91.	What is the phenomenon of diamond ring?
	A. Every full Moon day
	B. Every new Moon day
	C. Solar Eclipse day
	D. Lunar Eclipse day Option “C” is correct. As the moon grazes by the Sun during a solar eclipse, the rugged lunar limb topography allows beads of sunlight to shine through in some places, and not in others. So the eclipsed Sun appears like a shining diamond ring. This is known as the diamond ring phenomenon or effect.

92.	Syzygy is –
	A. Position of Sun, Earth and Moon in a straight line
	B. Earth’s position between the Sun and the Moon
	C. Position of the Sun and the Moon on the same side of the Earth
	D. Sun Moon and Earth alignment Option “A” is correct.

93.	The reason for lunar eclipse is –
	A. Moon coming between earth and sun
	B. Sun coming between earth and moon
	C. Earth coming between sun and moon
	D. All of the above Option “C” is correct. During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. There are two kinds of lunar eclipses: 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.

94.	Lunar eclipse occurs-
	A. new Moon day
	B. full Moon day
	C. On the day of the Crescent Moon
	D. (a) and (b) above Option “B” is correct. Lunar eclipses occur at the full moon phase. When Earth is positioned precisely between the Moon and Sun, Earth’s shadow falls upon the surface of the Moon, dimming it and sometimes turning the lunar surface a striking red over the course of a few hours. Each lunar eclipse is visible from half of Earth.
