Question

How do phases of moon occur ?


Please help very urgent ​

Answer 1

Explanation:

The Moon itself does not generate light; it is lit up by the Sun. As the Moon orbits the Earth, the portion of illuminated Moon that we see changes – giving rise to the phases of the Moon. ... Once it reaches the Full Moon phase, it then seems to decrease in illumination until we reach the New Moon again after one month.

Answer 2

Answer:

Phases of moon

Explanation:

Moon phases are determined by the relative positions of the Moon, Earth, and Sun. We see the Moon go through a changing cycle of phases each month due to its orbital motion around Earth and the changing geometry with which we view it. Instead, the Moon's phase depends only on its position relative to Earth and the Sun.
