During the spring equinox, locations in the Southern Hemisphere will

Question

BlackTom AI · Accepted Answer

When considering the spring equinox in the Southern Hemisphere, the key idea is that the Sun crosses the celestial equator, resulting in nearly equal day and night lengths.
Option 1: 'have 12 hours of darkness and 12 hours of daylight' correctly reflects the equal duration of day and night that occurs on equinoxes, including in the Southern Hemisphere.
Option 2: 'have daylight length greatest at the Equator' is misleading; daylight length does not peak at the Equator during the equinox; day length is about equal everywhere, and the equator does not have the longest daylight on an equinox.
Option 3: 'have more hours of daylight than darkness' would imply a solstice-like condition rather than an equinox; on an equinox, daytime and nighttime are essentially equal, not longer daylight.
Option 4: 'have more hours of darkness than of daylight' is the opposite of the equinox condition and would occur during the winter solstice in the respective hemisphere, not during the spring equinox.
Overall, the defining feature of an equinox is the near 12–hour split between day and night, which is correctly captured by option 1.
