The term "acid rain" specifically refers to precipitation that has a higher than normal level of acidity, typically caused by pollutants in the atmosphere. These pollutants, such as sulfur dioxide and nitrogen oxides, can be released from various sources, including the burning of fossil fuels, industrial emissions, and vehicle exhaust. When these chemicals react with water vapor in the atmosphere, they form sulfuric and nitric acids, which then fall to the ground as acid rain.

Understanding the implications of acid rain is crucial as it can have harmful effects on the environment, including soil degradation, water body acidification, and damage to flora and fauna. This distinct definition and the processes involved in its formation set "acid rain" apart from other terms that might suggest lowered quality but do not imply the specific chemical changes associated with high acidity.
