On June 21st which location will be receiving 24 hours of daylight?

• A. Arctic Circle
• B. Equator
• C. Tropic of Cancer
• D. Antarctic Circle

Answer: (D)

On the June 21st solstice, the tilt of Earth's axis toward the Sun means the Sun stays above the horizon all day for locations north of the Arctic Circle. That boundary, around 66.5°N, marks where you get 24 hours of daylight at this time of year—the midnight sun. The Antarctic Circle, by contrast, experiences 24 hours of daylight around its summer solstice in December, not June. The Equator has about 12 hours of daylight year-round, and the Tropic of Cancer is simply the latitude where the Sun is directly overhead at noon on the solstice, not a location with continuous daylight. So the place receiving 24 hours of daylight on June 21st is the Arctic Circle.
