Acid rain

Gases dissolve in atmosphere

Carbon dioxide, sulfer dioxide, hydrogen chloride all creat acidic solutions

Carbonic acid= CO2

Sulfur dioxide= acid rain

Acid rain can kill forests, and pollute water.

Ocean acidification

Normal ocean PH is 8.1-8.4

The oceans PH has decreased 0.1 which is 25%

Lower ocean ph means saw animals with shells will not be able to make shells.
