The Foundations of Astronomy
1.1 True/False Questions
1) The distances to bodies in the solar system are a few light minutes to light hours.
Answer: TRUE
Diff: 2
Section Ref: 1.1
2) A light-year is a measurement of time.
Answer: FALSE
Diff: 1
Section Ref: 1.1
3) It was Aristotle who used the scientific method to show the Earth was a sphere.
Answer: TRUE
Diff: 2
Section Ref: 1.2
4) Constellations are close clusters of stars, all at about the same distance from the Sun.
Answer: FALSE
Diff: 1
Section Ref: 1.3
5) From the South Pole, Polaris would appear directly overhead.
Answer: FALSE
Diff: 1
Section Ref: 1.3
6) Only at the equator are all the stars visible over the course of the year.
Answer: TRUE
Diff: 1
Section Ref: 1.3
7) Over the course of a night, Polaris moves less than any other visible star in the sky.
Answer: TRUE
Diff: 2
Section Ref: 1.3
8) There are 3,600 arc seconds in a degree.
Answer: TRUE
Diff: 2
Section Ref: More Precisely 1-1
9) At apogee, the Moon is at its farthest from Earth and thus appears smaller than normal.
Because of this it can produce only annular solar eclipses, but not total solar eclipses.
