Lake C
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suburbs And Localities In The Shire Of Mundaring
A suburb (more broadly suburban area) is an area within a metropolitan area, which may include commercial and mixed-use, that is primarily a residential area. A suburb can exist either as part of a larger city/urban area or as a separate political entity. The name describes an area which is not as densely populated as an inner city, yet more densely populated than a rural area in the countryside. In many metropolitan areas, suburbs exist as separate residential communities within commuting distance of a city (cf "bedroom suburb".) Suburbs can have their own political or legal jurisdiction, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries, suburban areas are defined in contrast to central or inner city areas, but in Australian English and South African English, ''suburb'' has become largely synonymous with what i ...

James Drummond (botanist)
James Drummond (late 1786 or early 1787 – 26 March 1863) was an Australian botanist and naturalist who was an early settler in Western Australia. Early life James Drummond was born in Inverarity, near Forfar, Angus, Scotland, the eldest son of Thomas Drummond, a gardener and botanist. His younger brother Thomas Drummond (1793–1835) was also a botanist. The latter emigrated to Cuba and died there. Both brothers originally worked with their father on the Fothringham estate in Inverarity. He was baptised on 8 January 1787. His father, Thomas Drummond, was a gardener at Fotheringham estate. Little is known of his early life, but he certainly followed the usual course of apprenticeship leading to his "qualification" as a gardener. In 1808, he was employed by Mr Dickson (most probably George Dickson of Leith Walk, Edinburgh). In the mid-1808, Drummond (aged 21) he was appointed curator of the botanic garden that was being established by the Cork Institution, in the cit ...

Midland, Western Australia
Midland is a suburb in the Perth metropolitan region, as well as the regional centre for the City of Swan local government area that covers the Swan Valley and parts of the Darling Scarp to the east. It is situated at the intersection of Great Eastern Highway and Great Northern Highway. Its eastern boundary is defined by the Roe Highway. Midland is almost always regarded as a suburb of Perth, being only away from the city centre. History Railway Midland was the site of the Midland Railway Workshops - the main workshops for the Western Australian Government Railways (WAGR) for over 80 years. It was also a terminus for the Midland Railway Company. At the end of the Second World War it was the junction of the Midland Railway, the Upper Darling Range Railway, and the main Eastern Railway.

Greenmount, Western Australia
Greenmount is a locality and a geographical feature in the Shire of Mundaring, Western Australia, on the edge of the Darling Scarp. It is a vital point in the transport routes from the Swan Coastal Plain into the hinterland of Western Australia. Early colonial history Ensign Robert Dale reached the summit on 18 October 1829. John Septimus Roe communicated with Dale over the York Road he had used the name Green Mount. In the era of the Swan River Colony the name "Greenmount" was used for two points on the Darling Scarp. In the 1840s the York Road was known as York Greenmount, and the road further north along the Scarp was known as Toodyay Greenmount. It is possible that these two locations might have had slightly different coloured foliage compared to the grey blue green colour of the Scarp. During the convict era, in 1854 Edward Du Cane was the supervisor of the building of a convict depot on the slopes of the hill. In the 1870s a government bluestone quarry was develope ...

Soil Ph
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element i ... ... [...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] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Mount Dale, Western Australia
Mount Dale is a mountain in Western Australia about east of Armadale in the Shire of Beverley. At high, it is one of the highest points in the Darling Scarp. It is best known for its walk track, which forms part of the Bibbulmun Track. The track leads from a parking and picnic area to the summit, passing through of jarrah forest, which is coloured by a host of wildflowers in spring. South of Mundaring Weir, Mount Dale is visible when looking south-southeast from Glen Forrest outside Helena College on Bilgoman Road. Mount Dale was once the site of a fire lookout tower as it provides almost uninterrupted 360° views over the National Park and surrounding State Forest areas. a 1925 reflection on being in the fire tower This has now been replaced by a communications tower which obstructs the 360° panorama, though the footings of the old lookout tower and associated equipment are still visible among the undergrowth and stunning panoramic views are available from the parkin ...
