7. Base your answer to the following question on "the map below, which shows the latitude and longitude
of five observers, A, B, C, D, and E, on Earth.
"
Which two observers would be experiencing the same apparent solar time?
A) A and C
B) B and C
C) B and E
8. Base your answer to the following question on "
the map below which represents a view of the Earth
looking down from above the North Pole (N.P.),
showing the Earth's 24 standard time zones. The Sun's
rays are striking the Earth from the right. Points A, B,
C, and D are locations on the Earth's surface.
"
Areas within a time zone generally keep the same
standard clock time. In degrees of longitude,
approximately how wide is one standard time zone?
A) 7 º
B) 15º
C) 23 º
D) 30º
D) D and E
9. Base your answer to the following question on passage and time zones map shown below.
Time Zones
In 1883, Earth was divided into 24 time zones. The United States (excluding Alaska and
Hawaii) has four time zones, which are indicated by different shadings on the map.Each zone is
roughly centered on lines of longitude that are 15° apart. These lines are shown as dashed lines on
the map. Most locations within a time zone have the same time.This time is called standard time.
As you move to the west, the time in each zone is one hour earlier than the previous time zone
When it is 1 a.m. in New York City, what time is it in Denver?
Base your answers to questions 10 and 11 on the United States time zone map shown below. The
dashed lines represent meridians (lines of longitude).
10. If the time in Buffalo, New York, is 5 a.m., what time would it be in San Francisco, California?
A) 8 a.m.
B) 2 a.m.
C) 3 a.m.
D) 4 a.m.
11. The basis for the time difference between adjoining time zones is Earth's
A) 1° per hour rate of revolution
C) 15° per hour rate of revolution
B) 1° per hour rate of rotation
D) 15° per hour rate of rotation
