FOUR MAIN SHAPES FULL CRESCENT Four Basic Shapes GIBBOUS QUARTER
Like the earth, half of the moon is always lit by the sun. • Also like the Earth, half of the moon is completely dark. • The moon does not really change, it travels around the Earth. • The different shapes that we see are different views of the same side of the moon. • Sometimes we cannot see the new moon at all!
New Moon • When the moon is in between the sun and the Earth, we cannot see the moon. This part of the moon is in the shade. • This is called a new moon.
Full Moon • When the Earth is in between the moon and the sun, we see the whole part of the moon which is lit up by the sun. • This is called a full moon.
Quarter Moon • When the moon is above or below the Earth, we can only see half of the lit area of the moon. • This is called a quarter moon.
Crescent Moon • When the moon is in between the new moon and the half moon, we are only able to see a little sliver of the lighted side of the moon. • This is called a crescent moon.
Waxing and Waning • New moon • Waxing Crescent moon • First Quarter moon • Waxing Gibbous moon • Full moon • Waning Gibbous moon • Third Quarter moon • Waning Crescent moon • New moon
As the moon grows larger, towards becoming a full moon, it is called a waxing moon. • Right side of moon is lit
As the moon grows smaller, away from being a full moon, it is called a waning moon. • Left side of Moon is lit
