Chemical processes by which acid precipitation is formed

Im lost and would be wish to be found. If you have a second i could use the help.

Acid precipitation forms by different processes. It depends on which acid is the end result. There are three common ones:

Carbonic Acid - created by carbon dioxide being absorbed into water droplets

Nitric Acid - nitrous oxide being absorbed by raindrops

Sulfuric Acid - sulfur dioxide being absorbed by raindrops

Here is a link that shows the actual chemical process:
