  1. Moon Section 19-2

  2. Motions of the Moon • Moon rotation = 27.3 days • Moon revolution = 27.3 days • Therefore, the same side of the Moon always faces Earth.

  3. Phases of the Moon • The different shapes of the Moon as seen from Earth • Depends on how much of the sun-side of the Moon faces Earth

  4. Shapes of the Moon • Crescent – small sliver • Quarter – literally ¼ of the moon • Gibbous – not quite round (humpbacked) • Full – completely visible • New – not visible, all dark

  5. Moon-phase Vocab • WAXING • In this ½ of the cycle, the visible part of the moon is getting bigger. • It is building up, like a “waxy build-up” • WANING • In this ½ of the cycle, the visible part of the moon is getting smaller • It is “waning” away

  6. We see: We see: We see: ? We see: We see: We see: We see: We see:

  7. Phases of the Moon

  8. The Lunar Cycle One full cycle of the moon = 29.5 days.

  9. Eclipses • When the moon’s shadow hits Earth or . . . • When Earth’s shadow hits the Moon

  10. Solar Eclipse • Moon is between Earth and Sun • Moon’s shadow on Earth blocks out Sun

  11. Solar Eclipse • TOTAL Solar Eclipse occurs in the UMBRA • The Umbra is the darkest part of the moon’s shadow.

  12. Solar Eclipse • PARTIAL Solar Eclipse occurs in the PENUMBRA • The Penumbra is the larger and less dark part of the moon’s shadow.

  13. Total Solar Eclipse

  14. Partial Solar Eclipse

  15. Lunar Eclipse • Earth blocks sunlight from reaching the Moon • Occurs only at full moon • Moon will look red

  16. Lunar Eclipse

  17. Next Eclipses 2008 • 2008 Feb 07: Annular Solar Eclipse • 2008 Feb 21: Total Lunar Eclipse • 2008 Aug 01: Total Solar Eclipse • 2008 Aug 16: Partial Lunar Eclipse 2009 • 2009 Jan 26: Annular Solar Eclipse • 2009 Feb 09: Penumbral Lunar Eclipse • 2009 Jul 07: Penumbral Lunar Eclipse • 2009 Jul 22: Total Solar Eclipse • 2009 Aug 06: Penumbral Lunar Eclipse • 2009 Dec 31: Partial Lunar Eclipse

  18. Tides • Caused by the gravitational pull of Moon on Earth • 2 tide cycles per day
