| acid rain |
rain with an abnormally high acid content caused by burning of fossil fuels, which release sulfur and nitrogen oxides. In the presence of sunlight, these pollutants form sulfates and nitrates that create sulfuric and nitric acids when dissolved in water.

| acid rain |
Develops when sulphur oxides (SOx) and nitrogen oxides (NOx), released by the combustion of fossil fuels (particularly coal), combine with moisture in the atmosphere to form sulphurous, sulphuric, nitrous and nitric acids. Because SOx and NOx are gases and because the formation of acid rain takes time, acid rain damage often occurs far from the source of the problem.
