The moon

  1. 1. The Moon<br />
  2. 2. The Moon<br />The moon is essentially a chunk of earth that broke off during a collision a long time ago.<br />The Moon is as old as Earth. 4.6 billion years old. Its about the same size as Earth.<br />There is no oxygen and 1/6 the amount of gravity. The moon is held around the Earth by Gravity. This gravitational force actually causes Moonquakes<br />
  3. 3. The Moon<br />The moon does NOT actually produce its own light.<br />It is reflected sunlight that bounces off of it.<br />16. How are the Earth, Moon, and Sun arranged<br />The moon revolves around Earth.<br />As it revolves, it also rotates.<br />
  4. 4. The Moon<br />While the moon is revolving<br />around Earth, the Earth is<br />revolving around the sun.<br />Of course, as Earth revolves<br />around the sun, it also rotates.<br />
  5. 5. The Moon<br />Earth’s rotation period = 24 hours<br />Earth’s revolution period = 365.25 days<br />Moon’s rotation period = 27.3 days<br />Moon’s revolution period = 27.3 days<br />The moon rotates once on its axis<br />in the same time period it revolves<br />once around Earth.<br />We always see the same side of<br />the moon.<br />

  7. 7. Moon Phases<br />Moon phases are the changingappearance of the moon AS SEEN FROM EARTH.<br />Moon phases are caused by the Earth, Moon, and Sun being in different positions relative to each other.<br />As we look out from Earth, we can only see certain parts of the moon.<br />

  13. 13. What are the moon phases and what causes them?<br />Remember, as the moon is revolving around Earth, Earth is also<br />revolving around the sun!!!<br />The moon has to make up this extra time. Moon goes through one cycle of<br />phases in 29.5 days, or one MOONTH<br />

  15. 15. Once in a blue Moon<br />Sometimes, there are 2 new moons in the same month!!!<br />But that only happens once in a “blue moon”<br />- Moon phase = 29.5 days<br />- Average length of month = 30.5 days<br />- Sometimes we have two new moons…the lunar cycle repeats itself beforethe end of the month..<br />BLUE MOON<br />
