| Tides | rising and falling of the sea ocean caused by the gravity of the Moon |
| Waxing | the moon at any time after the new moon and before the full moon; the lit portion of the moon is increasing |
| Waning | the moon at any time after the full moon and before the new moon; the lit portion of the moon is decreasing |
| Full Moon | when we can see 100% of the lit up side of the moon |
