Transcript: At the summer solstice in the northern hemisphere, the northern pole of the Earth is tilted as much towards the Sun as it can. The Sun is overhead at noon at the Tropic of Cancer, the Sun never sets north of the Arctic Circle, and the Sun never rises south of the Antarctic Circle. At winter solstice, December 22, the northern pole of the Earth is tilted as far away from the Sun as it can be. The Sun is overhead at noon at the Tropic of Capricorn, the Sun never sets south of the Antarctic Circe, and the Sun never rises north of the Arctic Circle. The midpoints between the winter and summer solstices are called the equinoxes, spring equinox March 21, fall equinox September 21. At these times, the Sun is overhead at noon the equator and the Sun is just visible at the north and south poles of the Earth’s surface.
