1. THE MOON’S EFFECT ON EARTH

2. LUNAR
- RELATED TO THE MOON FROM LATIN, “LUNA”, MEANING “MOON”

3. ORBIT ONE REVOLUTION AROUND ANOTHER BODY
REVOLUTION: one object moves around another in a path similar to a circle
ROTATION: an object spinning around its axis
The moon revolution per MONTH

4. THE MOON’S ORBIT TIDAL LOCK
THE MOON ROTATES AT THE SAME RATE IT REVOLVES DAYS relative to Earth’s position with the Sun)
THE SAME SIDE OF THE MOON IS ALWAYS FACING THE EARTH
we only see one side of the moon

5. THE MOON’S ORBIT THE MOON’S ORBIT IS TILTED
NOT ON SAME PLANE AS EARTH’S ORBIT AROUND THE SUN
This is why eclipses are so rare.

6. THE MOON’S ORBIT ELLIPTICAL EARTH IS AT ONE FOCAL POINT
Sometimes the Moon is closer…

8. MOON PHASES
THE SHAPE OF THE ILLUMINATED (LIT) PORTION OF THE MOON AS SEEN FROM OBSERVERS ON EARTH

9. New Moon

10. Waxing Crescent

11. 1st Quarter

12. Waxing Gibbous

13. Full Moon

14. Waning Gibbous

15. 3rd Quarter

16. Waning Crescent

17. New Moon

18. NEW Moon
NEW = we cannot see any of the moon (the shadow side is facing Earth)

19. Waxing Crescent WAXING = Lit portion is increasing
CRESCENT = Smaller than Quarter

20. 1st Quarter
QUARTER = we can see ¼ of the moon

21. Waxing Gibbous WAXING = Lit portion is increasing
GIBBOUS = Bigger than Quarter

22. Full Moon FULL = we can see 2/4 of the moon
(the lit side is facing Earth)

23. Waning Gibbous WANING = Lit portion is decreasing
GIBBOUS = Bigger than Quarter

24. 3rd Quarter
QUARTER = we can see ¼ of the moon

25. Waning Crescent WANING = Lit portion is decreasing
CRESCENT = Smaller than Quarter

26. NEW Moon
NEW = we cannot see any of the moon (the shadow side is facing Earth)

27. ECLIPSES
One object blocks the light from the sun so another object is in shadow

29. SOLAR ECLIPSE Moon blocks light from Sun (can’t see Sun)
Moon’s shadow appears on Earth’s surface

30. LUNAR ECLIPSE Earth blocks light from Sun (can’t see moon)
Earth’s shadow appears on Moon

31. TIDES
The daily rise and fall of sea level caused by the gravitational pull of the moon

33. Tides
