Question

give the relative position of Sun Moon and Earth on the full moon day and on the new moon day on the following day the new moon day how does the size of the illuminated part of the Moon changes also name the term used for the Apparent size in

Answer 1

As the Moon orbits around the Earth, the half of the Moon that faces the Sun will be lit up. The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon. Each phase repeats itself every 29.5 days.

The same half of the Moon always faces the Earth, because of tidal locking. So the phases will always occur over the same half of the Moon's surface.

A phase is an angle of the moon to the earth so it appears differently every day.
