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. [1] [2] The more acidic the acid rain is, the lower its pH is. [2] Acid rain can have harmful effects on plants, aquatic animals, and infrastructure.
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.

Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...
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.
