Astronomy 1010 Final Exam GSU Questions
With Correct Answers
Planetary ___ have common plane and direction, low eccentricity; -
| | | | | | | | | |
CORRECT ANSWER✔✔-orbits |
___shows similar order; - CORRECT ANSWER✔✔-Rotation
| | | | |
Moons have similar ___. - CORRECT ANSWER✔✔-motions
| | | | | |
Orbital spacing ___random. - CORRECT ANSWER✔✔-not
| | | | |
Terrestrial and Jovian planets show ___ and composition - CORRECT
| | | | | | | | | |
ANSWER✔✔-trends in size | |
The collapse of an interstellar cloud. As the cloud contracts, it rotates
| | | | | | | | | | | |
faster, and the outer parts flatten into a disk. This can be observed
| | | | | | | | | | | | |
happening elsewhere in our Galaxy today. As disk cools, solid grains
| | | | | | | | | | |
form; more volatile ices found only in the outer part. Accretion of grains
| | | | | | | | | | | | |
(sticky collisions) produce planets; - CORRECT ANSWER✔✔-The collapse

Jovian planets grow even larger by attracting ___abundant gases. -
| | | | | | | | | |
CORRECT ANSWER✔✔-cold |
Many extrasolar planets (orbiting other stars) have been found in the
| | | | | | | | | | |
last decade by ___ techniques. Most are "hot Jupiters" but this is
| | | | | | | | | | | |
probably a selection effect. - CORRECT ANSWER✔✔-Doppler or transit
| | | | | | | |
Factors influencing the odds of life as we know it include the number of
| | | | | | | | | | | | | |
stars, the fraction like the Sun, fraction not binary or multiple, fraction
| | | | | | | | | | | |
with planets, and the number of nice planets per star. Harder to
| | | | | | | | | | | |
quantify factors: origin of life, intelligence, and survival. - CORRECT

There is ___ that would satisfy an astronomer that other civilizations
| | | | | | | | | | |
have visited us as "UFOs". - CORRECT ANSWER✔✔-no evidence
