					The Moon
              Uniqueness
• One of the Largest Moons in solar system
• Relatively far from Earth

• Made of solid rock (instead of ice)– similar
  materials as the Earth
• Only moon among inner planets
   Temperatures on the Moon
Range from 127oC to -173oC
  Physical Surfaces

No erosion on the moon
(no atmosphere/water)

Highlands– mountainous
Maria– dark, smooth plains
Impact Craters– Formed when objects have
  crashed into the moon.
  Rays can be seen radiating out of a crater
              Impact Theory
About 4.5 billion years ago a object about the size
  of Mars collided with the Earth

Materials from the outer layers of Earth were
 thrown into space

**Scientists are unsure but these support that
  there is no water and the moon is made of the
  same materials as in the Earth’s Crust
        Phases of the Moon
Moon revolves around the Earth and the
 Earth around the sun.

The changing position of these objects
 creates different views of the moon.

The light we see from the moon is being
 reflected off the moon not created by
              New Moon
Moon is between Earth and the Sun
Sunlit side is facing away from us
No moon is seen
               Waxing
As the Moon moves around the Earth the
 portion of the lit moon increases
          Waxing Crescent
Crescent–
 under half of
 the moon is
 seen
              First Quarter
• The right half of the
  moon is seen
         Waxing Gibbous
Gibbous– over
 half of the
 moon is seen
               Full Moon
Earth is between the Moon and the Sun

All the Moon is seen
                 Waning
As the Moon moves around the Earth and
 the portion of the lit moon decreases

Crescent and Gibbous are the same

Third quarter– The left half of the moon is
 seen
Waning Gibbous
Third Quarter/ Last quarter
Waning Crescent
             Lunar Month
The time it takes for the moon to go around
 the Earth once

29.5 days
            Solar Eclipses
Moon passes directly between the Sun and
 Earth

Where you are located on Earth determines
 if you will see a full eclipse or partial

Solar Eclipses don’t happen monthly
 because of an elliptical orbit and an offset
 orbit
