The spring equinox, which occurs around March 21, is the event when day and night are approximately equal in length, lasting about 12 hours each. This balance occurs because the Sun is positioned directly over the equator. The same phenomenon occurs during the autumn equinox around September 23. These equinoxes mark the transitions between the seasons and are significant in many cultures.

During which event do day and night last approximately 12 hours each?a...
Understanding the Equinoxes
The equinoxes are significant astronomical events that occur twice a year, marking the points when the sun crosses the celestial equator. During these times, day and night are approximately equal in length.
Key Events of the Equinoxes
- Autumn Equinox: Occurs around September 22-23 in the Northern Hemisphere. Day and night are nearly equal.
- Spring Equinox: Occurs around March 20-21 in the Northern Hemisphere. Similarly, day and night last about 12 hours each.
Why the Spring Equinox is the Correct Answer
- Equal Day and Night: During both the autumn and spring equinoxes, the tilt of the Earth's axis is such that sunlight is distributed evenly across the globe. This results in nearly equal lengths of day and night.
- Timing: The spring equinox marks the transition from winter to summer. As the sun rises higher in the sky, days become longer following this event.
- Global Phenomenon: The phenomenon of equal day and night during the equinoxes is experienced worldwide, making it a unique and significant event in the calendar year.
Conclusion
In conclusion, both the autumn and spring equinoxes feature approximately 12 hours of day and night. However, the question specifically asks for the event that occurs in the spring, making option 'D' (Spring Equinox) the correct choice.
