Question
Chapter 2, Problem 22Q
To determine
(a)
Thesketch for the case when an observer is located at the North Pole.
To determine
(b)
The sketch for the casewhen an observer is located at the equator.
To determine
(c)
The justification of the rule that states, “The latitude of an observer in the northern hemisphere is equal to the angle in the sky between that of the observer’s horizon and the north celestial pole.”, which was in use by the navigators since long.

Some Canadians troups are sent (as part of a U.N. peacekeeping force) to a country located on the Earth's equator.
At night, when homesickness makes them gaze sleeplessly at the stars, which of the following will be familiar to them (the same as the equator in Canada)
1. The celestial poles are on the north and south points of the horizon.
2. The celestial equator is overhead and passes through the zenith.
3. All stars rise and set ( no star in the sky all night long)
4. All stars are above the horizon exactly half a day.
5. None of the Above
A graduate student in geology who grew up in Florida (in the southern most tip of the United States) gets to accompany her research professor to the North Pole.
What will be different at the North Pole from the way she remembers the sky in Florida?
1. A celestial pole is overhead
2. The celestial equator is on the horizon
3. The way (and whether) the stars rise and set
4. All of the above would be different as it is in Florida

- Based on what you've learn on the impact of the Earth-Sun distance on the seasons, what can you say about the the cause of the seasons?
