Can You Really Balance an Egg During the Equinox?
The first day of spring and the vernal equinox is this week. The equinox will occur on Saturday, March 20th. The vernal equinox marks the start of spring, an autumnal equinox marks the start of fall. During the spring and fall equinox, the sun is directly over the Earth’s equator and day and night lengths are equal for most of the planet – 12 hours of light and 12 hours of darkness.
The earth rotates around the sun on a tilted axis, which doesn’t change. When the Northern Hemisphere is tilted toward the sun, it experiences warmer, longer days. When the Northern Hemisphere tilts toward the sun, the Southern Hemisphere is tilted away, experiencing colder and shorter days.
As the earth continues on its path around the sun, there are two points at which the sun hits the Earth perpendicular to the axis. When the earth is in this position, the sun is directly over the equator and there is an equinox. The earth then continues to tilt the opposite side of the sun and the seasons change to winter in the Northern Hemisphere and summer in the Southern Hemisphere.
