Acid rain‚ or more accurately acid precipitation‚ is the term used for describing rainfall with a pH level lower than 5.6. This type of pollution is a matter of great debate currently due to the potential of its causing environmental damages all across the world. For the last decade or so acid rain has caused destruction to hundreds of lakes and streams in many parts of the world‚ including the US‚ Canada‚ and Europe. Acid rain forms due to the oxides of sulfite and nitrogen combining with the moisture

What it is: • the deposition of acidic components in rain‚ snow‚ dew‚ or dry particles. • more accurate term is "acid precipitation." • defined as any type of precipitation with a pH that is unusually low The Causes: • occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere‚ undergo chemical transformations and are absorbed by water droplets in clouds • then fall to earth as rain‚ snow‚ mist‚ dry dust‚ hail‚ or sleet. • Dissolved carbon dioxide dissociates to form weak

Acid rain is a rain or any other form of precipitation that is unusually acidic‚ i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals‚ and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive
