I love rain and the smell of water vapor.
The smell of water vapor?  Does that have a scent?
Yeah, even though water vapor is invisible doesn't mean you can't smell it.
I guess I can smell certain residual waters like tap waters with heavy minerals.  What's something interesting about water that most people don't know?
When moisture moves along the three dimensional zones this causes rain to fall.
What or where is this three dimensional zone?  Does that have something to do with the triple point of pressure, temperature, and something else?  My memory of physics class is fuzzy.
It's just upwards towards the clouds. If enough of it moves upwards the rain will fall from the clouds.
Oh okay,  Gotcha.  I'm very curious about acid rain.  What is acid rain and what causes it? It used to be talked about heavily, but recently not so much.
