Slide 12:
Why are the inner planets made up of metallic elements and the outer planets
are gaseous?
Inner planets are hotter and closer to the Sun (origin) and outer planets are
cooler and farther away
Slide 15:
Why might Jupiter and Saturn be made up of H and He and the other gas
giants are made up of additional gases?
Jupiter and Saturn used up more of the H and He
Slide 16:
Where are two places that comets come from? Oort cloud, Kuiper belt
Slide 17:
How long does it take for a short-period comet to revolve around the Sun?
Less than 200 years
What direction do short-period comets orbit the Sun?
CCW
Where do short-period comets originate?
Kuiper belt
Slide 18:
How long does it take for a long-period comet to revolve around the Sun?
More than 200 years
What direction do long-period comets orbit the Sun?
Orbital path is random
Where do long-period comets originate?
Oort cloud
Slide 22:
Why are the smaller protoplanets unable to accrete gas?
Too hot
Slide 24:
What is the name of Pluto’s moon?
Charon
What temp does the surface of Pluto reach?
-400 C
Slide 25:
Why do some planets have metal cores?
Accretion + impact = heat, material starts to melt, metal is dense so it sinks to
the core
What are the crusts made out of?
Oceanic = basalt
Continental = granite
Slides 26 – 30
Write down the densities of Mercury, Venus, Earth, Mars, and Pluto
Mercury = 5430 g/m3; Venus=5240 g/m3; Earth = 5520 g/m3; Mars = 3930
g/m3; Pluto = 2060 g/m3
