Why does the Moon show phases in the course of a month quizlet?
The moon appears to change shape during the course of a month because the moon orbits the Earth and moves on its own axis.

What is the causes the moon to change phases?
One important thing to notice is that exactly one half of the moon is always illuminated by the sun. So the basic explanation is that the lunar phases are created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth.

What does the moon look like one week after a new moon?

What comes 14 days after a full moon?
When the moon is illuminated from 51% to 99 %, the moon is in a “waxing gibbous phase”, so more than half of the moon is illuminated. After 14 days, the moon is now 180 degrees away from the Sun, with the Sun, Earth and Moon forming a straight line. The moon for the next 7 days will be in a “waning gibbous phase”.
How do you tell if the moon is waxing or waning?
One quick way to tell if a moon is in a waxing or waning phase is which side of the moon is the shadow on. If the shadow is on the right, like it is today, we are in a waning phase. If the shadow is on the left, then we are waxing and heading towards a full moon. An easy way to remember is to rhyme bright and right.
What happens right after the full moon phase?
After the full moon (maximum illumination), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone — a new moon.
