S. Warren Carey
Samuel Warren Carey AO (1 November 1911, in Campbelltown – 20 March 2002, in Hobart) was an Australian geologist and a professor at the University of Tasmania. He was an early advocate of the theory of continental drift. His work on plate tectonics reconstructions led him to develop the Expanding Earth hypothesis. Biography Samuel Warren Carey was born in New South Wales and grew up on a farm three miles from Campbelltown. The family was to move to the town centre, saving the young Carey the walk to school. An interest in physics and chemistry during high school was to lead to selection of both subjects when he attended the University of Sydney in 1929. Mathematics was required and he was encouraged to study geology as his fourth subject, a department still under the influence of retired Professor Edgeworth David. He started a student Geology club as he became attracted to the subject's mixture of laboratory and field work; David gave the inaugural speech. Along ...

Campbelltown, New South Wales
Campbelltown is a suburb located on the outskirts of the metropolitan area of Sydney, New South Wales, Australia. It is located in Greater Western Sydney south-west of the Sydney central business district by road. Campbelltown is the administrative seat of the local government area of the City of Campbelltown. It is also acknowledged on the register of the Geographical Names Board of New South Wales as one of only four cities within the Sydney metropolitan area. Campbelltown gets its name from Elizabeth Campbell, the wife of former Governor of New South Wales Lachlan Macquarie. Originally called Campbell-Town, the name was later simplified to the current Campbelltown. History The area that later became Campbelltown was inhabited prior to European settlement by the Tharawal people. Not long after the arrival of the First Fleet in Sydney in 1788, a small herd of six cattle escaped and weren't seen again by the British settlers for seven years. They were spotted, howeve ...

Plate Tectonic
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or '' transform''. Earthquakes, volcanic activity, mountain-building, and oceanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Officer Of The Order Of Australia
The Order of Australia is an honour that recognises Australian citizens and other persons for outstanding achievement and service. It was established on 14 February 1975 by Elizabeth II, Queen of Australia, on the advice of the Australian Government. Before the establishment of the order, Australian citizens received British honours. The Monarch of Australia is sovereign head of the order, while the Governor-General of Australia is the principal companion/dame/knight (as relevant at the time) and chancellor of the order. The governor-general's official secretary, Paul Singer (appointed August 2018), is secretary of the order. Appointments are made by the governor-general on behalf of the Monarch of Australia, based on recommendations made by the Council of the Order of Australia. Recent knighthoods and damehoods were recommended to the governor-general by the Prime Minister of Australia. Levels of membership The order is divided into a general and a military divis ...

Australia Day
Australia Day is the official national day of Australia. Observed annually on 26 January, it marks the 1788 landing of the First Fleet at Sydney Cove and raising of the Union Flag by Arthur Phillip following days of exploration of Port Jackson in New South Wales. In present-day Australia, celebrations aim to reflect the diverse society and landscape of the nation and are marked by community and family events, reflections on Australian history, official community awards and citizenship ceremonies welcoming new members of the Australian community. The meaning and significance of Australia Day has evolved and been contested over time, and not all states have celebrated the same date as their date of historical significance. The date of 26 January 1788 marked the proclamation of British sovereignty over the eastern seaboard of Australia (then known as New Holland). Although it was not known as Australia Day until over a century later, records of celebrations on 26 January d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tectonics
Tectonics (; ) are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles is essential to geomorphologists to explain erosion patterns and other Earth surface features. Main types of tectonic regime Extensional tectonics Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere. This type of tectonics is ...

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or '' window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular '' klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind ...

Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expanding Earth
The expanding Earth or growing Earth hypothesis argues that the position and relative movement of continents is at least partially due to the volume of Earth increasing. Conversely, geophysical global cooling was the hypothesis that various features could be explained by Earth contracting. Although it was suggested historically, since the recognition of plate tectonics in the 1970s, scientific consensus has rejected any significant expansion or contraction of Earth. Different forms of the hypothesis Expansion with constant mass In 1834, during the second voyage of HMS ''Beagle'', Charles Darwin investigated stepped plains featuring raised beaches in Patagonia which indicated to him that a huge area of South America had been "uplifted to its present height by a succession of elevations which acted over the whole of this space with nearly an equal force." While his mentor Charles Lyell had suggested forces acting near the crust on smaller areas, Darwin hypothesized that uplift a ...

Folding Kayak
A folding kayak is a direct descendant of the original Inuit kayak made of animal skins stretched over frames made from wood and bones. A modern folder has a collapsible frame made of some combination of wood, aluminium and plastic, and a skin made of a tough fabric with a waterproof coating. Many have integral air chambers inside the hull, making them virtually unsinkable. History First models The first workable folding kayak was built by Alfred Heurich in 1905, a German architectural student. Heurich paddled his creation on the Isar River near Munich and took out a patent on the design, called the Delphin (German: Dolphin), the following year. The Delphin had a bamboo frame with a sailcloth hull stretched over it. It could be folded up and carried in three bags, each weighing less than . The folding kayak was made commercially successful by Johannes Klepper, whose factory was at Rosenheim, Germany. Klepper kayaks were very popular for their compact size and ease of transport ...
