    1. 1. 1
    2. 2. The Moon 2
    3. 3. The Moon∗ Closest celestial object to the Earth∗ We can’t see the other side of the Moon called“the dark side of the Moon”
    4. 4. The Moon∗ As the Moon completes one orbit around theEarth the Moon rotates only once on its axis∗ Makes a complete orbit around the Earth in about29.5 days
    5. 5. Phases of the Moon
    6. 6. Phases of the MoonThe Moon is always half illuminated by the Sun
    7. 7. Phases of the Moon
    8. 8. Phases of the MoonHow much of the illumination we see depends onwhere the Moon is relative to Earth. Terms to know: waxing, waning, full Moon, new Moon
    9. 9. Phases of the Moon
    10. 10. Phases of the Moon
    11. 11. Phases of the Moon
    12. 12. Eclipses
    13. 13. EclipsesEclipse – the phenomenon in which one celestial object moves directly in front of another celestial object Earth’s shadow is divided into two parts: - Umbra (inner shadow) - Penumbra (outer shadow)
    14. 14. Lunar EclipseOccurs when the Earth is between the Sun and theMoonThere are an average of two lunar eclipses every year
    15. 15. Lunar Eclipse
    16. 16. Solar Eclipse∗ Occurs when the Moon is between theSun and the Earth∗ Solar Eclipses occur on average twice ayear, however can only be seen fromspecific places on Earth∗ Cannot look directly at Solar eclipse, will damage vision.
    17. 17. Solar EclipseThe diameter of the Sun is 400x larger thatthe Moon, but the Moon can cover the Sunbecause the Sun is 400x farther from theEarth than the Moon
    18. 18. Total Solar Eclipse
    19. 19. Tides
    20. 20. Tides The moon and the sun exert gravity on the earth. This causes the rise and fall of sea levels.
    21. 21. TidesSpring tides*: large tides form when the Sun and the Moonare lined up with the Earth. The amount of enhancement inEarths tides is about the same when the Sun and Moon arelined up on opposite sides of the Earth*not associated with season of spring
    22. 22. TidesNeap tides: the Sun and Moon interfere with each other inproducing tidal bulges and tides are generally weaker
