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 yell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Dividing Range
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills. It runs roughly parallel to the east coast of Australia and forms the fifth-longest land-based mountain chain in the world, and the longest entirely within a single country. It is mainland Australia's most substantial topographic feature and serves as the definitive watershed for the river systems in eastern Australia, hence the name. The Great Dividing Range stretches more than from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, running the entire length of the eastern coastline through Queensland and New South Wales, then turning west across Victoria before finally fading into the Wimmera plains as rolling hills west of the Grampians region. The width of the Range varies from about to over .Shaw, John H., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlet (place), hamlets; in urban sociology or urban anthropology, it often contrasts with natural environment. The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCE led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment. Recent historical growth In 1950, 764 million people (or about 30 percent of the world's 2.5 billion people) lived in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney Water
Sydney Water, formally, Sydney Water Corporation, is a Government of New South WalesState-owned corporation, owned statutory authority, statutory corporation that provides potable drinking water, wastewater and some stormwater services to Sydney, Greater Metropolitan Sydney, the Illawarra and the Blue Mountains (New South Wales), 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 ''Metropolitan Water and Sewerage Amendment Act, 1888'' was enacted and repealed certain sections of the ''Sydney Corporation Act, 1879'' relating to water supply and sewerage, thereby transferring the property, powers and obligations from the City of Sydney, Municipal Council to the Board of Water Supply and Sewerage. During 2023 New South Wales state election, confidential documents from KPMG and Clayton Utz regarding the privatisation of Sydney Water were made public.

Parramatta River
The Parramatta River is an intermediate tide-dominated, Ria, drowned valley estuary located in Sydney, New South Wales, Australia. With an average Altitude, height, and depth, depth of , the Parramatta River is the main tributary of Sydney Harbour, a branch of Port Jackson. Secondary tributaries include the smaller Lane Cove River, Lane Cove and Duck River (New South Wales), Duck rivers. Formed by the confluence of Toongabbie Creek and Darling Mills Creek at North Parramatta, New South Wales, North Parramatta, the river flows in an easterly direction to a line between Yurulbin in Birchgrove, New South Wales, Birchgrove and Manns Point in Greenwich, New South Wales, Greenwich. Here, it flows into Port Jackson, about from the Tasman Sea. The total Drainage basin, 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 A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepean River
The Nepean River (Darug language, Darug: Yandhai), is a Perennial stream, major perennial river, located in the south-west and west of Sydney, New South Wales, Australia. The Nepean River, and, continuing by its downstream name, the Hawkesbury River, almost encircles the metropolitan region of Sydney. The headwaters of the Nepean River rise near Robertson, New South Wales, Robertson, about south of Sydney and about from the Tasman Sea. The river flows north in an unpopulated water catchment area into Upper Nepean Scheme#Nepean Dam, 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, New South Wales, Camden and the city of Penrith, New South Wales, Penrith, south of which flowing through the Nepean Gorge. Near Wallacia, New South Wales, Wallacia it is joined by the dammed Warragamba River; and north of Penrith, near Yarramundi, New South Wales, Yarramundi, at its confluence wi ...

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. Of the three mammal subclasses, monotremes, marsupials, and placentals, Australia is one of the only countries home to all three. 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 s ... [...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. Triodia (plant genus), 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 Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...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] |
Soils
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Tree
''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'' and ''Angophora'', they are commonly known as eucalypts or "gum trees". Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil Gland (botany), glands. The sepals and petals are fused to form a "cap" or Operculum (botany), operculum over the stamens, hence the name from Greek ''eû'' ("well") and ''kaluptós'' ("covered"). The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Many eucalypt species have adapted to wildfire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
