Seasons
Due to the tilt of Earth's axis as it revolves around the Sun, the planet experiences four seasons: spring, summer, fall, and winter. Seasons a…
Seasons exist because Earth's axis is tilted at 23.5 degrees relative to its plane of orbit.
As Earth orbits the Sun, one hemisphere tilts toward the Sun, receiving direct sunlight, causing summer, while the other tilts away, creating winter.
A solstice is the event when the Sun appears at its highest or lowest point in the sky relative to Earth’s equator.
The summer solstice in the Northern Hemisphere occurs on June 21 or 22, when the Sun’s rays shine directly on the Tropic of Cancer, bringing longer days and warmer weather.
The winter solstice in the Northern Hemisphere occurs on December 21 or 22. On this day, the Sun’s rays hit the Tropic of Capricorn, causing shorter days and colder weather.
Halfway between solstices are the equinoxes, when the Sun shines directly over the equator, giving equal hours of day and night.
In the Northern Hemisphere, the autumnal equinox occurs on September 22 or 23, marking the start of fall, while the vernal equinox occurs around March 21 or 22, signaling spring.
