How are new moon and full moon formed?

Answer 1

50% of the moon is always illuminated by the sun (although which 50% it is keeps changing as the moon rotates). New Moon occurs when we look directly at the entire dark half of the moon. Full Moon occurs when we look directly at the entire lighted half of the moon. Of course, we can't travel around the moon to look at different parts of it, so the moon obligingly moves around US, once every 27.32 days.

Answer 2

A new moon occurs when the Moon is positioned between the Earth and the Sun, with its illuminated side facing away from Earth. This alignment causes the side of the Moon facing Earth to be in shadow, appearing as a dark silhouette in the sky. In contrast, a full moon occurs when the Earth is positioned between the Sun and the Moon, allowing the side of the Moon facing Earth to be fully illuminated by the Sun, resulting in a bright, circular appearance in the night sky.

Answer 3

because of the sun's light
