All Things Being Equal? Discussion of CQ #3
Some of you noticed on the Equinox that many locations did not appear to have exactly twelve hours of equal day and night. So we asked you "Why don't all locations appear to have EXACTLY twelve hours of day and night on the Equinox?"
Congratulations to St. John Greek School Group 3 in Florida, which concisely and correctly answered that: "There are several reasons why not all places on Earth receive 12 hours of daylight and night during the Equinox. One of these reasons is because photoperiod may be seen and recorded improperly. Another reason is that refraction of the sunlight through the atmosphere can cause a distorted image, affecting sunrise and sunset times."
