Moon Moon Phases

• The moon is Earths only natural satellite. Its
  orbit around the earth is tilted 50.

3
Moon Moon Phases

• The Earth moon revolve around each other.

4
Moon Moon Phases

• Scientists believe that the moon was formed when
  a large asteroid hit the Earth so hard, some of
  the mantle material was hurled into space.

5
Moon Moon Phases

• The moon (Luna) is a solid sphere of rocks
  dust.
• The composition of the rocks is similar to
  Earths mantle.

6
Moon Moon Phases

• The moon
• Rotates on its axis
• Has a very thin atmosphere

7
Moon Moon Phases

• The moon does not generate its own heat light.
  It reflects light from the sun.

8
Moon Moon Phases

• The moon makes 1 complete revolution around the
  Earth about every 28 days
• The moon makes 1 complete rotation about every 28
  days.

Moon Moon Phases

• Because rotation revolution occur in the same
  amount of time we only see one side of the moon
• We never see the far side of the moon

Moon Moon Phases

• Does the moon have day night? Why?

Moon Moon Phases

• The moon is about ¼ the diameter of the Earth.
• The moon Earth are about 240,000 miles apart.

12
Moon Moon Phases

• ESSENTIAL QUESTION
• IF HALF OF THE MOON IS ALWAYS LIT BY LIGHT FROM
  THE SUN, WHY DO WE NOT ALWAYS SEE ALL OF THE LIT
  HALF OF THE MOON?

Moon Moon Phases

• The moon is ½ lit all the time
• The relative positions of the Earth, moon, sun
  determine how much of the lit half we can see

16
Moon Moon Phases

• The changing shapes of the moon are called phases.

17
Moon Moon Phases

• The phases range from a new moon to a full moon
  (in about 14 days) then back to new moon (in
  about 28 days)
• This pattern repeats every 28 days

18
Moon Moon Phases

• Beginning with the new moon, the moon appears to
  get larger (waxing)
• After reaching full moon, the moon appears to get
  smaller (waning)

19
Moon Moon Phases

• Solar Eclipse happens when the moon is between
  the sun Earth. The moon casts a shadow on part
  of the Earth

20

• Solar Eclipse

22
Moon Moon Phases

• Lunar eclipses happen when the Earth is between
  the sun moon.
• The Earth casts a shadow on the moon

23
Moon Moon Phases
24
Moon Moon Phases

• The gravity between the moon Earth pulls on
  each others surface.
• The moons gravity pulls on the Earths surface
  (water land)
• Water is easier to move this causes tides in
  Earths oceans.

25
Moon Moon Phases

• The moons gravity pulls all through the earth
• The water bulges on the opposite side because of
  centrifugal force

26
Moon Moon Phases

• The position of the sun, moon Earth determine
  the tides
