You may know that the summer solstice and spring equinox signal the changing seasons of the world, but do you remember which one? Are they different names for the same thing? Solstices and equinoxes are actually opposites.
This means that different parts of the world receive more or less sunlight at different times of the year. If the world were not tilted, the sun would be directly above the equator, the light coming to the center would be constant, and there would be no seasons. You should also mark the equinoxes or solstices. . On this day, the sun’s path across the sky is as far north or south as it is from the equator.
The winter solstice is the shortest day of the year in the hemisphere, while the summer solstice is the longest day of the year. In the Northern Hemisphere, the June solstice marks the beginning of summer: when the North Pole is closest to the sun, and the sun’s rays shine directly over the Tropic of Cancer.
December marks the beginning of winter: when the South Pole is closest to the sun, and the sun’s rays shine directly over the head of the Tropic of Capricorn. (The seasons change in the Southern Hemisphere.)
The equinoxes occur in March (around March 21) and September (around September 23). On this day, the sun is directly above the equator, and day and night are of equal length. The Earth orbits the sun; Vernal Equinox (around March 21):
Day and night are of equal length, marking the beginning of spring
Summer Solstice (June 20 or 21): Long days for most of the year, marking the beginning of summer
Autumn Equinox (around September 23): Day and night are of equal length, marking the beginning of autumn.
Winter Solstice (December 21 or 22): The shortest day of the year, marking the beginning of winter.
