Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern...
Miina Härma Gymnasium Acid Rain Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because...

It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon The term "acid rain" was generated in 1972 Canadian Harold Harvey was among the first to research a "dead" lake Public awareness of acid rain in the U.S increased in the 1970s after the New York Times promulgated reports from the Hubbard Brook Experimental Forest in New...
Acid rain is rain or any other form of precipitation that is unusually acidic . It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid...
Acid rains This morning you contributed to atmosphere desolation H ow it is formed? Acid rain is formed by burning fossil fuels such as coal, natural gas, and oil. Gases of acid rain Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. Our health and acid rain Acid rain effects even our health. Breathing and lung problems in people (especially those with asthma) and have been linked to acid air pollution. Some things that you can do to make acid rain less of a problem are: Only run the dishwasher and washing machine with a full load. Turn off the lights in empty rooms or when you will be away from home....
As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible...

She fought for many issues to offer people better and more fair life. One of Thatcher's acts in her last half year in office was to put pressure on US President George H. W. Bush to deploy troops to the Middle East to drive Saddam Hussein's army out of Kuwait. At one point, Thatcher, became publicly concerned with environmental issues in the late 1980s. In 1988, she made a major speech communicating the problems of global warming, ozone depletion and acid rain . Margaret Hilda Thatcher began losing her popularity in 1989. Thatcher's political downfall was, according to witnesses such as Alan Clark, one of the most dramatic episodes in British political history. I think that Margaret Thatcher has affected Britain and eaven the whole world in many ways and all intelligent people knows something about that significant woman....
The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain , that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects. Like heavy traffic in the morning, while you are...
kohal. Happesademed mõjutavad ka järvi. FAKT: Happesademed on hävitanud maailmselt üle 1600 järve Järvedes, mis on happevihmade poolt saastatud, jäävad ellu vaid tugevaimad liigid. Kalad surevad, ja nii kaob lindude peamine toiduallikas. Samuti võivad linnu surra süües toksilisi kalu ja putukaid. Happevihmad võivad lausa tappa kalad isegi enne kui nad on sündinud. Acid rain hits the lakes mostly in the springtime, kui kalad munevad oma mune. Munad on kontaktis happega ja terve generatsioon võib surra. Kalad surevad tavaliselt siis kui järve happetase on kõrge; kui see on aga madalam siis kalad võivad jääda haigeks, või kaotada võime paljuneda. Kuidas happesademed mõjutavad arhitektuuri Happevihmad võivad hävitada arhitektuuri ja kunstiteoseid. Happeosakesed võivad maanduda majadele põhjustades korrosiooni...
Nuclear power today Nuclear power is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulphur and particulates, or greenhouse gases. The use of nuclear power in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain . Nuclear power has important implications for our national security. Inexpensive nuclear power, in combination with fuel cell technology, could significantly reduce our dependency on foreign oil. Nuclear power plants have experienced an admirable safety record. About 20% of electricity generated in the U.S. comes from nuclear power, and in the last forty years of this production, not one single fatality has occurred as a result of the operation of a civilian nuclear power plant in the...
Mis on happevihmad? Happesademed ehk happevihmad on mis tahes sademed (tavaliselt vihm), mille pH on võrreldes looduslike sademetega madalam (pH < 5).Sademete normaalne pH on reeglina umbes 5,5. 1.1 Hapestumine Termin hapestumine iseloomustab kogu probleemistikku, hõlmates seega ka happelise depositsiooni põhjustatud muutusi mullale, veele, materjalidele ja tervisele. 2. Kuidas tekivad happevihmad? Kivisöe, põlevkivi ja naftasaaduste põletamisel satuvad õhku väävli- ja lämmastikühendid. Vääveldioksiid, vääveltrioksiid ja lämmastikühendid reageerivad õhus vihmaveega ning moodustavad mitmeid happeid, mis langevad sademetena maapinnale. 3. Happeliste oksiidide reageerimine õhus veeauruga.(tulemuseks on happed, mis põhjustavad happevihmasid.) SO2+H2O=H2SO3 SO3+H2O=H2SO4 2 NO2+H2O=HNO3+HNO2 4. Happevihmade tekke põhjused. 1) Inimtegevus-kütuste põlemine 2) Loodus-põlengud -äike -vulkaanid 5. Hap...

On the other hand, there are those who believe that life in the future will not be so trouble-free. We will have used up the world's natural resources, therefore our planet will be on the verge of destruction. What is more, some fear that pollution will have increased due to problems such as deforestation and that acid rain will only have been made worse. They do not consider, however, that modern technology can solve environmental problems as well as less pressing ones. All in all, I feel that life in the future will definitely be better. We are all searching for ways to improve our lives and we can only look ahead in order to do this. (V. Evans Successful Writing)...
The authors acknowledge that many practical barriers would need to be overcome to reach this theoretical capacity. Advantages Wind energy is fueled by the wind, so it's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses. Wind energy is a domestic source of energy, produced in the United States. The nation's wind supply is abundant. Wind energy relies on the renewable power of the wind, which can't be used up. Wind is actually a form of solar energy; winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. Wind energy is one of the lowest-priced renewable energy technologies available today, costing...
The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets. Sunflower head displaying florets in spirals of 34 a...
It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well...
