Review 2

1. Mercury, Venus, Earth, Mars
2.Jupiter, Saturn, Uranus, Neptune
3.Asteroid belt
4.What is the Kuiper belt is mostly unknown, rocky, icy, home to Pluto, Charon, Pluto's moon, and a multitude of Plutoids
5.Oort cloud makes up more than half of the solar systtem
6. Comets
7. in class, tweet me if you want to know
8. Rocky (terrestrial) planets
9.List the parts of a comet. Head, tail, coma
10.A rocky object in space
11.Forms from the melting of the solar wind
12.A meteor actually interacts with the earth's atmosphere. It's a semantic difference, which means they use a different word than asteroid to make it seem unique.
13.Gassy planets are mostly atmosphere, and all the rockies except for Mercury.Pluto is a maybe
14.Too much methane, carbon dioxide and water in an atmosphere can hold heat, and make the planet warm.Venus is an extreme example of that.
15.Mars
16.Explain seafloor spreading using a picture. See picture below
17. An optical illusion where a planet moves backwards in comparison with the background stars.
18.A hurricane that is 3 times the diameter of the Earth.
19.Pluto
20.Pluto, if you think it is a planet. Neptune, if you believe Pluto is not a planet
21.Which planet travels faster? Mercury, so it doesn't fall into the sun.
22.It convinced Galileo of geocentrism.
23.Because the planets are ellipses, not circles.
24.All REVOLVE CCW, Venus rotates CW on its axis.
25.Neptune
26.All the gas planets do.
27. Rock.
28.Find out at http://www.solarviews.com/eng/edu/weight.htm
29.Terrestrials and rockies are the same thing. They are denser than gas planets.
30.Over 60, and gas planets have more, because of their immense gravity
31.Of course. Our moon did at one time, and Io does.
32.Venus
33.Neptune
34.Mercury, but skip this one.
35.Venus
36.Plate tectonics
37.Increased heat is trapped on the planet surface by an excess of methane, carbon dioxide and water vapor.
38.See your notes, and compare the Earth to Mars, as you will have to do on the test tomorrow.
39.Pluto, and his method of finding that Plutoid is used to help determine asteroid locations today. Tombaugh used glass plates.
40.Rivers changing course, fence posts leaning, and craters disappearing.
41. Surfaces with no wind or water will have minimal weathering, which explains the moon.
