Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Acid rain; Blood rain; Cold drop (Spanish: gota fría; archaic as a meteorological term), colloquially, any high impact rainfall event along the Mediterranean coast of Spain; Drought, a prolonged water supply shortage, often caused by persistent lack of, or much reduced, rainfall; Floods. Flash flood; Rainstorm
Carbon dioxide that dissolves in water to form carbonic acid is the most important source of protons, but organic acids are also important natural sources of acidity. [33] Acid hydrolysis from dissolved carbon dioxide is sometimes described as carbonation, and can result in weathering of the primary minerals to secondary carbonate minerals. [34]
Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface. [2] Similarly, virgae happen on gas giant planets such as Jupiter. [citation needed] In September 2008, NASA's Phoenix lander discovered a snow variety of virga falling from Martian clouds. [3]
The worst of the rain happened overnight Wednesday, and on Thursday morning, the city of Oakland Park found itself with extra water flooding city streets, swamping some cars and filling local ...
Extreme rain battered Beijing, Tianjin and the province of Hebei in the wake of Typhoon Doksuri in late July, causing widespread flooding and damage in a region the size of Britain. The storms ...
Acid rain-damaged forest in Europe's Black Triangle. Such an increase in sulfate aerosol emissions had a variety of effects. At the time, the most visible one was acid rain, caused by precipitation from clouds carrying high concentrations of sulfate aerosols in the troposphere. [25]
