The earliest humans knew that the sun’s path across the sky, the length of daylight, and the location of the sunrise and sunset all shifted in a regular way throughout the year.
They built monuments, such as Stonehenge, to follow the sun’s yearly progress.
Today, we know that the solstice is an astronomical event, caused by Earth’s tilt on its axis, and its motion in orbit around the sun.
Because Earth doesn’t orbit upright, but is instead tilted on its axis by 23-and-a-half degrees, Earth’s northern and southern hemispheres trade places in receiving the sun’s light and warmth most directly.
Summertime, And the livin' is easy Fish are jumpin' And the cotton is high Oh, Your daddy's rich And your mamma's good lookin' So hush little baby Don't you cry One of these mornings You're going to rise up singing Then you'll spread your wings And you'll take to the sky But until that morning There's a'nothing can harm you With your daddy and mammy standing by Summertime, And the livin' is easy Fish are jumpin' And the cotton is high Your daddy's rich And your mamma's good lookin' So hush little baby Don't yu cry
