Good ones to think about:
1. Review # 4, p. 144. The Earth's weather erodes our craters.
2. Review # 1, p. 226. The inner planets are rocky. They were formed at high temperatures, so H, He, and other "volatiles" were "cooked" off of them by the Sun's energy.
The Jovian planets are more gassy. They were formed at cold temperatures, far from the Sun, so gases & volatiles could condense onto the planetesimals, and wern't "baked out."
3. Review # 4, p. 324: a neutrino ain't a neutron!
masses differ, neutrons react by strong force, neutrinos hardly react at all
4. Thought # 10, p. 324.
big ones from little ones, a.k.a., FUSION: a., b., d., e.
little ones from big ones, a.k.a., FISSION: c.
5. Review #15, p., 325.
convection: convection oven, boiling liquids
radiation: microwaves, camp fire,
sunhine on my shoulder
Hand these in:
1. Review #3, p.144. Full credit for four each.
(4 pt.)
|
terrestrial planets closer to Sun most heat from Sun rocky warm smaller no rings few moons |
Jovian planets farther from Sun most get most heat from internal heat sources compsed primarily of gas and "volatiles" cold large rings many moons |
2. Review #6, p.182. (4 pt.)
3. Thought #8, p.205, first question only. (1 pt.) Venus is cloudy, so we can't see the surface in the visible range. Hence, it makes sense to use a different wavelength for imaging.
4. Review #8, p. 246. (3 pt.) -- credit given for first two, and plausible attempt at third
5. Review #5, p. 266. (2 pt.) The text outlines three chioces: orbit Sun until breakup, impact with a planet, or ejection from solar system
6. Problem #20, p. 284. (5 pt.)
7. Review #3, p. 306. (2 pt.) They're colder than the surrounding atmosphere.
8. Review #5, p. 306. (3 pt.) -- many choices! here're three, all conveniently listed in the chapter summary:
9. Review #2, p. 324. (4 pt.)
If the Sun was fueled by either method, it would've burned out too quickly.
10. Review #5, p.324. (2 pt.)
Any reasonable approximation of the following will get full credit: Hydrostatic equilibrium means that the Sun's outward gas pressure is balanced by the inward force of gravity, so the Sun is neither contracting or expanding, but is constant in size. ("hydro-" = fluid, like the Sun's gassy interior; "static" = constant; "equilibrium" = balance)
