2. Seasons notes (page 167)
• Cause:
– Tilt of the Earth’s axis (23.5 degrees) as Earth revolves
around the sun.
– The amount of sunlight and the angle of sun an specific
area is receiving
• Solstices and Equinoxes
– Solstices: when the sun’s travels seem to “stand still” then
reverse
• June Solstice (summer in N, winter in S)
• December Solstice (winter in N, summer in S)
– Equinoxes: equal amounts of daylight and night time hours
• March Equinox (spring/vernal in N, fall/autumnal in S)
• September Equinox (fall/autumnal in N, spring/vernal in S)

3. Page 168: What causes moon phases?
• We always see the same side of the moon.
But, the moon both revolves and rotates. How
can we explain why we only see one side of
the moon?
– The Real Reason: The moon rotates at the same
rate it revolves around the Earth, so we only see 1
side. (About 28 days each)
