✔if this planet had lost its atmosphere from || || || || || || || ||
solar wind stripping, then why has Venus not lost its
|| || || || || || || || || ||
atmosphere as it also does not have a magnetic field and || || || || || || || || || || ||
is even closer to the Sun
|| || || || ||
Why does the temperature of the stratosphere increase
|| || || || || || || ||
with altitude? - CORRECT ANSWER(S)✔✔Ozone absorbs
