What Are the Phases of the Moon
The phases of the moon are the changing shapes of the moon as seen from Earth. They result from the moon's position in its orbit around Earth, which changes how much of the sunlit side we can see.
How Nature Uses Moon Phases
In nature, moon phases influence tides, animal behavior, and seasonal rhythms. The gravitational pull of the moon drives ocean tides, while many species use moonlight for migration, feeding, and reproduction.
Quick Overview of the Main Moon Phases
The main phases are new moon, first quarter, full moon, and last quarter. Between these primary phases, the moon passes through waxing and waning crescents and gibbous stages. For a detailed diagram of each phase, see NASA Moon Phases.
