Study Notes
- The moon appears to emit light but it's an illusion, as the moon itself does not produce light.
- The moon's phases are due to the reflection of sunlight on its surface.
- The moon's orbit around the Earth causes different amounts of sunlight to be reflected, leading to different phases.
- A new moon occurs when the moon is in between the Earth and the Sun, and its side facing the Earth is not illuminated by sunlight.
- A full moon occurs when the moon's fully illuminated side is facing the Earth, allowing us to see the entire moon's surface lit up.
- The lunar cycle, or phases of the moon, takes about 29.5 days to complete.
- The moon goes through several phases as it orbits the Earth, including crescent, first quarter, waxing gibbous, last quarter, and waning crescent.
- The terms "waxing" and "waning" refer to the moon growing in size (waxing) and shrinking in size (waning).
