I get lots of rain where I live, what exactly causes it?
1_Wizard
It is liquid water in the form of droplets. Usually happens when the droplets have condensed!

What does condensed mean?
1_Wizard
It means got smaller. After condensed, it becomes heavy enough to fall under gravity.

So it goes up as a gas, then condenses and becomes heavier.  Cool! What makes the water go up in the first place?
1_Wizard
Very cool! It is moisture moving along three-dimensional zones of temperature and moisture contrasts.

Whoa. I didn't know rain had to do with different dimensions.
1_Wizard
Yeah, it is pretty crazy. Rain is responsible for depositing most of the fresh water of the earth.
