4. Moon & Its Effects One-fourth of the Earth’s diameter; 1/80 th of Earth’s mass (approximately 1.23%) Revolves around the earth every 29 1/2 days The gravity of the moon controls the tides

5. Positions of the Moon, Earth & Sun Cause… Phases of the moon Eclipses Tides

6. 8 Phases of The Moon New moon Waxing Crescent First Quarter Waxing Gibbous Full moon Waning Gibbous Third Quarter Waning Crescent

7. What Causes the Phases of the Moon? The moons does not glow, it reflects light from the sun. This is why the moon appears to shine bright. The part of the moon facing the sun is always lit up. The part facing away from the sun is always dark. The different phases depend on how much of the sunlit side of the moon faces Earth.

9. Moon Phases NEW MOON WAXING CRESCENT 1 st QUARTER WAXING GIBBOUS FULL MOON WANING GIBBOUS 3 rd QUARTER WANING CRESCENT The term “Waxing” means the moonlight is “increasing” so the light is to the right side of the moon.

10. Moon Phases The term “Waning” means the moonlight is “decreasing” so the light is to the left side of the moon. NEW MOON WAXING CRESCENT 1 st QUARTER WAXING GIBBOUS FULL MOON WANING GIBBOUS 3 rd QUARTER WANING CRESCENT

11. New Moon The moon is not visible from Earth. The moon is between the Sun and the Earth. The dark side is facing us. This phase lasts one night.

12. Waxing Crescent Waxing means that the bright side is increasing. The right side is the bright side. Less than one half of the moon is lit up. This phase includes any visible moon from a small sliver to almost half.

13. First Quarter or Half Moon The entire right side of the moon is lit up. The moon looks like a half circle. The lit up side is increasing. This phase only lasts one night.

14. Waxing Gibbous Gibbous means that more than one half is visible, but it is not quite full. This phase includes the night after the first quarter to the night before the full moon.

15. Full Moon The moon is full and bright. It looks like a large circle. The lit up side is facing us. Only happens one night per lunation (moon phase cycle).

16. Waning Gibbous The moon appears more than half but not quite full. Waning means that the lit up side is decreasing. The left side is the bright side.

17. 3 rd Quarter or Last Quarter/ Half Moon Left Half of the moon is lit. The lit side is decreasing. This phase also only lasts for one night.

18. Waning Crescent Less than one half of the moon is lit up. The moon will continue to become smaller and smaller.

20. What are the phases of the moon? The phases of the moon depend on how much of the sunlit side of the moon faces Earth New Moon Waning Crescent Waxing Crescent 1 st Quarter Waxing Gibbous Waning Gibbous 3 rd Quarter Full Moon What does waxing mean? What does waning mean? MOVIE

21. How are tides formed? Tides occur mainly because of differences in how much the moon pulls on different parts of the Earth The pull of gravity from the moon and sun causes the rise and fall of water on Earth - Solar Tides - Lunar Tides MOVIE
