Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries, coal burning factories, power plants and automobile engines are the main sources of sulfur dioxide and nitrogen oxide which cases acid rain.
Volcanoes and forest fires also causes sulfur dioxide and nitrogen oxide. Some of the many problems that come from acid rain is the killing of of many plants and underwater life in thousands of lakes and streams around the world. It strips forest soils of nutrients and damages farm crops. Acid rain can also corrode stone buildings, bridges, and priceless monuments.
Acid rain can also be harmful to humans because acid rain kills the crops and fish we eat, ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a polluted area could carry pollution to another area and the acid rain could fall there. The regions effected more by acid rain is large parts of eastern North America, Scandinavia, and central Europe. In alot of places acid rain isn't a problem because some soils can neutralize the acid and it doesn't effect the crops. Areas more sensitive to acid rain is in the western United States most of Washington all of Oregon, section of California and most of Idaho. Maine, New Hampshire, Vermont and a large section of north east Canada.
The soil in these places can not neutralize acid rain deposits, then the nutrients are stripped which means the crops in those places may not survive. The Black forest is a mountainous region in Baden-Wurttemberg, in southwestern Germany. The valleys are fertile and make good pasture land as well as providing good soil vineyards. No forest region is showing serious effects of acid rain. Many trees are dying, the forest lost masses of needles, leaving them with sparse, stuffing crowns. Their major industries are Lumbering wood, manufacturing toys and cuckoo clocks.
Winter sports and mineral springs attract tourists. Acid rain can damage and ruin soils by stripping the soils nutrients. But some soils can neutralize and weaken acid deposits that fall from the sky. These soils are called alkaline soil, also called a base. In 1838 the German chemist Justus von Liebig offered the first really useful definition of an acid, namely, a compound containing hydrogen that can react with a metal to produce hydrogen gas. Soil is formed when rocks are broken up by the weather and erosion and mixed with organic matter from plants and animals.
The term soil generally refers to the loose surface of the Earth, made from solid rock. To the farmer, soil is the natural medium for growth of all land plants. The rocks that make up soil could be acid, neutral, or alkaline, another name for a base. Limestone and chalk are rocks that are formed from tiny shells that are rich in calcium. Alkaline is made up of calcium. When acid rain falls on alkaline soil the calcium makes the acid become weaker or neutralize.
Farmers put lime (a very strong alkaline substance) and special fertilizers in there soil neutralize the acid in the soil on a regular daily basis. In general, soil structure is classified as sandy, clay, or loam, although most garden soils are mixtures of the three in varying proportions. A sandy soil is very loose and will not hold water. A clay soil is dense and heavy, sticky when wet, and almost brickyard when dry. Loam is a mixture of sand and clay soils, but it also contains large quantities of humus, or decayed organic material, which loosens and aerates clay soil and binds sandy soil particles together.
In addition, humus supplies plant nutrients. Then, soil structure can be improved by digging in compost, manure, peat moss, and other organic matter. Parts of western United States, Minneapolis, northeastern North America and east and north Canada are places in North America where the is more sensitive to acid deposits then any other places. Many factors, including the soil chemistry and the type of rock determine the enviroment's ability to neutralize the acid deposits from the rain.
Soils naturally contain small amounts of poisonous minerals such as mercury, aluminum, and cadmium. Normally, these minerals do not cause serious problems, but as the acidity of the soil increases, chemical reactions allow the minerals to be absorbed by the plants. The plants are damaged and any animals that eat the plants will about the poisons, which will remain in the animals body and can hurt them or even kill them. The harmful minerals can also leach out of the soil into streams and lakes where they can kill fish and other types of living creatures. The problem gets even bigger and bigger when pollution dumps more minerals in the soil. For example, in some parts of Poland vegetable crops have been found to contain ten times more lead than is considered safe.
Some plants need and require soil, and the farmers do not want lime to be put in there soil. If acid requiring plants, such as some types of shirts, are put in alkaline soil those plants are very likely to start to look yellow and very sickly very soon. Even if the water you give to the plants came from limestone strata it could neutralize the soil. Continued use of some types of fertilizer may be cause the loss of acidity, too. If the soil does not have enough acid in it, it may be made more acidic by the application of alum, sulfur, or by adding gypsum to the soil. To add more acid to the soil you can also lift the plants and replacing the whole bed to a depth of nine inches with acid soil.
It is not easy to make neutral soils acid. Sulfur is the most commonly used to increase the soils acidity, but it acts very slowly. So acid rain is good for some plants in some places with alkaline soil because some of the plants want acid. Some acid requiring plants are several popular shirts, including azalea, camelia, gardenias, blueberries, and rhododendron. Soils can be acid, alkaline, or neutral.
The amounts of alkaline and acid in the soil influence the biological and chemical processes that take place in the soil. Highly alkaline or acid soils can harm many plants. Neutral soils can support most of the processes. Florida's sandy soils are naturally acidic, but the soil is easily changed from acid to neutral or even a base (base is alkaline soil) by the small amounts of lime and calcium that come from tiny shells often found in the Florida's sandy beaches.
When acid rain falls from the sky it gets into the soil. The plants only have time to absorb and store the water when the soil is wet. Then the leftover water in the soil evaporates back into the sky where it becomes water vapor, forms into clouds, and gets ready to rain again. It is the same thing with acid rain. The acid doesn't stay in the soil. The acid evaporates back into the sky.
Pedologists are scientists who study the soil. They classify the soils according to the characteristics of a polyhedron. There are ten groups of soils, they are Alfisols, Aridisols, Entisols, Histosols, Inceptisols, Mollisols, Oxisols, Spodosols, Ultisols, and Vertisols. Alfisols develop under forests and grasslands in humid climates.
Aridisols occur in dry regions and contain small amounts of organic matter. Entisols show little development. Histosols are organic soils. They form water situated environments, including swamps and bogs.
Inceptisols are only slightly developed. Mollisols develop in price regions. They have thick organically rich topsoil's. Oxisols are the most chemically weathered soils. They have a reddish color and occur in the tropical parts of the world. Spodosols contains iron, aluminum, and organic matter in there B horizons.
They form in humid climates. They are moist, well-developed, acid soils. Vertisols form in sub humid and arid warm climates. They make wide, deep cracks during the dry season. Other soil groups are the tundra, pool, chernozem. Tundra soils have dark brown surfaces and darker subsoil's than in arctic regions that are underlain by permafrost.
The soils can be farmed if they are well drained and permafrost is absent or deep-lying. Pool soils are moderately to strongly leached soils in forests and in humid regions. They are not naturally very productive for agriculture. Chernozem soils (from Russian for 'black earth') have a dark surface layer underlain by more lightly colored soil. They typically develop under grasses while the temperate is cool. Sub humid climates are highly productive, although they require fertilizers after a long use.
