EAPS 105|61 Exam III Study Guide
Is there debate within the scientific community about the current causes of global
warming? - ✔ ✔ Climate models lead to the unequivocal conclusion that
human emissions of greenhouse gases are responsible for the current rise in
global temperatures; There is no debate about this in the scientific community
Why does the temperature of the troposphere decrease with altitude? - ✔ ✔
This layer of the atmosphere is heated from the ground, causing it to be
warmest near the surface. As warm air rises, it expands because of less pressure
with altitude causing it to cool (same energy in a lager volume)
Why is Haley's comet the most famous of all comets? - ✔ ✔ Because it is a
short-period comet that comes into view about once in a lifetime (75 years), only
short-period comet that is visible to the naked eye
Why is Mars the most explored planet? - ✔ ✔ It holds the greatest chance of
finding evidence of past or present extraterrestrial life
Why might it be raining diamonds within the interiors of Uranus and Neptune? -
✔ ✔ There is a lot of methane in their atmospheres and icy mantles. High
pressures can strip the hydrogens from methane molecules leading to free
carbon, which then might compress into diamonds and rain down onto the planet
core.
Is there ice on Mercury? - ✔ ✔ Ice can be found within craters near the north
pole that are always in shadow
What are asteroids primarily comprised of? - ✔ ✔ Rock and relatively little ice
What are Kuiper Belt objects primarily comprised of? - ✔ ✔ Objects here were
formed beyond the ice line and are thus composed of rock and ice
What are Milankovitch Cycles? - ✔ ✔ Past global temperature changes being
mostly due to changes in Earth orbital parameters; Large changes in temperature
, have occurred throughout history. Several times in the past hundreds of
thousands of years we have been warmer.
What are seasons like on Uranus? - ✔ ✔ Extreme seasons are experienced
here - all or no sun for 21-year-long summers and winters, transitioning into 17
hour days for 21-year-long falls and springs
What are the basic differences between Jupiter's belts and zones? - ✔ ✔ Belt:
low, warm clouds; cool material sinks and warms (darker in color, orange)
Zone: high, cool clouds; warm material rises and cools
What are the components of a primary atmosphere? - ✔ ✔ 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? - ✔ ✔ 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? -
✔ ✔ 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.
What are the important factors enabling life to evolve on Earth? - ✔ ✔ The
moon's gravitational pull stabilizes our planet's rotation, preventing drastic
movements of the poles that could cause massive changes in our climate. Earth's
magnetic field helps protect us from solar radiation and cosmic rays which are
extremely hazardous to life. CO2 levels must also be kept low in order for oxygen
breathing life to flourish which we have plate tectonics to thank for.
What are the major differences between the asteroid belt and the Kuiper belt? -
✔ ✔ This belt is 20 times wider and 100 times more massive than the asteroid
belt, with many more larger bodies.
