Lunar cycle

  1. 1. The Lunar Cycle
  2. 2. Light seen from the moon is reflected sunlightAs moon moves around earth, different parts of it areilluminated and visible to usDifferent shapes of reflected sunlight are called phases
  3. 3. Phases of the MoonNew moon – when moon is between sun and earthand not illuminated (it’s dark)
  4. 4. Phases of the Moon Waxing – name used whenthe lit part of moon isincreasing Waxing-crescent phase –when a sliver of moonbecomes visible
  5. 5. Phases of the MoonFirst-quarter – when the waxing moon becomes ahalf-circlecalled “first-quarter” because moon is a quarter of the wayin it’s orbit
  6. 6. Phases of the MoonWaxing – gibbous – when the visible portion of themoon is larger than a half-circle and is increasing
  7. 7. Phases of the Moon Full moon – when the moonappears as a full circle Earth is between the moonand sun
  8. 8. Phases of the MoonWaning – when the lit part of the moon is decreasingWaning-gibbous – lit part of moon still bigger thanhalf-circle but shrinking
  9. 9. Phases of the Moon Last-quarter - when thewaning moon becomes a half-circle called “last-quarter”because moon is at the lastquarter of the way in it’sorbit
  10. 10. Phases of the MoonWaning-crescent - when a sliver of moon is all that’svisible moon moves into “new moon” phase afterwaning crescent to begin cycle again
  11. 11. Earthshineon either side of a new moon, the darkened part ofmoon is slightly visible – “earthshine”
