acid rain1
Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Primarily caused by air pollution, acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and in lakes and streams. This form of air pollution is currently a subject of great controversy because of its worldwide environmental damages. For the last ten years, this problem has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe.Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil. Power plants use that coal and oil to produce the electricity for our homes and to run our electric appliances. We also burn natural gas, coal, and oil to heat our homes. The smoke and fumes from burning fossil fuels rise into the atmosphere and combine with the moisture in the air to form acid rain. The main chemicals in air pollution that creates acid rain are sulfur dioxide and nitrogen oxides. Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild
The other chemical that is also chiefly responsible for the make-up of acid rain is nitrogen oxide. That makes matters worse because due to the increase in the death of fish their decomposition takes up even more oxygen. It can harm us through the atmosphere or through the soil from which our food is grown. Clean air also contains naturally occurring gases such as carbon dioxide. In the atmosphere it reacts with water to form nitric or nitrous acid. Not all species can tolerate the same amount of acid. Spring is a vulnerable time for many species since this is the time for reproduction. This causes the release of sulfur dioxide. Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. Fertilizer helps stimulate the growth of algae because of the amount of nitrogen in it. The Roman monuments cost the Romans about $200 million for acid rain repairs. There may be no clear answer to the acid rain problem. Automobiles are the main source of nitrogen oxide emissions, and utility factories are the main source for sulfur dioxide emissions. The interaction between the water droplets and the carbon dioxide in the atmosphere, and also from chlorine, which comes from the salt in the sea, gives rain an average pH of about 5. Marble, limestone, and sandstone can easily be dissolved by acid rain.
