1. Base your answer to the following question on the diagram below, which shows
sunlight entering a room through the same window at three different times on the
same winter day.
The apparent change in the Sun’s position shown in the diagram is best explained
by
1) the Sun rotating at a rate of 15 ° per hour
2) Earth’s axis tilted at an angle of 23 °
3) the Sun’s axis tilted at an angle of 23 °
4) Earth rotating at a rate of 15 ° per hour
2. Which change would occur if the Earth's rate 5. The diagram below shows the noontime
of rotation were to increase? shadow cast by a vertical post located in
1) The year would be shorter. New York State.
2) The day would be longer.
3) The year would be longer.
4) The day would be shorter.
3. If the Earth's rate of rotation decreased,
which of the following would increase?
1) The Sun's angle of insolation at noon.
2) The number of observable stars at night.
3) The length of time for one Earth day.
4) The length of the seasons.
4. The time required for one Earth rotation is
about Which letter indicates a location west of the
post?
1) one hour 2) one day
3) one month 4) one year 1) A 2) B 3) C 4) D

2. 6. The diagram below shows Earth as viewed 9. The diagram below shows the rotating Earth
from above the North Pole (NP). Points A as it would appear from a satellite over the
and B are locations on Earth's surface. North Pole.
At location A, the time is 12 noon. What is
the time at location B?
1) 6 a.m. 2) 6 p.m.
3) 3 p.m. 4) 12 midnight The time at point X is closest to
1) 12 noon 2) 6 a.m.
7. The cartoon characters below are watching
3) 12 midnight 4) 6 p.m.
the Sun set.
10. Base your answer to the following question
on the map below. The map 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.
Toward which general direction are the
characters looking?
1) south 2) west
3) east 4) north
8. The Earth's Moon is
1) sometimes closer to the Sun than it is The timekeeping system shown in the
to the Earth and sometimes closer to diagram is based on the
the Earth than it is to the Sun 1) Sun's revolution
2) about the same distance from the Sun 2) Sun's rotation
as it is from the Earth 3) Earth's revolution
3) always much closer to the Sun than it 4) Earth's rotation
is to the Earth
4) always much closer to the Earth than it
is to the Sun
