The document discusses the phases of the Moon. As the Moon revolves around the Earth, the angle of sunlight hitting its surface changes, which causes it to appear to go through eight phases in a cycle that takes approximately one month. The phases include new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. The Moon does not produce its own light but rather reflects sunlight, making it visible from Earth.

1. Phases of the Moon

2. The Earth’s Moon

The Earth’s moon is a natural satellite. Although it
appears bright, the moon does not actually produce its
own light. Instead, it reflects the sun’s rays which makes
it visible.

3. Phases on the Moon

The moon is in a constant rotation around the Earth. As it
revolves, the angle at which the Sun’s rays reflect off of
its surface changes what is visible to us. The entire cycle
of moon phases takes about one month to complete.

4. New Moon

The moon is not visible in the sky. Except during a solar
eclipse. In the picture below there appears to no moon,
however, the moon is simple not being laminated by the
sun’s rays.

5. Waxing Crescent

The moon is less than one-half illuminated by the sun but
less than one quarter illuminated. Occurs when the moon's
illumination is increasing

6. First Quarter

The moon is one-half illuminated by the sun. Occurs when
the moon's illumination is increasing

7. Waxing Gibbous

The moon is more than one-half illuminated by the sun
but not completely illuminated. Occurs when the moon's
illumination is increasing

8. Full Moon

The moon is totally visible in the sky. Except during a
lunar eclipse

9. Wanning Gibbous

The moon is more than one-half illuminated by the sun
but not completely illuminated. Occurs when the moon's
illumination is decreasing

10. Third Quarter

The moon is one-half illuminated by the sun. Occurs when
the moon's illumination is decreasing

11. Waning Crescent

The moon is less than one-half illuminated by the sun but
less than one quarter illuminated. Occurs when the moon's
illumination is decreasing

12. Full Cycle

13. Summary

The moon constantly revolves around
the sun

It does not produce its own light and
is only visible because it reflects the
light from the sun.

The moon completes a cycle of 8
phases

The full cycle takes approximately
one month
