What’s the acid rain?
Acid rain is a rain or any other form of precipitaton that is unusually acidic.
What causes acid rain?
Acid rain is caused by the burning of fossil fuels.
Burning oil, gas and coal in power statons releases
Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere.
These gases mix with water droplets in the atmosphere creatng weak solutons of nitric and sulphuric acids. When precipitaton occurs these solutons fall as acid rain.
History of acid rain
Though acidic rain was discovered in 1852, it was not untl the late 1960s that scientsts began Widely observing and studying the phenomenon. The term
"acid rain“ was coined in
1872 by Robert Angus Smith.
During the last decade, acid rain has been a major concern because it contnues to contaminate large areas of our planet.
Acid rain occurs in the areas of major industrial emissions of sulfur dioxide and oxides of nitrogen .
What problems are caused by acid rain?
Acid rain causes a range of problems.
Acid rain: increases the acidity levels of rivers, lakes and seas. This can kill aquatc life. Acid rain increases the acidity levels of soils. This can kill vegetaton has been found to destroy the roots and leaves of forests and can erode buildings and monuments. Areas threatened by acid rain
Acid rains occur in highly industrialized areas where emissions of SO2 and NOx are very large.
However, due to transport by wind, can affect areas located thousands of miles of issuers.
The most affected places are:
-Europe: The most threatened areas are northern and central Europe.
- North America: The highly urbanized and industrialized regions of eastern Canada and northern and eastern United States, are the most threatened.
- Asia: Acid rain is emerging as a major problem in the developing world, especially in parts of
Asia and the Pacific where
