When the Sun is at one of the equinoxes,

Question

BlackTom AI · Accepted Answer

The question asks about what happens at the Sun’s position during an equinox.
Option: 'day and night are of equal length everywhere on Earth.'
To evaluate this, recall that an equinox is when the Sun appears to cross the celestial equator, resulting in roughly 12 hours of daylight and 12 hours of darkness for most locations.
However, several real-world effects modify this: first, atmospheric refraction bends sunlight as it passes through the atmosphere, making the Sun visible for a short period before sunrise and after sunset, which lengthens the apparent day slightly above 12 hours; second, the official day length is defined from sunrise to sunset for a given location, and the Sun’s upper limb is used, introducing a small additional discrepancy; and third, because Earth is not a perfect sphere and because of seasonal location on Earth relative to the equator, the exact length can vary slightly by latitude.
Despite these caveats, the general concept of an equinox is that day and night are approximately equal in length, with the caveats typically only causing small deviations from a perfect 12:12 balance.
Thus, the statement captures the core idea, but it is not strictly exact in all practical measurements due to atmospheric and observational definitions. The core misalignment in the option is the absolute phrasing of equal length everywhere, which ignores these small-but-real nuances.
