▶ Answer & Explanation
Correct answer: A. does not set below the horizon at the Arctic Circle.
On June 21st, the Northern Hemisphere is tilted towards the Sun, marking the summer solstice. This results in the longest day and shortest night in the Northern Hemisphere. At the Arctic Circle (approximately 66.5° N latitude), the Sun remains above the horizon for 24 hours, an event known as the 'midnight sun'. Conversely, the Southern Hemisphere experiences winter, and the Antarctic Circle is in darkness.
