does not set below the horizon at the Arctic Circle
B
does not set below the horizon at Antarctic Circle
C
shines vertically overhead at noon on the Equator
D
shines vertically overhead at the Tropic of Capricorn
Correct Answer: Option A
Explanation
1. 21st June marks the Summer Solstice in the Northern Hemisphere.
2. On this day, the Northern Hemisphere is tilted most directly towards the Sun.
3. Consequently, the Sun shines vertically overhead at noon on the Tropic of Cancer (23.5° N latitude), not the Equator (Option C incorrect) or the Tropic of Capricorn (Option D incorrect).
4. Due to the tilt, all locations north of the Arctic Circle (66.5° N latitude) experience 24 hours of daylight. The Sun does not set below the horizon at the Arctic Circle itself. Therefore, statement (A) is correct.
5. Conversely, locations south of the Antarctic Circle (66.5° S latitude) experience 24 hours of darkness. The Sun remains below the horizon all day (Option B incorrect).
