Astronomy Exam 1 (Chapters 1-5)
A line running from due north to due south through a point directly overhead is called -
a meridian
Residents of the Southern Hemisphere cannot see the stars around the north celestial pole because -
Earth itself is in the way.
A sky observer in the southern hemisphere would see stars moving which way? -
clockwise
Is there any location on Earth where the entire sky is potentially visible within a 24 hour period
(ignoring the fact that some stars can't be seen if it is daytime)? -
At the equator
The equator is the only place on Earth where you can see the entire celestial sphere (day or night)
over the course of 24 hours. -
True
If a star rises on the eastern horizon, it will set on the western horizon 6 hours later. -
False

, The heavy elements that make up most of Earth were formed via nuclear fusion in the center of our
Sun. -
False
The Local Group is a member of the Virgo Supercluster. -
True
If a scientific theory cannot be tested, it is assumed to be true. -
False
A crucial component of a scientific theory is that it is able to be tested by observations and thus
proven true or false. -
True
On the autumnal equinox, the lengths of both day and night are 12 hours. -
True
The altitude of the Sun as it crosses the meridian changes during the year. -
True
A person who lives at the equator will see the Sun directly overhead at noon every day of the year. -
False
The seasons on Earth are caused by the change in distance between the Sun and Earth. -
False
The apparent path of the Sun across the celestial sphere during a year is called the: -
