Geography Of Sydney
The geography of Sydney is characterised by its coastal location on a basin bordered by the Pacific Ocean to the east, the Blue Mountains to the west, the Hawkesbury River to the north and the Woronora Plateau to the south. Sydney lies on a submergent coastline on the east coast of New South Wales, where the ocean level has risen to flood deep river valleys (rias) carved in the Sydney sandstone. Port Jackson, better known as Sydney Harbour, is one such ria. The Sydney area lies on Triassic shales and sandstones. The region mostly consists of low rolling hills and wide valleys in a rain shadow area that is shielded by the Great Dividing Range. Sydney sprawls over two major regions: the Cumberland Plain, a relatively flat region lying to the west of Sydney Harbour, and the Hornsby Plateau, a plateau north of the Harbour rising to 200 metres and dissected by steep valleys. Sydney's native plant species are predominantly eucalyptus trees, and its soils are usually red and yellow i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornsby Plateau
The Hornsby Plateau is a dissected sandstone plateau lying to the north of Sydney Harbour that rises 200 metres. The plateau is a part of the larger Sydney Basin structure. Geography The North Shore and the Berowra Valley National Park are located on the Hornsby Plateau. It is separated from the Blue Mountains Plateau by the passage of the Colo River. The plateau rises from the Cumberland Plain in the south along a warp line increasing from the proximity of Cattai to Botany Bay. The plateau's elevation ranges between 200-220 metres, with gullies that fall 80-100 metres deep along drainage lines. Steep slopes with drastic ascension of over 100 metres are present. The soil type is generally lithosols, which has low fertility and is normally less than 500 mm deep. Geology Rock deposits in the Sydney area were tertiary freshwater sediments, which were a rough gravelly layer up to 8 metres thick located beneath silt and sand at a mean depth of 6 metres. As time went by, weathering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Beach, New South Wales
Palm Beach is a suburb in the Northern Beaches region of Sydney, in the state of New South Wales, Australia. Palm Beach is located north of the Sydney central business district, in the local government area of Northern Beaches Council.

Australian Bureau Of Statistics
The Australian Bureau of Statistics (ABS) is the independent statutory agency of the Australian Government responsible for statistical collection and analysis and for giving evidence-based advice to federal, state and territory governments. The ABS collects and analyses statistics on economic, population, environmental and social issues, publishing many on their website. The ABS also operates the national Census of Population and Housing that occurs every five years. History In 1901, statistics were collected by each state for their individual use. While attempts were made to coordinate collections through an annual Conference of Statisticians, it was quickly realized that a National Statistical Office would be required to develop nationally comparable statistics. The Commonwealth Bureau of Census and Statistics (CBCS) was established under the Census and Statistics Act in 1905. Sir George Knibbs was appointed as the first Commonwealth Statistician. Initially, the bureau w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be genera ...

Sydney Water
Sydney Water, formally, Sydney Water Corporation, is a New South Wales Government owned statutory corporation that provides potable drinking water, wastewater and some stormwater services to Greater Metropolitan Sydney, the Illawarra and the Blue Mountains regions, in the Australian state of New South Wales. History The origins of Sydney Water go back to 26 March 1888 when the was enacted and repealed certain sections of the relating to water supply and sewerage, thereby transferring the property, powers and obligations from the Municipal Council to the Board of Water Supply and Sewerage. Name changes The forebears of Sydney Water include: * Board of Water Supply and Sewerage (18881892) * Metropolitan Board of Water Supply and Sewerage (18921925) * Metropolitan Water Sewerage and Drainage Board (19251987) * Water Board (19871994) which had also been the colloquial name for the organisation for much of its history in the 20th century, and persists among longer term employees ...

Parramatta River
The Parramatta River is an intermediate tide-dominated, drowned valley estuary located in Sydney, New South Wales, Australia. With an average depth of , the Parramatta River is the main tributary of Sydney Harbour, a branch of Port Jackson. Secondary tributaries include the smaller Lane Cove and Duck rivers. Formed by the confluence of Toongabbie Creek and Darling Mills Creek at North Parramatta, the river flows in an easterly direction to a line between Yurulbin in Birchgrove and Manns Point in Greenwich. Here it flows into Port Jackson, about from the Tasman Sea. The total catchment area of the river is approximately and is tidal to Charles Street Weir in Parramatta, approximately from the Sydney Heads. The land adjacent to the Parramatta River was occupied for many thousands of years by Aboriginal peoples of the Wallumettagal nations and the Wangal, Toongagal (or Tugagal), Burramattagal, and Wategora clans of the Darug people. They used the river as an important source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepean River
Nepean River (Darug: Yandhai), is a major perennial river, located in the south-west and west of Sydney, New South Wales, Australia. The Nepean River and its associated mouth, the Hawkesbury River, almost encircles the metropolitan region of Sydney. The headwaters of the Nepean River rise near Robertson, about south of Sydney and about from the Tasman Sea. The river flows north in an unpopulated water catchment area into Nepean Reservoir, which supplies potable water for Sydney. North of the dam, the river forms the western edge of Sydney, flowing past the town of Camden and the city of Penrith, south of which flowing through the Nepean Gorge. Near Wallacia it is joined by the dammed Warragamba River; and north of Penrith, near Yarramundi, at its confluence with the Grose River, the Nepean becomes the Hawkesbury River. Changes to the natural flow of the river The river supplies water to Sydney's five million people as well as supplying agricultural production. This, c ...

Mammals Of Australia
The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that occupy similar niches, a phenomenon known as convergent evolution. For example, the top mammalian predators in Australia, the Tasmanian tiger and the marsupial lion, bore a striking resemblance to large canids such as the gray wolf and large cats respectively; gliding possums and flying squirrels have similar adaptations enabling their arboreal lifestyle; and the numbat and anteaters are both digging insectivores. Most of Australia's mammals are herbivores or omnivores. Evolutionary history The fossil record shows that monotremes have been present in Australia since the Early Cretaceous . Marsupials probably existed in Australia at least from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Reptiles Of Australia
The non-avian reptiles of Australia are a diverse group of animals, widely distributed across the continent. Three of the four reptile orders are represented: Testudines, Squamata and Crocodilia. The only missing extant order is Sphenodontia, containing the tuataras, which are endemic to New Zealand. Australia has over 860 species, a large number in comparison to other continents; for example, North America's total is about 280. The most species-rich group is Squamata, the snakes and lizards. They are especially diverse in the arid areas of Australia, where other fauna are scarcer. Spinifex grass is a major habitat which allows them to remain in a relatively cool, moist area. Australia has a large array of reptiles which can be dangerous to humans. The world's largest reptile, the saltwater crocodile (''Crocodylus porosus''), is native to the continent's north coastal area.

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Australia
Australia and its offshore islands and territories have 898 recorded bird species as of 2014. Of the recorded birds, 165 are considered vagrant or accidental visitors, of the remainder over 45% are classified as Australian endemics: found nowhere else on earth. It has been suggested that up to 10% of Australian bird species may go extinct by the year 2100 as a result of climate change. Australian species range from the tiny weebill to the huge, flightless emu. Many species of Australian birds will immediately seem familiar to visitors from the Northern Hemisphere: Australian wrens look and act much like northern wrens, and Australian robins seem to be close relatives of the northern robins. However, the majority of Australian passerines are descended from the ancestors of the crow family, and the close resemblance is misleading: the cause is not genetic relatedness but convergent evolution. For example, almost any land habitat offers a nice home for a small bird that specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
