acid rain
Other forms: acid rains
Use the noun acid rain when you're talking about polluted precipitation, or rain that's made extremely acidic by dirty practices like burning coal.
Environmental scientists use the term acid rain to describe a specific phenomenon, rain that has such a high percentage of acid that it isn't safe for trees or bodies of water. It's caused by the emission of certain chemicals when fossil fuels are burned. Many countries have pledged to lower their emissions and thereby reduce acid rain. The first use of acid rain was in 1859.
