Title: The Phases of the Moon


1
The Phases of the Moon
2
The moon is the earths only natural satellite.
3
Why are there phases? The moon orbiting around
the earth makes the moon look as though it is
changing shape in the sky. It is actually just
changing location in relationship to the
moon,earth and sun. In addition, the moon is not
creating any of its own light, but reflecting the
light of the sun.
4
How long does it take to get through all of the
phases?
  • A complete cycle of the moons phases takes 29.5
    days.

5
New Moon This is the first phase of the moons
cycle. This phase occurs on Day 1. During this
phase of the moon the illuminated side of the
moon is not visible.
6
Waxing Crescent The next phase is the Waxing
Crescent. At this point the visible portion of
the moon is waxing, or becoming larger. This
phase occurs on the 4th day of the cycle.
7
First Quarter On the 7th day of the moons cycle
the First Quarter moon occurs.
8
Waxing Gibbous The next phase is the Waxing
Gibbous and occurs on the 10th day.
9
Full Moon Following the Waxing Gibbous is the
Full Moon which occurs on the 14th day. During
this phase the Moon appears to be completely
illuminated by the sun.
10
Waning Gibbous After the Full Moon a Waning
Gibbous occurs on the 20th day. At this point
the visible portion of the moon is waning, or
getting smaller.
11
Last Quarter On the 22nd day the Last Quarter
Moon occurs. The visible portion of the moon
continues to wane.
12
Waning Crescent On the 26th day the moon is in
the Waning Crescent phase. It will continue to
wane until it reaches the New Moon phase and the
cycle starts all over.
13
Blue Moon When two full moons occur in one
calendar month it is called a Blue Moon.
14
Harvest Moon A Harvest Moon is the Full Moon that
occurs closest to the autumnal equinox, in
September when the day and night are equal in
length.
15
Hunters Moon
  • A hunters moon is the first full moon after the
    Harvest Moon

16
Why is the moon so important?
  • It is the moons gravitational pull on the earth
    that causes the tides of the ocean. Without it
    life could not exist!!

17
Lunar Eclipses
  • Lunar eclipses occur only during a full moon when
    the moon is on one side of the Earth and the sun
    is on the other side. They are lined up and the
    Earth blocks the suns rays.

18
Solar Eclipse
  • A solar eclipse occurs when the moon passes
    between the Earth and the sun when the three
    bodies are aligned. The moon completely blocks
    Earths view of the sun.

19
Dark Side of the Moon
  • We only see one side of the moon. That is
    because both the earth and the moon rotate on
    their axis at the same speeds

20
Phases
  • The moon waxes (grows) and wanes(gets smaller)
    from right to left.
