Acid rain falls on a forest, damaging the leaves of the trees.

Definition

Noun: * Acid rain: Rain (or any other form of precipitation, such as snow or fog) that is unusually acidic. This acidity is caused by the chemical reaction of water in the atmosphere with certain industrial gas emissions, primarily sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), which form acids.
