Question

what is an
equinox ? Explain​

Answer 1

Answer:

An equinox occurs when the position of the sun is exactly over the equator. When this happens, the hours of daylight and the hours of darkness are about equal almost everywhere on Earth. After the autumnal equinox, the days become shorter and the nights become longer.

This phenomenon is called an equinox, which comes from the Latin words "aequus" (equal) and "nox" (night).

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.
