| acid rain |
Refers loosely to a mixture of wet and dry "deposition" (deposited material) from the atmosphere containing higher than "normal" amount of nitric and sulfuric acids. The precursors or chemical forerunners of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur and nitrogen oxides resulting from fossil fuel combustion.

| 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.
