* Sunlight: The Sun is a giant ball of hot gas that emits light and heat.
* Reflection: The Moon's surface is covered in dust and rocks that are rough and uneven. When sunlight hits these surfaces, it bounces off in many directions, a process called reflection.
* Illumination: We see the Moon because some of this reflected sunlight reaches our eyes. The portion of the Moon that's facing the Sun is illuminated, while the side facing away is dark.
Phases of the Moon:
The different shapes we see the Moon in, called phases, are caused by the changing angles of sunlight reflecting off its surface as the Moon orbits Earth.
* New Moon: The Moon is between the Earth and the Sun, so its illuminated side faces away from us. We can't see it.
* Waxing Crescent: A sliver of the Moon is visible as it moves out from the Sun.
* First Quarter: Half of the Moon's face is illuminated.
* Waxing Gibbous: More than half of the Moon's face is illuminated.
* Full Moon: The Moon is opposite the Sun, so its entire illuminated side faces Earth.
* Waning Gibbous: More than half of the Moon's face is illuminated, but the illuminated portion is shrinking.
* Last Quarter: Half of the Moon's face is illuminated.
* Waning Crescent: A sliver of the Moon is visible as it moves towards the Sun.
