Question

the model below shows the moon at one position in its orbit around earth. the white half of the moon represents the part of the moon that is lit up by the sun. select the phase of the moon shown in the model. new waning gibbous waning crescent

Explanation:

The new moon phase occurs when the Moon is positioned between the Earth and the Sun. In this position, the side of the Moon illuminated by the Sun is facing away from the Earth, making the Moon invisible or nearly invisible from Earth. In the given model, the white half (illuminated part) of the Moon is not facing Earth, which is characteristic of the new moon phase. The waning gibbous has more than half of the Moon illuminated (but decreasing), and the waning crescent has a small sliver illuminated. Since the model shows no illuminated part facing Earth (similar to new moon's visibility from Earth - though in reality new moon is when Moon is in that position astronomically), among the options, the new moon is the correct choice.
