what makes acid rain?

Answer 1

polution

Answer 2

Acid rain (or more accurately acid precipitation)[1] occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain, snow, or sleet. This can increase the acidity of the soil, and affect the chemical balance of lakes and streams.[2] The term "acid rain" is sometimes used more generally to include all forms of acid deposition - both wet deposition, where acidic gases and particles are removed by rain or other precipitation, and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation.[3]

Acid rain is defined as any type of precipitation with a pH that is unusually low.[4] Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2.[5] Therefore a pH of <5.6 has sometimes been used as a definition of acid rain.[6] However, natural sources of acidity mean that in remote areas, rain has a pH which is between 4.5 and 5.6 with an average value of 5.0 and so rain with a pH <5 is a more appropriate definition.[7]

The US EPA says, "Acid rain is a serious environmental problem that affects large parts of the US and Canada" [8] Acid rain accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidification of rivers, streams, and forest damage at high elevations.

Answer 3

sulfer (or sulpher) dioxide in the rain, making it acidic (producing sulphuric acid, carbon dioxide also is mildly acidic when disolved in water) ; sulpher dioxide is produced from car exhausts, burning low qualtiy coal and volcanic events (the latter is less commom) - carbon dioxide from much the same

to combat acid rain authories spray lime over water and trees to react with the acid (sulphuric acid) and neutralise it

wikipedia has a nice little bit about sulpher/sulfer's enviromental damage:
"The burning of coal and petroleum by industry and power plants liberates huge amounts of sulfur dioxide (SO2) which reacts with atmospheric water and oxygen to produce sulfuric acid. This sulfuric acid is a component of acid rain, which lowers the pH of soil and freshwater bodies, resulting in substantial damage to the natural environment and chemical weathering of statues and architecture. Fuel standards increasingly require sulfur to be extracted from fossil fuels to prevent the formation of acid rain. This extracted sulfur is then refined and represents a large portion of sulfur production."

hope this helps

Answer 4

Well I remember the lyrics by Rush (tm) that said "There's no swimming in the heavy waters, or singing in the acid rain."
If you think Rush rocks than someone should at least give this one a thumbs up, no?

Answer 5

China

Answer 6

Simply put, its because of heavy air pollution.

Answer 7

acid. water. clouds.
