What term describes the sun's position in the sky at the meridian when local time is 12 noon?

• A. Analemma
• B. Geostenography
• C. Vinylite
• D. Gelatin

Answer: (A)

Analemma describes the sun’s position in the sky when you observe it at the same clock time (usually solar noon) across the year. Because Earth’s axis is tilted and its orbit is not a perfect circle, the sun’s noon position on the meridian shifts in two ways: the sun’s declination changes with the seasons, and the actual solar noon time shifts slightly due to the equation of time. If you plot the sun’s position on the meridian at 12:00 each day over the year, these combined effects trace out a figure‑eight path in the sky—the analemma. The other terms aren’t related to this concept, so analemma is the correct choice.
