A Wonderleaf question
Why does it rain?
a real page from the book
Rain falls when water vapor cools inside clouds, gathers into droplets, and grows too heavy for air to keep carrying. The water began on the ground or in oceans, rose after warming, and then changed back into liquid high above us. When enough drops join, gravity pulls them down.
A cloud can look soft and still be busy inside. Tiny drops are bumping, joining, and gaining weight while winds move them around. The water landing on a coat today may once have been seawater, stream water, or part of another cloud long ago.

Watch steam from a warm cup meet a cool spoon, then notice the tiny drops that gather underneath.
