Question

Which Moon is also referred to as "Dark Moon"?
A. Full Moon
B. Waning Crescent
C. New Moon
D. Waning Gibbous

Answer 1

Hint:The first primary phase of the Moon is the new Moon. It occurs when the Moon and Sun are lined up with the Earth, and the Sun becomes opposite to the Earth. Viewed from the earth, the Moon appears to vary its form nearly a day. It is nothing more than an illusion created by the Sun's position and the Earth concerning the Moon. Such illusionary aspects of the Moon are called the phases of the Moon.

Complete step by step answer:
The Moon goes to form a full revolution around the Earth in about 28 days. It takes the equal time to complete a rotation around its axis. So, every time we stare at the same side of the Moon. The Moon moves around the Earth, and therefore the Earth moves around the Sun. Due to these motions, various portions of the Moon's face towards the Earth are illuminated at different times. When the Moon's side facing the Earth reflects no sunlight, we cannot see the Moon. This is called the new Moon. The New Moon is also called a "Dark moon."

Therefore the correct option is (C).

Note:The phases of the Moon are caused by the shadow of the Sun or by the rotation of the Moon. Half of the surface of the Moon is usually illuminated by sunlight. So how much of the light we could see from our viewpoint on Earth differs every day, and we call the phases of the Moon.
