How do the phases of the moon occur?

Answer 1

The moon is always 50% illuminated by the sun ... (just as Earth is).
But as the moon revolves through various positions in its orbit around Earth,
the portion of that 50% that's visible from where we are changes continuously.

Answer 2

The moon appears in different shapes throughout the month because it is in a different position between the earth and the sun. The phases occur because the sun reflects off of only part of the moon.

Answer 3

As the moon orbits the earth, it moves from west to east. Its position relative to the sun also changes and as a result, we see different lunar phases. The sun lights half of the moon at all times. The moon's phase that we see depends on how much its sunlit hemisphere is facing earth.

Answer 4

The phases of the moon occur because of its changing position relative to the sun and Earth. As the moon orbits Earth, different amounts of its illuminated half are visible from Earth, leading to the various phases such as full moon, new moon, and crescent moon.

Answer 5

because the moon is at a diiferent angle tword or away from the sun as it rotates. the more sun the moon gets at night the more we see it on Earth

Answer 6

This is because only parts of the moon receives light as moon moves. Seeing rest of the light is covered by Earth. There are lots of models out there, probably on internet as well, take a look
