Use these questions to test your understanding. If you get them wrong, you will be linked back to the relevant part of the notes.
Be sure you study them thoroughly (don't just get a quick fix for your mistake) so your overall understanding is improved.
1. The metallic hydrogen in Jupiter's interior contributes to

d. its strong magnetic field e. its colorful atmosphere
2. The thermal emission from several giant planets
a. is larger than would be predicted from the amount of sunlight absorbed by the planets
b. is smaller than would be predicted from the amount of sunlight absorbed by the planets
c. indicates that the blackbody law is in error
d. indicates that these planets are comprised largely of ice
e. is only indicative of their distances from the sun
3. The high level of motions and activity in Jupiter's atmosphere results from

b. Convection driven in part by the interior heat of the planet
c. Chemical reactions that change the atmospheric pressure
d. Gravitational effects from the inner Jovian moons
e. effects of the planet's strong magnetic field
4. The low level of oxygen in Jupiter's atmosphere suggests that:
a. oxygen was not abundant in the early, outer solar system
b. the oxygen is all locked up in clouds
