Bents Basin
Bents Basin is a protected nature reserve and state park near Wallacia, New South Wales, Australia in the Sydney metropolitan area. The lake basin, which formed at the efflux of the Nepean River from the Hawkesbury Sandstone (Sydney sandstone) gorge, is a popular swimming hole with a camping area and an education centre used by local school groups. Also featuring a large woodland area and native wildlife, the reserve is the only picnic area along the Nepean River and it is one of the most popular water-based picnic parks in Greater Western Sydney. History Aboriginal Australians were denizens of the area due to its vicinity to the Nepean River, which featured food and water. The Basin is believed to have been a traditional meeting and trading place between Aboriginal groups. Having spiritual and cultural significance to Aboriginal communities, camps were used to provide an opportunity for Aboriginal people to connect with each other and their culture. Bents Basin was discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the ''drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar but n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Basin
Sedimentary basins are region-scale depressions of the Earth's crust where subsidence has occurred and a thick sequence of sediments have accumulated to form a large three-dimensional body of sedimentary rock. They form when long-term subsidence creates a regional depression that provides Accommodation (geology), accommodation space for accumulation of sediments. Over millions or tens or hundreds of millions of years the deposition of sediment, primarily gravity-driven transportation of water-borne eroded material, acts to fill the depression. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction (geology), compaction and lithification that transform them into sedimentary rock. Sedimentary basins are created by deformation of Earth's lithosphere in diverse geological settings, usually as a result of plate tectonics, plate tectonic activity. Mechanisms of crustal deformation that lead to subsidence and sedimentary basin formati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wianamatta Shale
The Wianamatta Group is a geological feature of the Sydney Basin, New South Wales, Australia that directly overlies the older (but still Triassic in age) Hawkesbury sandstone and generally comprise fine grained sedimentary rocks such as shales and laminites as well as less common sandstone units. Group The Wianamatta Group is made up of the following units (listed in stratigraphic order): * Bringelly Shale * Minchinbury Sandstone * Ashfield Shale The Wianamatta Group was derived from the Aboriginal name for South Creek. It was officially established in 1952, fully attested in 1954 and further amended in 1979. Geology The Wianamatta Group is the youngest geological layer member of the Sydney Basin, and therefore lies at the highest point as the highest layer member. It was deposited in connection with a large river delta, which shifted over time from west to east. This is evidenced by the sequence of strata, which clearly show the transition from marine deposits in front of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddock
A paddock is a small enclosure for horses. In the United Kingdom, this term also applies to a field for a general automobile racing competition, particularly Formula 1. Description In Canada and the United States of America, a paddock is a small enclosure used to keep horses. In the United Kingdom, this term has a similar meaning, and also applies to a field for a general automobile racing competition, particularly Formula 1. The most common design provides an area for exercise and is often situated near the stables. Larger paddocks may have grass maintained in them, but many are dirt or a similar natural surface. In those cases drainage and a top layer of sand are often used to keep a suitable surface in the paddock. In the American West, such an enclosure is often called a corral, and may be used to contain cattle or horses, occasionally other livestock. The word paddock is also used to describe other small, fenced areas that hold horses, such as a saddling paddock at a racetra ...

Sydney Central Business District
The Sydney central business district (CBD) is the historical and main Central business district, commercial centre of Sydney. The CBD is Sydney's city centre, or Sydney City, and the two terms are used interchangeably. Colloquially, the CBD or city centre is often referred to simply as "Town" or "the City". The Sydney city centre extends southwards for about from Sydney Cove, the point of first European settlement in which the Regions of Sydney, Sydney region was initially established. Due to its pivotal role in Australia's early history, it is one of the oldest established areas in the country. Geographically, its north–south axis runs from Circular Quay in the north to Central railway station, Sydney, Central railway station in the south. Its east–west axis runs from a chain of parkland that includes Hyde Park, Sydney, Hyde Park, The Domain, Sydney, The Domain, Royal Botanic Gardens, Sydney, Royal Botanic Gardens and Farm Cove, New South Wales, Farm Cove on Port Jackson, S ...

Penrith, New South Wales
Penrith is a city in New South Wales, Australia, located in Greater Western Sydney, 55 kilometres (31 mi) west of the Sydney central business district on the banks of the Nepean River, on the outskirts of the Cumberland Plain. Its elevation is 32 metres (105 ft). Penrith is the administrative centre of the Local government in Australia, local government area of the City of Penrith. The Geographical Names Board of New South Wales acknowledges Penrith as one of only four List of cities in Australia, cities within the Greater Sydney metropolitan area. History Indigenous settlement Prior to the arrival of the Europeans, the Penrith area was home to the Mulgoa tribe of the Darug people. They lived in makeshift huts called ''gunyahs'', hunted native animals such as kangaroos, fished in the Nepean River, and gathered local fruits and vegetables such as yams. They lived under an elaborate system of law which had its origins in the Dreamtime. Most of the Mulgoa were kil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hawkesbury River
The Hawkesbury River, or Hawkesbury-Nepean River, is a river located northwest of Sydney, New South Wales, Australia. The Hawkesbury River and its associated main tributary, the Nepean River, almost encircle the metropolitan region of Sydney. The Hawkesbury River has its origin at the confluence of the Nepean River and the Grose River, to the north of Penrith and travels for approximately in a north–easterly and then a south–easterly direction to its mouth at Broken Bay, about from the Tasman Sea. The Hawkesbury River is the main tributary of Broken Bay. Secondary tributaries include Brisbane Water and Pittwater, which, together with the Hawkesbury River, flow into Broken Bay and thence into the Tasman Sea north of Barrenjoey Head. The total catchment area of the river is approximately and the area is generally administered by the Hawkesbury–Nepean Catchment Management Authority. The land adjacent to the Hawkesbury River was occupied by Aboriginal peoples: th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Schinus Areira
''Schinus molle'' (Peruvian pepper, also known as American pepper, Peruvian peppertree, escobilla, false pepper, rosé pepper, molle del Peru, pepper tree, (Archived bWebCite peppercorn tree, California pepper tree, pirul (in Mexican Spanish site), Peruvian mastic, Anacahuita o Aguaribay and Pepperina) is an evergreen tree that grows to 15 meters (50 feet). It is native to an area from the Peruvian Andes to southern Brazil. The bright pink fruits of ''Schinus molle'' are often sold as "pink peppercorns" although ''S. molle'' is unrelated to true pepper (''Piper nigrum''). The word ''molle'' in ''Schinus molle'' comes from ''mulli'', the Quechua word for the tree. The tree is host to the pepper-tree moth, '' Bombycomorpha bifascia''. Description ''Schinus molle'' is a quick growing evergreen tree that grows up to 15 meters (50 feet) tall and wide. It is the largest of all ''Schinus'' species and potentially the longest lived. The upper branches of the tree tend to droop. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
