Correct Option
The correct option isPlaces beyond the Arctic Circle experience continuous daylight.
Explanation
On 21st June, the Earth is in a position known as the Summer Solstice. During this time, the Northern Hemisphere is tilted towards the Sun, resulting in maximum insolation in this hemisphere. The Sun's rays fall vertically on the Tropic of Cancer ($23.5^\circ$ N).
Option Analysis
- The rays of the Sun fall directly on the Tropic of Capricorn. is Incorrect: On 21st June, the rays of the Sun fall directly on the Tropic of Cancer. The Sun's rays fall directly on the Tropic of Capricorn during the Winter Solstice (around 22nd December).
- Places beyond the Arctic Circle experience continuous daylight. is Correct: Due to the tilt of the axis, the North Pole is inclined towards the Sun. Consequently, the regions beyond the Arctic Circle ($66.5^\circ$ N) receive sunlight continuously, experiencing daylight for the entire 24-hour period.
- It is winter season in the regions north of the equator. is Incorrect: Since the Northern Hemisphere receives direct sunlight and longer duration of daylight, it experiences the summer season. The Southern Hemisphere experiences winter during this period.
- Nights are longer than days. is Incorrect: In the Northern Hemisphere, days are longer than nights during the summer season. The longest day and the shortest night occur on 21st June.
Key Takeaway
Summer Solstice (21st June): The Northern Hemisphere tilts towards the Sun, the Sun is overhead at the Tropic of Cancer, days are longer than nights in the Northern Hemisphere, and areas beyond the Arctic Circle experience continuous daylight.
