The basic difference between volatiles and refractory
elements/compounds - ✔ ✔ volatiles condense into
solids (ice) at low temperatures. refractories condense into
solids (rocks and metals) at high temperatures
Whether all planets, moons, and asteroids experience
differentiation - ✔ ✔ it will occur in any celestial body
big enough (greater than 30 km in diameter) to generate
enough heat to melt its interior
Whether there is actually cold, solid ice within ice giants -
✔ ✔ water, ammonia, and methane are not in a
frozen solid state. The high pressures create hot slushy
mixtures, still referred to as icy
Which celestial bodies in general do not follow Kepler's
laws - ✔ ✔ Neptune and Uranus
Which planet was discovered based on its influences of
another planet's orbit - ✔ ✔ Neptune was found by
Uranus' orbit
, Why the gas giants had to form within 3-10 million years
from the birth of the Sun - ✔ ✔ they had to attract
hydrogen and helium gases before these were blown
away by the solar wind
Why the giant planets have faster spin rates than
terrestrial planets - ✔ ✔ because they are more
massive
Why the interiors of large asteroids and planets are very
hot inside - ✔ ✔ when they get big enough they heat
up inside due to the heat of accretion and radioactive
decay, causing the interior to melt
Why the spin axis of most planets is tilted relative to the
ecliptic plane - ✔ ✔ because of violent collisions with
large objects
The basic properties of an elliptical orbit - ✔ ✔ major
and minor axis, with two focus, and eccentricity is how
much change from a circle an ellipse is
