White Cliffs, New South Wales
White Cliffs is a small town in outback New South Wales in Australia, in Central Darling Shire. White Cliffs is around 255 km northeast of Broken Hill, 93 km north of Wilcannia. At the , White Cliffs had a population of 156. The primary school opened in 1895, and has operated continuously since then. White Cliffs was one of the many places visited by Bill Bryson in research for the book ''Down Under''. History The town was established in the late 19th century when opal was discovered. Opal has been mined ever since. The first Australian opal was found 20 years before in Queensland in 1872, when a party of kangaroo hunters were operating in the White Cliffs area. One of them, who had left the party to track down a wounded kangaroo over some low stony hills, picked up a pretty stone which appealed to him. When taking back the stone, they suspected it could be opal which the local jeweller confirmed. He advised to get as much opal as possible since this could be more prof ...

Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Estimated resident population, 30 June 2017. Nicknames of the city include the 'Emerald City' and the 'Harbour City'. Aboriginal Australians have inhabited the Greater Sydney region for at least 30,000 years, and Aboriginal engravings and cultural sites are common throughout Greater Sydney. The traditional custodians of the land on which modern Sydney stands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Cliffs Opal Fields
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Evapotranspiration
Evapotranspiration (ET) is the combined processes by which water moves from the earth’s surface into the atmosphere. It covers both water evaporation (movement of water to the air directly from soil, canopies, and water bodies) and transpiration (movement of water from the soil, through roots and bodies of vegetation, on leaves and then into the air). Evapotranspiration is an important part of the local water cycle and climate, as well as measurement of it plays a key role in agricultural irrigation and water resource management. Definition Evapotranspiration is a combination of evaporation and transpiration, measured in order to better understand crop water requirements, irrigation scheduling, and watershed management. The two key components of evapotranspiration are: * Evaporation: the movement of water directly to the air from sources such as the soil and water bodies. It can be affected by factors including heat, humidity, and wind speed. * Transpiration: the move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

White Cliffs Solar Power Station, New South Wales
White Cliffs Solar Power Station was Australia's first solar power station. It is located at White Cliffs, New South Wales, which was chosen as it has the highest insolation in New South Wales, and in 1981 when the station was constructed had no grid connection. Constructed by a team from Australian National University, the station consisted of fourteen five-metre parabolic dishes, each covered by more than 2000 mirrors and mounted on a heliostatic mounting. The dishes each focussed the sun's rays on a collector, where water was boiled. The resulting steam drove a three-cylinder Uniflow steam engine, made by modifying a Lister diesel engine, delivering up to 25kWe. Batteries were used to provide 24-hour power to selected buildings in the township, and an existing diesel generator retained to provide battery charging when either low insolation or strong winds prevented use of the solar station for extended periods. In 1996, following grid connection of the township, the stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill O'Reilly (cricketer)
William Joseph O'Reilly OBE (20 December 19056 October 1992) was an Australian cricketer, rated as one of the greatest bowlers in the history of the game. Following his retirement from playing, he became a well-respected cricket writer and broadcaster. O'Reilly was one of the best spin bowlers ever to play cricket. He delivered the ball from a two-fingered grip at close to medium pace with great accuracy, and could produce leg breaks, googlies, and top spinners, with no discernible change in his action.Wisden (1935), pp. 284–286. A tall man for a spinner (around 188 cm, 6 ft 2 in), he whirled his arms to an unusual extent and had a low point of delivery that meant it was very difficult for the batsman to read the flight of the ball out of his hand. When O'Reilly died, Sir Donald Bradman said that he was the greatest bowler he had ever faced or watched. In 1935, ''Wisden'' wrote of him: "O'Reilly was one of the best examples in modern cricket of what could be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kangaroo
Kangaroos are four marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms "wallaroo" and "wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size. There are also the tree-kangaroos, another type of macropod, which inhabit the tropical ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Down Under (book)
''Down Under'' is the British title of a 2000 travelogue book about Australia written by best-selling travel writer Bill Bryson. In the United States and Canada it was published titled ''In a Sunburned Country'', a title taken from the famous Australian poem, "My Country". It was also published as part of ''Walk About'', which included ''Down Under'' and another of Bryson's books, '' A Walk in the Woods: Rediscovering America on the Appalachian Trail'', in one volume. Summary Bill Bryson describes his travels by railway and car throughout Australia, his conversations with people in all walks of life about the history, geography, unusual plants and animals of the country, and his wry impressions of the life, culture and amenities (or lack thereof) in each locality. In a style similar to his book ''A Walk in the Woods'', or William Least Heat-Moon's '' Blue Highways'', Bryson's research enabled him to include many stories about Australia's 19th-century explorers and settlers who s ...

Broken Hill, New South Wales
Broken Hill is an inland mining city in the far west of outback New South Wales, Australia. It is near the border with South Australia on the crossing of the Barrier Highway (A32) and the Silver City Highway (B79), in the Barrier Range. It is 315m above sea level, with a hot desert climate, and an average rainfall of 235mm. The closest major city is Adelaide, the capital of South Australia, which is more than 500km to the southwest and linked via route A32. The town is prominent in Australia's mining, industrial relations and economic history after the discovery of silver ore led to the opening of various mines, thus establishing Broken Hill's recognition as a prosperous mining town well into the 1990s. Despite experiencing a slowing economic situation into the late 1990s and 2000s, Broken Hill itself was listed on the National Heritage List in 2015 and remains Australia's longest running mining town. Broken Hill, historically considered one of Australia's boomtowns, has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
