Which solstice occurs around December 21?

• A. Summer Solstice
• B. Vernal Equinox
• C. Autumnal Equinox
• D. Winter Solstice

Answer: (D)

Solstices are the two times each year when the Sun’s path in the sky reaches its extreme height or lowest point because the Earth is tilted on its axis. Around December 21, the tilt is such that the Northern Hemisphere is tilted away from the Sun, making the Sun appear lowest at noon and resulting in the shortest day of the year. This is the winter solstice. After this date, days begin to lengthen as the Sun climbs higher in the sky toward spring. (In the Southern Hemisphere, the situation is reversed, and December 21 is their summer solstice.)
