(Q01.01) The brightest stars in a constellation - =May actually be quite far away from each
other
(Q02.02) San Luis Obispo, CA is located at ~35N latitude. What is the altitude of the North Star
in SLO? - =35 degrees above the horizon
(Q02.01) When does a vertical flagpole in San Luis Obispo NOT cast a shadow? - =Every day at
noon; every day at the time the Sun is highest in the sky; when the Sun is highest on the
summer solstice; when the Sun is highest on the winter solstice
(NONE OF THE ABOVE)
(Q02.02) If you are located in the continental U.S. on the first day of October, how will the
position of the Sun at noon be different two weeks later? - =It will have moved to a position
closer to the horizon
(Q02.03) For an observer in the continental U.S., which of the three shadow plots shown at the
right correctly depicts the path of the Sun's shadow for one day? - =Shadow Plot A (north of
east and west)
(Q02.04) Which of the following statements is true about the location of the Sun at sunrise
during the middle of winter? - =The Sun will rise south of east
(Q02.05) Which "X" could represent the position of the end of the stick's shadow made shortly
after sunrise on Sept. 21? - =None of the above, the "X" will be directly east
(Q03.01) When it is summer in the continental U.S., it is ___________ in Australia. - =Winter
(Q03.02) Looking at the images below, which letter (a-e) best represents winter in the U.S.? -
="a" because it is facing the Sun but it is tilted away from it at the same time
, (Q03.03) The tilt of the Earth changes over the course of a year. - =False
(Q03.04) Imagine that the Earth's orbit were changed to be a perfect circle about the Sun so
that the distance to the Sun never changed. How would this affect the seasons? - =We would
continue to experience seasons in essentially the same way we do now
(Q03.05)Imagine the Earth's orbit were changed to be a perfect circle about the Sun so that the
distance to the Sun never changed. How would this affect the seasons? - =We would still
experience seasons, but the difference would be much more noticeable
(Q03.06) How many of the Earth locations shown above (A-F) would be experiencing summer? -
=Three
(Q03.07) Which of the following locations experiences the smallest amount of change in
sunlight over the course of a year? - =Equator
(Q03.08) Which of the following describes one reason that the northern hemisphere and the
southern hemisphere have different seasons at the same time? - =During the time of the year
when the Sun is high in the sky in the northern hemisphere it will be low in the sky in the
southern hemisphere
(Q03.09) If the Earth were tilted more (say 60 degrees, rather than 23.5), then during winter in
SLO, we would - =experience cooler temperatures

shown here: (waning crescent) - ="B"
