Equinox means “equal night.”
Because the sun is positioned over the equator,
day and night are about equal in length all over the world during the equinoxes.
“Thanks to the 23.4 degree tilt of the Earth’s axis, we have days of different lengths and changes in the seasons. We receive the sun’s rays most directly in the summer. In the winter, when we are tilted away from the Sun, the rays pass through the atmosphere at a greater slant, bringing lower temperatures. If the Earth rotated on an axis perpendicular to the plane of the Earth’s orbit around the Sun, there would be no variation in day lengths or temperatures throughout the year, and we would not have seasons. ” (Source: Infoplease)
Trivia: How many hours of sunlight do we have on the longest day of the year (Summer Solstice) and how many hours of sunlight do we have on the shortest day (Winter Solstice).
