Moon | orbits Earth, has no atmosphere, has a rocky, dusty surface |
Moon | has no liquid water, very little ice, mountains, valleys, craters, etc. |
Moon Phases | as the moon revolves around Earth, different amounts of the surface are seen, causing these. |

Waxes | during the first half of the moon's cycle, the amount of the side of the moon seen from Earth increases or does this. |
Wanes | during the second half of the moon's cycle, the amount of the lit side of the moon seen from Earth decrease or does this. |
Calendars | are based on the movement of the Earth. |
365 days | a solar year is this many days, 5 hr., 48 min. and 45.5 sec. long (time it takes Earth to revolve around the sun). |
Leap Year | every 4 years a day is added on Feb. 29 and this is what we call it. |
