What
causes rain?
When clouds develop or rain occurs, something is making the air rise. Several things can make this happen. Mountains, low-pressure areas, cold fronts, and even the jet stream.
How big are raindrops?
Raindrops are much smaller than we think! They are actually smaller than a centimeter. Raindrops range from 1/100 inch to 1/4 inch in diameter.

Raindrops are much smaller than we think! They are actually smaller than a centimeter. Raindrops range from 1/100 inch to 1/4 inch in diameter.
Not including
wind-driven rain, raindrops fall between 7 and 18 miles per hour (3 and 8
meters per second) in still air. The range in speed depends on the the size of
the raindrop. Air friction breaks up raindrops when they exceed 18 miles per
hour.
