Some questions may require the use of the Earth Science Reference Tables.
Base your answers to
questions 1 through 5 on the diagram below. The diagram
represents the apparent path of the Sun observed at four locations on the Earth’s surface
on March 21. The present positions of the Sun, Polaris, and the zenith (position directly
overhead) are shown for an observer at each location.
1.
The observer at location A casts a shadow at the time represented in the diagram.
a.
State the compass direction in which the observer at location A must look
to view her shadow. [1]
b.
Describe the change in the length of the shadow that will occur between
the time shown and sunset. [1]
2.
State the approximate time of day for the observer at location B when the Sun is at the
position shown in the diagram. [1]
3.
Explain why the intensity of sunlight at noon on March 21 is greater at location C
than at other locations. [1]
4.
The observer at location D is located at a higher altitude than the other three
observers. State one
way that this conclusion can be determined from the diagram. [1]
5.
State the other day of the year when the Sun’s apparent path is exactly the same as
that shown for these four locations on March 21. [1]
