Base your answer(s) to the following question(s) on the graph
below, which shows the maximum altitude of the Moon,
measured by an observer located at a latitude of 43 N during
June in a particular year. The names and appearance of the four
major Moon phases are shown at the top of the graph, directly
above the date on which the phase occurred.
12.
Base your answer(s) to the following question(s) on the diagram
below, which shows the altitude and apparent position of the
noontime Sun, as seen from various latitudes on Earth on
a particular day of the year. Letters A through D represent
locations on Earth's surface.
Which season will begin at 41 N latitude, three months after
the date represented by this diagram?

Base your answer(s) to the following question(s) on the diagram
below, which shows Earth's orbit around the Sun as viewed from
space. Earth is shown at eight di erent positions labeled A
through H. Earth's North Pole, Arctic Circle, and equator have
been labeled at position C. The arrows show the direction of
orbital motion.

Base your answer(s) to the following question(s) on the diagram
below which shows Earth as viewed from space on December 21.
Some latitudes are labeled.
December 21
Place an X at a location on Earth's surface where the Sun was
directly overhead at some time on December
