Quiz: Based on what you have learned about seasons, why is it
generally hotter in summer than in winter? Check all that apply.
Ans: The sun is higher in the sky and we have more daylight hours in
summer
Quiz: Based on what you have learned from your rankings in the last
two questions, which of the following planets would you expect to
have seasons most like Earth's?
Ans: Mars (axis tilt = 25.2°)
Quiz: Which planet has the most extreme seasons?
Ans: Uranus
Quiz: At noon, which Moon phase can be seen?
Ans: New
Quiz: When the Moon is seen as full in Seattle, what is the phase of the
Moon as viewed twelve hours later from the opposite side of the Earth?
Ans: Full
Quiz: What conditions must exist for a solar eclipse to occur?
18:36:59
,Ans: The phase of the Moon must be new and the Moon must be passing
through Earth's orbital plane.
Quiz: What conditions must exist for a lunar eclipse to occur?
Ans: The phase of the Moon must be full and the Moon must be passing
through Earth's orbital plane.
Quiz: Time spent in daylight:
A-tilt of 0
B- tilt of 23.5 up
C- tilt of 45
D- tilt of 90
E- Tilt of 23.5 down

, D- tilt of 90
E- Tilt of 23.5 down
Ans: Most to least:
D, C, BE, A
Quiz: 1. While there are many obvious aspects of the sky that change
regularly, the rapidly changing Moon is amongst the most noticeable
and significant--and fortunately, amongst the most straightforward to
understand. As clearly as you can, describe and explain both (a) the
cycle of lunar phases, and (b) total eclipses of the Sun and Moon, all as
viewed from the Earth. How are Venus' phases, as first observed by
Galileo, similar, and how are they different? You may find it helpful to
use sketches to make your points clear, but note that figures do not
replace a clear discussion of the physical geometry!
Ans: There are 8 key stages to the lunar phase. Exactly one half of the moon
is always illuminated by the sun however at most times we see a certain
portion of the sunlight and the shadowed side of the moon. The new moon
occurs when the moon is positioned between the earth and the sun. the
three objects are in "alignment". As the moon waxes the amount of the
sunlight side of the moon we can see on earth increases until the three
bodies are in alignment again and there is a full moon. At this point the moon
begins to wane and we see less and less of the sunlight side as it completes
its orbit around the earth and finally they come into alignment again and
there is another new moon. The moon exhibits synchronous rotation because
