Adelaide City Centre
Adelaide city centre (Kaurna: Tarndanya) is the inner city locality of Greater Adelaide, the capital city of South Australia. It is known by locals simply as "the City" or "Town" to distinguish it from Greater Adelaide and from the City of Adelaide local government area (which also includes North Adelaide and from the Park Lands around the whole city centre). The population was 15,115 in the . Adelaide city centre was planned in 1837 on a greenfield site following a grid layout, with streets running at right angles to each other. It covers an area of and is surrounded by of park lands.The area of the park lands quoted is based, in the absence of an official boundary between the City and North Adelaide, on an east–west line past the front entrance of Adelaide Oval. Within the city are five parks: Victoria Square in the exact centre and four other, smaller parks. Names for elements of the city centre are as follows: *The "city square mile" (in reality 1.67 square miles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% ...

Overgrazed
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savannas, ...

Electoral District Of Giles
Giles is a single-member electoral district for the South Australian House of Assembly. Named after explorer Ernest Giles, it is the largest electorate in the state by area, covering of South Australian outback. Its main population centre is the industrial city of Whyalla on the far south-east border of the seat which represents half of the electorate's voters. The electorate covers significant areas of pastoral leases and Pitjantjatjara Aboriginal land stretching to the Western Australian and Northern Territory borders, taking in the remote towns of Andamooka, Coober Pedy, Ernabella, Fregon, Marla, Mimili, Mintabie, Oodnadatta, and Tarcoola. Giles also has a far north mobile booth. Giles was created at the 1991 electoral redistribution to replace the abolished electoral district of Whyalla. It covered an area that had traditionally been one of the few country areas where Labor consistently did well. Support for the party was particularly strong in the city of Whyalla, whic ...

Division Of Grey
The Division of Grey is an Australian electoral division in South Australia. The division was one of the seven established when the former Division of South Australia was redistributed on 2 October 1903 and is named for Sir George Grey, who was Governor of South Australia from 1841 to 1845 (and later Prime Minister of New Zealand). Geography Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned. The division covers the vast northern outback of South Australia. Highlighting South Australia's status as the most centralised state in Australia, Grey spans , over 92 percent of the state. The borders of the electorate include Western Australi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Artesian Basin
The Great Artesian Basin (GAB), located in Australia, is the largest and deepest artesian basin in the world, stretching over , with measured water temperatures ranging from . The basin provides the only source of fresh water through much of inland Australia. The Basin underlies 22% of the continent, including the states and territories of Queensland (most of), the Northern Territory (the south-east corner of), South Australia (the north-east part of), and New South Wales (northern part of). The basin is deep in places and is estimated to contain of groundwater.

Kokatha
The Kokatha, also known as the Kokatha Mula, are an Aboriginal Australian people of the state of South Australia. They speak the Kokatha language, close to or a dialect of the Western Desert language. Country Traditional Kokatha lands extend over some according to the estimation of Norman Tindale, stretching over some of the harshest, waterless land on the Australian continent. They include Tarcoola, Kingoonyah, Pimba and the McDouall Peak as well as modern townships of Roxby Downs and Woomera. The lands extend west as far as Ooldea and the Ooldea Range while the northern frontier runs up to the Stuart Range and Lake Phillipson. Their boundary with Barngarla lands is marked by an ecological transition from their plateau to the lower hilly acacia scrubland and salt lake zones running south to the coast. The tribes bordering on Kokatha lands were, running north clockwise, the Pitjantjara, the Yankuntjatjarra, the Antakirinja, the Arabana and Kuyani to their east, the Barngarla ...

Woomera, South Australia
Woomera, unofficially Woomera village, refers to the domestic area of RAAF Base Woomera. Woomera village has always been a Defence-owned and operated facility. The village is located on the traditional lands of the Kokatha people in the Far North region of South Australia, but is on Commonwealth-owned land and within the area designated as the 'Woomera Prohibited Area' (WPA). The village is approximately north of Adelaide. In common usage, "Woomera" refers to the wider RAAF Woomera Range Complex (WRC), a large Australian Defence Force aerospace and systems testing range (the 'Woomera Test Range' (WTR)) covering an area of approximately and is operated by the Royal Australian Air Force. Woomera 'village' is part of RAAF Base Woomera which, along with the ''Woomera Test Range'' (WTR), forms the larger entity known as the Woomera Range Complex (WRC), promulgated by Chief of Air Force (CAF) in June 2014.

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Opal
Opal is a hydrated amorphous form of silica (SiO2·''n''H2O); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Due to its amorphous property, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals. It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. The name ''opal'' is believed to be derived from the Sanskrit word (), which means 'jewel', and later the Greek derivative (), which means 'to see a change in color'. There are two broad classes of opal: precious and common. Precious opal displays play-of-color ( iridescence); common opal does not. Play-of-color is defined as "a pseudo chromatic optical effect resulting in flashes of colored light from certain minerals, as they are turned in white light." The internal structure of precious opal causes it to di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
