Moon’s phases, tides and other interesting facts… All About the Moon

Moon’s Effect on Earth �Tides �Eclipses

Motions of the Moon-phases �Moons rises 1 hour later every night �Moon moves eastward among the stars �Moon takes 27. 3 days to complete one cycle around the earth (revolution) �Moon takes 29. 5 days to return to its original phase when cycle started (because we are moving also) �Moon’s apparent diameter changes in a cyclic manner and is about the same apparent size as the sun

Phases of moon-one cycle � New moon � Waxing Crescent moon � Waxing Quarter moon � Waxing Gibbous moon � Full moon � Waning Gibbous moon � Waning Quarter moon � Waning Crescent moon � New moon

Why do we see phases of the moon? �We always see the same side of the moon as it orbits the earth because the moon is orbiting the earth at the same rate that it is rotating. �https: //youtu. be/6 j. Up. X 7 J 7 y. So �As it orbits us, we see the portion illuminated by the sun �http: //www. history. com/shows/theuniverse/videos/phases-of-the-moon

Tides � Caused by the gravitational pull of the moon and the sun on earth � High tide: when the earth is facing the moon � Low tide: occurs on the side of the earth not facing the moon � Spring tide: highest high tide, lowest low tide � Neap tide: lower high tide, higher low tide

The change in tides is cyclic (every 6 hours from high tide to low tide � http: //oceanservice. no aa. gov/education/kits/t ides/media/supp_tide 0 6 a. html

Eclipses � Solar Eclipse: moon blocks out the sun (sme) � Occurs in the new moon phase � Earth’s shadow falls on the moon (sem) � Occurs in the full moon phase

Solar eclipse Path of Totality: path on earth where the total solar eclipse is visible

And… �The change in size of the moon is due to its change in distance from the earth (apogee/perigee) �The change in shape of the moon is due to the phase observed of the moon �We see the phases because the moon if orbiting around the earth �The moon is illuminated by the sun

Fun Facts about the moon �Blue Moon: a blue moon is the 2 nd full moon that occurs in a month �Full moons have names- from Native American Indians- Worm Moon, Strawberry Moon etc. . �Galilieo refered to the moon a Cynthia in his anagram message to Julian de Medici when he was under house arrest-”Cynthiae figuras aemulatur Mater Amorum”-”The Phases of Cynthia are imitated by the Mother of Love”
