Varstu Keskkool 10. klass Elise Kasak Mangaan Referaat Juhendaja: Helen Oppar Varstu 2009 1. Nimetus ja avastamine Mangaan ja magneesium said oma nimetused sõnast magneesia. Kahe keemilise elemendi nimetuse tulenemine ühest ja samast sõnast seletub sellega, et pürolusiiti vastandati kaua aega valgele magneesiale ja nimetati mustaks magneesiaks. Pärast metalli saamist puhtal kujul nimetati mangaan ümber. Nimetuse aluseks oli kreekakeelne sõna manganese, mis tähendas puhastama (vihje selle kasutamisele minevikus klaasi puhastajana). Mõned uurijad arvavad, et elemendi nimetus tulenes ladinakeelsest sõnast magnes magniit, kuna pürolusiiti, millest toodetakse mangaani, peeti minevikus selle aine teisendiks, mida praegu nimetatakse magnet- rauamaagiks. (5) Rootsi keemik Karl Wilhelm Scheele tunnistas 1774. aastal esimesena mangaani elemendina. Samal aastal eraldas Ghan mangaani maakidest. (7) Pisiomelaan (mangaanimaak) (6) 2. Levik
Such fruits as apples and pears are grown in all the states. New South Wales and South Australia produce most of country's oranges. South Australia also produces grapes for use in making wine. Mining. Australia is rich in mineral resources. But roads and railways have to be constructed to the mining sites, so that the mining industry depends heavily on foreign capital. During the 1950's, geologists found huge deposits of coal and iron ore in Australia. Manganese, natural gas and petroleum were discovered in the 60's. Australia has got minerals like: copper, gold, silver, zinc, iron, nickel. Manufacturing. Australia imports more manufactured goods than it exports. The nation has to import many of its producer goods factory machinery, construction equipment and so on. Australia's iron and steel industry produces enough of the metals to meet the needs of other industries. The leading manufactured products are food, cars,

Agriculture is the major industry in Australia. People grow grain and bred sheep. The Australian wool industry is widely recognised as producing the finest quality Merino wool. Eastern Australia is the biggest farming region. Australia is rich in many minerals; mining has been an important branch of Australia's industry. Minerals are found and mined in most states, but Western Australia has become the most important region of mineral production. Gold, manganese ore, uranium and nickel ore are mined there. Australia is also rich in precious and semiprecious stones. Black opals and pink diamonds are though to be especially valuable. Australia is a very rich country because of its mineral sources. People: The earliest humans living in Australia are called Aborigines, and they are descended from among the earliest humans in the world. They are native people who came from Asia about 30 000 or 40 000 years ago
grows mainly there. Due to warm climate, bananas, peaches, grapefruits, olives, pineapples and sugar-canes are grown in Australia. Economy One of the most important branches in Australia's industry is (and has been) mining, because Australia is very rich in minerals. Minerals can be found in most states, so it is a vital part of Australia's economy. The leading mineral production area is Western Australia, where gold, uranium, nickel ore and manganese ore can be found. Australia is also rich in precious and semiprecious stones, like black opals and pink diamonds for example. It is said that mining produces 20% of Australia's export. Lead and zinc are also found in Australia in quite large amounts from Mount Isa and Broken Hill. Besides those two, copper, uranium, coal and oil are found in Australia. Most of the goods produced in Australia come from New South Wales. Iron, steel, power cables, jet aircrafts all come from there

where the nation's capital, Canberra lies. Western Australia. The capital is Perth. The largest state of Australia, this dry region is under the deserts and semideserts mostly. Bushland, so typical of this region, gives way to subtropical forests in the south west. In wetter parts of this region plains are used for breeding merino sheep. If possible, wheat, citruses and fruits are grown. This part of the country is extremely rich in minerals: lead, manganese, iron-ore, nickel, silver, gold, copper, bauxite and coal. Western Australia provides 75% of Australia's 240 tonnes of gold. Many immigrants live there because it was the last state to accept convicts. South Australia. The capital is Adelaide. Miles and miles of flat and treeless land. The average rainfall on plains is 10 inches a year and it all drains quickly underground, so there are no surface streams. The water lies hundreds and sometimes thousands of feet underground

engineer of the Port Authority of New York, one of the remarkable public works organizations of the USA, if not the world. Opening three weeks after the George Washington Bridge, then the longest suspension bridge in the world, this second record-breaking span was financed and built by the Port Authority simultaneously, the two projects forming one of the greatest public work endeavours since Roman times. The Bayonne Bridge connects Bayonne (New Jersey) and Staten Island (New York) with a manganese-steel parabolic two-hinged arch of 1675ft (511m) span and 266ft (81m) rise, the deck clearing high water by 150ft (46m). As in the Hell Gate, the arch's top chord acts as a stiffener, the bottom chord carrying the load. The Bayonne Bridge was designed to be 25ft (8m) longer than the nearly identical Sydney Harbour Bridge in Australia, started five years earlier. Bridges in areas other than Europe and the USA should be investigated, as the colonial empires of

The country is rich in mineral resources: iron ore, coal, manganese, natural gas (shale costly and dangerous to extract), oil, sulfur, graphite, titanium, magnesium, kaolin, nickel, mercury, timber and others. It's commonly known that Ukraine is politically divided between its Western and Eastern regions. Ukraine's geography and history have played an important role in the country's current political crisis. Western parts of the country at times belonged to Poland, Austro-
question and jeopardy if the present trend of consolidation of our conquerors continue. (There is no Black entity that is economically independent in any part of the world. Africa is the second largest continent in the world. It has been established that it was the cradle of humanity and civilisation. Africa possesses the largest percentage of the world’s natural resources – gold, diamonds, silver, uranium, plutonium, manganese, coal, oil. But unfortunately, Africa is today economically under occupation although I would have preferred to use the word military than occupation. The fact is that none of the natural resources Africa is blessed with under Africa control. We don’t even understand the value of the natural resources we possess; otherwise, we would know how to cultivate them. If we did, we would own the avenues through which these products are brought to be utilized in the world. The
