The cause of seasons
tilt of Earth's rotation axis
phase during a solar eclipses
what is a new moon
what astronomical body causes Earth's ocean to rise and fall twice each day

sun - earth- moon
lunar eclipse
nearest star to Earth
What is the Sun
December 21 or 22

day when Earth's rotation axis is leaning along Earth's orbit, neither toward nor away from the Sun
Equinox
1st quarter
higher high tides and lower low tides
spring tides
when can you not see a solar eclipse
if you are outside the umbra or penumbra
spinning motion
what is rotation
this makes Earth's colder at the poles and warmer at the equator
tilt of Earth's curved surface
only 25 % of the moon can be seen during this phase as the moon is trying to become a full moon
waxing crescent
When is the moon's gravity slighty stronger
side of Earth closer to the moon
This occurs when only a part of the Moon passes through Earth's umbra
partial lunar eclipse
Earth's rotation axis is most toward or away from the sun
