Air Force Cross (United Kingdom)
The Air Force Cross (AFC) is a military decoration awarded to officers, and since 1993 other ranks, of the British Armed Forces, and formerly also to officers of the other Commonwealth of Nations, Commonwealth countries. It is granted for "an act or acts of exemplary gallantry while flying, though not in active operations against the enemy". A Medal bar, bar is added to the ribbon for holders who are awarded a further AFC. History The award was established on 3 June 1918, shortly after the formation of the Royal Air Force (RAF). It was originally awarded to RAF commissioned officers and Warrant Officers, but was later expanded to include Royal Navy and army aviation officers. While consistently awarded for service while "flying though not in active operations against the enemy", the AFC was originally awarded for "valour, courage or devotion to duty whilst flying" with many awards made for meritorious service over a period of time, rather than a specific act of bravery.

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sediment
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments. Classification Sediment can be classified based on its grain size, grain shape, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyodacite
Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. It is the extrusive equivalent of those plutonic rocks that are intermediate in composition between monzogranite and granodiorite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides. Description Under IUGS guidelines, rhyodacites are not formally defined in either the QAPF classification, used to classify igneous rocks by their mineral content, or the TAS classification, used to classify volcanic rocks chemically. However, the IUGS allows the use of the term to describe rocks close to the boundary between the rhyolite and dacite fields in each classification scheme. Rhyodacite then describes a fine-grained igneous rock containing between 20% and 60% quartz and in which plagioclase makes up about two-thirds of the total feldspar content. Such a rock will contain between 69% and 72% silica by weight. The U.S. Geological Survey defines rhyodacite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canberra Nature Park
The Canberra Nature Park is a series of thirty three separate protected areas in and around Canberra, Australian Capital Territory, ranging from bushland hills to lowland native grassland. Many of the areas have previously been cleared for grazing, but many are now being returned to native bushland through revegetation and rehabilitation programs. Canberra's inner hills Black Mountain, Mount Ainslie, Mount Majura, Mount Pleasant, Russell Hill, Red Hill, Mount Mugga, O'Connor Ridge, Bruce Ridge, Aranda Bushland, Mount Painter, The Pinnacle, Lyneham Ridge, Oakey Hill, Mount Taylor, Isaacs Ridge, Mount Stromlo, Mount Arawang, Neighbour Hill, Wanniassa Hill, and Narrabundah Hill are protected from development by the National Capital Plan and almost all are now part of the Canberra Nature Park system. These hills provide a scenic backdrop and natural setting for Canberra's urban areas, as originally set out in the Walter Burley Griffin Plan. Most people in Canberra live wit ...

Tuggeranong Hill
Tuggeranong Hill is located in Tuggeranong, Canberra. It is sometimes incorrectly referred to as Mount Tuggeranong due to its prominence. Lanyon Valley is almost completely surrounded by hills and mountains and consequently television transmissions from Black Mountain are affected. To overcome this, there is a broadcast translator on top of Tuggeranong Hill. There is a track to the repeater on top of Tuggeranong Hill for service vehicles that doubles as a fire trail. Tuggeranong Hill is part of the Canberra Nature Park. A walk to the top of Tuggeranong Hill provides views of the Lanyon Valley and of the rest of southern Canberra. Tuggeranong Hill stands 855 metres (2800 feet) above sea level.

Monaro Highway
Monaro Highway is a highway in Victoria, New South Wales, and the Australian Capital Territory, in Australia, linking in Victoria to Canberra in the Australian Capital Territory (ACT) via the Monaro region. From its southern terminus, it follows the nearby Cann River upstream towards the New South Wales border through heavily forested terrain. Within New South Wales (NSW), it makes its way through further forest before reaching the pastures typical of the Monaro. There are multiple towns and villages along the highway, including , , and . The terrain within the Monaro is largely hilly, and there are numerous crossings. The road also parallels the former Bombala railway line in several locations. Within the ACT, the road becomes a high volume roadway and serves the southern suburbs of Canberra. The highway has more recently had a grade-separated dual carriageway extension constructed within Canberra, as part of the Eastern Parkway construction project. It is designated part of r ...

DFC (UK)
The Distinguished Flying Cross (DFC) is the third-level military decoration awarded to officers, and since 1993 to other ranks, of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy". History The award was established on 3 June 1918, shortly after the formation of the Royal Air Force (RAF), with the Royal Warrant published on 5 December 1919. It was originally awarded to RAF commissioned and warrant officers, including officers in Commonwealth and allied forces. In March 1941 eligibility was extended to Naval Officers of the Fleet Air Arm, and in November 1942 to Army officers, including Royal Artillery officers serving on attachment to the RAF as pilots-cum-artillery observers. Posthumous awards were permitted from 1979. Since the 1993 review of the honours system as part of the drive to remove distin ...
