Which picture shows when the moon has completed one half of its

orbit around the Earth.

Select the photo that demonstrates what happens when the moon is directly between the sun and Earth. The side facing the Earth is in darkness.

Which photo shows the appearance of the moon when it has completed three quarters of its orbit around the Earth?

The darkened side of the moon begins to reappear after the full moon:

As the moon begins to move in its orbit around the Earth, a sliver of the illuminated

side of the moon becomes visible.

Select the correct phase when the moon has completed one quarter of its orbit around the Earth.

Select the correct photo of the moon as nears the end of its orbit, and the moon

appears as a crescent shape once again.

Select the picture which shows the phase where a portion of the illuminated side of the moon is

visible from the Earth as it continues to increase.

Sorry, wrong answer. Please click on the sad face to guess again.

New Moon - The Moon's unilluminated side is facing the Earth. The lighted side of the Moon faces away from the Earth.  This means that the Sun, Earth, and Moon are almost in a straight line, with the Moon in between the Sun and the Earth.  The Moon that we see looks very dark.

Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight.  The crescent will grow larger and larger every day, until the Moon looks like the First Quarter Moon.

First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The right half of the Moon appears lighted and the left side of the Moon appears dark. 

Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight.  ("Waxing" means increasing, or growing larger.)

Full Moon - The Moon's illuminated side is facing the Earth. The lighted side of the Moon faces the Earth.  This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle.  The Moon that we see is very bright from the sunlight reflecting off it.

Waning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. ("Waning" means decreasing, or growing smaller.)

Last Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The left half of the Moon appears lighted, and the right side of the Moon appears dark.  It will continue to shrink.

Waning Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight.  The crescent will grow smaller and smaller every day, until the Moon looks like the New Moon.
