INDIAN GEOGRAPHY

Detailed explanation-1: -On 21st March and September 23rd, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun; so, the whole earth experiences equal days and equal nights. This is called an equinox.

Detailed explanation-2: -The event, known as equinox, is eagerly awaited by space enthusiasts as it takes place only twice a year, on March 21 and September 23. On equinox, the sun moves across the celestial equator, which lies directly above the Earth’s equator.

Detailed explanation-3: -The variance in the length of day at the Equator between the Equinox and the Solstice is very slight and hence the equator gets basically 12 hrs of day and 12 hrs of night.

Detailed explanation-4: -Because the equator is halfway between the North and South poles, the days there are always 12 hours of daytime and 12 hours of nighttime. There is very little difference between the seasons. In the Southern hemisphere the seasons are at opposite times to the Northern hemisphere.
