91
Which of the following locations would have the earliest sunrise?

60° E
Because the Earth rotates towards the east, locations further east see the sun before locations to the west.
92
The Tropic of Cancer is located at which latitude?
Answer:
23.5° North
The Tropic of Cancer is the circle of latitude at approximately 23.5° North, marking the northernmost point where the sun can be directly overhead.
93
What happens to the date when you cross the International Date Line traveling from West to East (e.g., Japan to USA)?
Answer:
You gain a day (go back in time)
Crossing the IDL from West to East means moving from the 'tomorrow' side to the 'yesterday' side, so you subtract a calendar day.
94

Latitudes
Lines of latitude are often called 'parallels' because they run parallel to the Equator and never intersect.
95
The International Date Line mostly follows which degree of longitude?

180°
The International Date Line roughly follows the 180° meridian, directly opposite the Prime Meridian.
96
If it is 12:00 PM (noon) at Greenwich (0°), what time is it at 15° East longitude?
Answer:
1:00 PM
Earth rotates from west to east. Places to the east are ahead in time. Since 15° represents a one-hour difference, 15° East is one hour ahead of Greenwich.
97
What is the primary reference line for longitude, set at 0°?
Answer:
Prime Meridian
The Prime Meridian constitutes 0° longitude and passes through Greenwich, London.
98
How many degrees of longitude does the Earth rotate in one hour?

The Earth rotates 360° in approximately 24 hours. Therefore, 360° divided by 24 hours equals 15° of rotation per hour.
99
Which imaginary line marks 0° latitude?
Answer:
Equator
The Equator is the line of 0° latitude, dividing the Earth into the Northern and Southern Hemispheres.
