Explanation

June 21 marks the Summer Solstice in the Northern Hemisphere. On this day: 1. **Equator:** The Equator always experiences approximately 12 hours of day and 12 hours of night throughout the year, regardless of the season or solstice. So, it does not experience *more* than 12 hours. 2. **Tropic of Cancer:** On June 21, the sun is directly overhead at the Tropic of Cancer (23.5° N). All locations in the Northern Hemisphere beyond the Equator experience increasingly longer days, reaching maximum day length at the Tropic of Cancer and further north. Thus, the Tropic of Cancer experiences significantly more than 12 hours of sunlight. 3. **Tropic of Capricorn:** The Tropic of Capricorn (23.5° S) is in the Southern Hemisphere. On June 21, it is winter in the Southern Hemisphere, and locations there experience their shortest days, meaning less than 12 hours of sunlight. 4. **Arctic Circle:** On June 21, the entire region north of the Arctic Circle (66.5° N) experiences 24 hours of daylight (the 'midnight sun'). This definitely means more than 12 hours of sunlight. Therefore, the Tropic of Cancer and the Arctic Circle experience more than 12 hours of sunlight on June 21.
geography: On June 21 every year, which of the following latitude(s) experience(s) a sunlight of more than 12 hours? 1. Equator 2.
