Question

The moon is ____ when the earth,the moon and the sun make 90 degree

Answer 1

The Moon is 90 degrees—at a right angle—from the Sun. If you face the first-quarter moon when it is high in the sky, sunlight will shine on the right side of your head and the right side of the Moon. You see more of the Moon as it moves along its orbit during the second week.

When the Sun and Moon form a right angle with respect to Earth, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. This happens at 06:00 a.m. and 06:00 p.m.
