Question
Why is 21st March geographically important?
Answer
March 21 is geographically important because it marks the occurrence of two important astronomical events – the Vernal Equinox and the Autumnal Equinox, depending on the hemisphere.
- In the Northern Hemisphere, March 21 marks the Vernal Equinox, also known as the Spring Equinox. This is the moment when the Sun is directly above the equator and the length of day and night is almost equal. It also marks the beginning of the spring season in the Northern Hemisphere.
- In the Southern Hemisphere, March 21 marks the Autumnal Equinox. This is the moment when the Sun is directly above the equator and the length of day and night is almost equal. It also marks the beginning of the fall season in the Southern Hemisphere.
