What is acid rain?
Is a mixture of wet and dry deposition, from the atmosphere containing higher amounts of nitric and sulphuric acids.
Wet deposition- This relies too acidic rain, fog and snow. If the acid chemicals in the air are blown into areas where the weather is wet, the acids can be in the form of rain, snow, fog, or mist. As this acidic water flows over and through the ground, it affects a variety of plants and animals.
Dry deposition-In areas where the weather is dry, the acid chemicals may become dust or smoke and fall to the ground through dry deposition, sticking to the ground, buildings, homes, cars, and trees. Dry deposited gases and particles can be washed from these surfaces by rainstorms, leading to increased runoff. This runoff water makes the resulting mixture more acidic. About half of the acidity in the atmosphere falls back to earth through dry deposition.

http://www.epa.gov/acidrain/what/index.html How acid rain is formed? The primary cause of acid rain is air pollution from burning fossil fuels. Fossil fuel use does not directly release acids into the atmosphere. Instead, it releases large amounts of acid precursors, primarily sulphur oxides (SOx) and nitrogen oxides (NOx). When exposed to the atmosphere, these react with water to form sulphuric acid and nitric acid. http://www.umac.org/ocp/HowisAcidRainFormed/info.html The range of PH in acid rain and how this is linked to…
