Question

se 4: Phases of the Moon Everyone has seen the Moon, which is a natural satellite that orbits the Earth. As the Moon rotates around the Earth it is exposed to various amounts of light from the Sun. The reason for this is simple, the Moon at night because it is reflecting light produced by the Sun and because the Earth is slightly out of the direct line of sight between the Moon and Sun. If it were not, a lunar eclipse would occur. Essentially half of the Moon is illuminated by the Sun, but because of its rotation around the Earth we do not all witness the full" illumination. The Moon also rotates around its axis, but it does so very slowly and thus one side is always facing the Earth. It takes the Moon time it takes to make one complete orbit around the Earth. However, because the Earth is also moving during that time period, it actually takes 29.3 days for it to arrive at the same position again. This is also one complete cycle of lunar phases. The lunar phases represent the amount of sunlight that the Moon receives or reflects relative to its position or orbit around the Earth. Lunar is required that the Moon receives full light from the Sun. For this to occur, the Moon must be directly opposite the Sun, with the Earth slightly out of the direct line of sight. Therefore, the full Moon rises in the east around sunset, reaches the halfway point in its orbit in the ecliptic around midnight, and sets around sunrise.

Answer 1

A. If the Moon is full, approximately at 6 PM the Sun set and the Moon rise in the sky.

B. In the New Moon phase, the Moon is placed between the Sun and Earth, then the dark side of the moon faces to us.

C. A Quarter Moon is always 45° of a circle away from the Sun as shown in the below figure.

D. When the Moon passes directly behind Earth and into its shadow, then Lunar eclipse is seen. A lunar eclipse can be seen only on the night of a full moon when the Sun, Earth, and Moon are at a straight line and the Earth is placed between the Sun and Moon, then the Shadow of the Earth makes Lunar Eclipse.

Similarly at the day time when the Sun, Earth, and Moon are at a straight line and the Moon is placed between the Sun and Earth, then the Shadow of the Moon makes Solar Eclipse.
