The Science Behind the Spring Equinox
Understanding Equinoxes and Solstices
An equinox occurs twice a year, around March 20-21 and September 22-23, when the sun is positioned directly above the Earth's equator. During these times, both hemispheres receive nearly equal amounts of sunlight, resulting in approximately equal day and night lengths. In contrast, solstices mark the longest and shortest days of the year, occurring around June 21 and December 21.
Why Does the Spring Equinox Occur?
The spring equinox occurs due to the tilt of the Earth's axis and its orbit around the sun. As the Earth rotates, its axis remains tilted at an angle of about 23.5 degrees. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.
- March Equinox: Marks the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
- September Equinox: Marks the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
