Intro to Astronomy - Practice

Name_____________________

For multiple choice questions, write your letter in the blank AND circle the letter.

1. List the Jovian planets.

2. List the Terrestrial planets.

3. ___ Asteroids are made of

A. rocky material

B. icy material

C. both

4. ___ Kuiper belt objects are made of

A. rocky material

B. icy material

C. both

5. ___ A comet's tail always points

A. in the direction it is moving

B. in the direction opposite it is moving

C. away from the Sun

D. toward the Sun

6. Planet A has only a few craters, while Planet B has a lot. Both planets formed at the same time.

Which planet has the older surface material?

7. Planet C is twice as big as Planet D. Both planets formed at the same time. Which planet would you

expect to have more craters? Why?

6. Finish this diagram of the Solar System. Include the following: the rest of the planets and their orbits,

the Asteroid Belt, and the Kuiper Belt. Your diagram does not need to be to scale (I'm looking mainly for

the order here)

.

7. During the formation of our solar system, what happened to make the protostar become a star?

8. Where did Mars' moons probably come from?

9. I will list properties and features of planets. For each property and feature, list all planets that have

that property or feature. Some will have one answer and others will have many. To receive full credit,

all answers must be given, not just one. Instead of writing out the full name of the planets use the

following:

Earth - E

Jupiter - J

Mars - M

Mercury - R (note: yes, R)

Neptune - N

Saturn - S

Uranus - U

Venus - V

(note: Y ou may write out the full planet name if you wish.)

Now here are the properties and features:

no moons ___________________________

one moon ___________________________

two moons ___________________________

more than 5 moons ___________________________

runaway greenhouse effect ___________________________

no magnetic field ___________________________

the strongest planetary magnetic field ___________________________

white ovals and brown ovals ___________________________

rocky rings ___________________________

icy and ice covered rock rings ___________________________

carbonized methane ice rings ___________________________

liquid helium and liquid metallic hydrogen layer ___________________________

methane clouds ___________________________

the most highly tilted rotation axis (98°) ___________________________

craters ___________________________

plate tectonics ___________________________

"flake" tectonics ___________________________

scarps ___________________________

volcanoes (active or inactive) ___________________________

Olympus Mons (the largest volcano in the Solar System) ___________________________

atmosphere mostly CO2 ___________________________

no atmosphere ___________________________

atmosphere mostly hydrogen ___________________________

atmosphere mostly nitrogen ___________________________

"dry ice" (CO2 ice) caps ___________________________

active geological activities ___________________________

sulfuric acid H2SO4 clouds ___________________________

unusually tilted magnetic field ___________________________

the Great Red Spot ___________________________

Valles Marineris ___________________________

evidence of ancient flowing water ___________________________

a very large difference in temperature between night and day sides ___________________________
