Even if your sky looks calm, there’s a storm somewhere. Earth produces countless electrical discharges at once—we just mistake our horizon for the whole world.
We picture sand, but deserts are defined by rainfall. Antarctica gets so little precipitation it’s technically a vast desert—its snow cover simply hides the fact.
In some coasts there’s water but almost no usable oxygen, forcing life to flee. Excess nutrients trigger algal blooms, then decay consumes oxygen and the area goes quiet.
While a mountain’s windward side gets soaked, the other side can dry out. Air rises, drops rain, then descends, warms, and loses moisture—creating a rain shadow.
The rocks at the bottom of the Grand Canyon are about half as old as Earth.
