Question

The lunar eclipse takes place:
(A) on new moon night
(B) the night of a crescent moon
(C) when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun
(D) when the Earth comes between the Sun and the Moon

Answer 1

Hint: We can say that the partial or total blocking of light of one celestial object by another. An eclipse of the Sun or Moon occurs when the Earth, Moon, and Sun are aligned. In a solar eclipse the Moon comes between the Sun and Earth. An eclipse occurs when one object gets in between you and another object and blocks your view. From Earth, we routinely experience two kinds of eclipses: an eclipse of the Moon and an eclipse of the Sun. Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.

Complete step by step answer
We know that during a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon. A lunar eclipse is when the Earth passes between the Sun and Moon, casting a shadow on the lunar surface. From the Earth, we see a circular bite taken out of the Moon, a dark arc slowly growing, mimicking the crescent Moon shape. That magnificent sight is the Sun being eclipsed by the Earth as seen from the Moon.
It is known that a partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the 3 celestial bodies do not form a perfectly straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow. Though a lunar eclipse is not considered as harmful as a solar eclipse, wearing protective eye-wear while looking at the moon during this time is advised. It can protect us from harmful rays that may damage our eyesight.
So a lunar eclipse takes place when the Earth comes between the Sun and the Moon.

Hence, the correct answer is option D.

Note: We can say that in a solar eclipse, the Moon moves between the Earth and the Sun. When this happens, part of the Sun's light is blocked. The sky slowly gets dark as the Moon moves in front of the Sun. When the Moon and Sun are in a perfect line, it is called a total eclipse. Total solar eclipses produce harmful rays that can cause blindness. During a total solar eclipse when the disk of the moon fully covers the sun, the brilliant corona emits only electromagnetic radiation, though sometimes with a greenish hue. A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon. Total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth's surface traced by the Moon's full shadow or umbra.
