Q20. On 21st June, the Sun:
(a) does not set below the horizon at the Arctic Circle.
(b) does not set below the horizon at the Antarctic Circle.
(c) shines vertically overhead at noon on the Equator.
(d) shines vertically overhead at the Tropic of Capricorn.
Answer: A
- 21st June is the longest day of the year as countries lying to the north of the equator, including India, witness ‘Summer Solstice’. The ‘summer solstice’ occurs exactly when the earth’s axial tilt is most inclined towards the sun at its maximum of 23 degrees 26’. During ‘summer solstice’, the Northern Hemisphere witnesses its longest day of the year while the Southern Hemisphere sees its shortest day. On the June solstice, the Earth’s North Pole is at its maximum tilt toward the sun. At this time, the sun appears directly overhead at 23.5 degrees north latitude, along the Tropic of Cancer. Around the Arctic Circle, the location of sunrise and sunset start to converge in the northern sky, until eventually the sun never sinks below the horizon. Hence, the appearance of the midnight sun.
