The moon's phases are a cycle of changing appearances due to its position relative to the Earth and the Sun. It begins with the New Moon, when the side facing Earth is unlit. As it orbits, we see increasing portions illuminated, leading to the First Quarter, where half is visible. The Full Moon occurs when the entire visible side is lit. The cycle reverses until the Last Quarter, and then back to New Moon. This phenomenon helps us understand the moon's orbit and relationship with Earth.
