At which line of latitude do the Sun's rays vertically strike during the December Solstice?

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

Answer: (C)

During the December Solstice, which occurs around December 21st or 22nd each year, the Sun's rays strike the Earth most directly at the Tropic of Capricorn. This line of latitude is located at approximately 23.5 degrees south of the Equator. On this date, the Southern Hemisphere is tilted toward the Sun, resulting in the Sun being at its highest point in the sky for locations at this latitude. Consequently, areas south of the Tropic of Capricorn experience longer daylight hours while the Northern Hemisphere experiences shorter days. Understanding the positioning of the Earth relative to the Sun during the solstices is crucial for grasping concepts related to seasonal changes and sunlight distribution across the globe.
