Mount Warning
Mount Warning ( Bundjalung: ''Wollumbin''), a mountain in the Tweed Range in the Northern Rivers region of New South Wales, Australia, was formed from a volcanic plug of the now-gone Tweed Volcano. The mountain is located west-south-west of Murwillumbah, near the border between New South Wales and Queensland. Lieutenant James Cook saw the mountain from the sea and named it Mount Warning. Shield volcano Wollumbin is the central volcanic remnant of an ancient shield volcano, the Tweed Volcano, which would have been about above sea level or just under twice the height of the current mountain.The Caldera of the Mount Warning Shield Volcano. rochureNew South Wales National Parks and Wildlife Service. 1990. This volcano last erupted around 23 million years ago. As the mountain's central vent cooled it shrank, forming a depression at the top that has greatly eroded. Today the vast areas that were part of the volcano include many mountains and ranges at some distance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Languages Of Australia
The Indigenous languages of Australia number in the hundreds, the precise number being quite uncertain, although there is a range of estimates from a minimum of around 250 (using the technical definition of 'language' as non-mutually intelligible varieties) up to possibly 363. The Indigenous languages of Australia comprise numerous language family, language families and language isolate, isolates, perhaps as many as 13, spoken by the Aboriginal Australians, Indigenous peoples of mainland Australia and a few nearby islands. The relationships between the language families are not clear at present although there are proposals to link some into larger groupings. Despite this uncertainty, the Indigenous Australian languages are collectively covered by the technical term "Australian languages", or the "Australian family". The term can include both Tasmanian languages and the Kalaw Lagaw Ya, Western Torres Strait language, but the Genetic relationship (linguistics), genetic relations ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Mount Wollumbin Hip-pocket Frog
''Assa wollumbin'', the Wollumbin pouched frog or Mount Wollumbin hip-pocket frog, is a species of small, terrestrial frog endemic to New South Wales, Australia. It is restricted to the slopes of Mount Warning (Wollumbin), where it inhabits rainforest habitat. Previously considered a population of the pouched frog (''A. darlingtoni''), which was thought to be the only species in the genus, it was described as a new species in 2021 following a rangewide genetic analysis of ''A. darlingtoni'', which found the Wollumbin population to be sufficiently genetically distinct; it is also physically smaller than ''A. darlingtoni''. Despite its distinctiveness, it is separated from populations of ''A. darlingtoni'' by only ; in relation to the ancient Tweed Volcano, ''A. darlingtoni'' inhabits the former caldera wall while ''A. wollumbin'' inhabits the former volcanic plug that is now Mt. Wollumbin. As with ''A. darlingtoni'', it shares the unusual parental care where male individuals carry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Massif
A massif () is a principal mountain mass, such as a compact portion of a mountain range, containing one or more summits (e.g. France's Massif Central). In mountaineering literature, ''massif'' is frequently used to denote the main mass of an individual mountain. As a purely scientific term in geology, however, a "massif" is separately and more specifically defined as a section of a planet's crust (geology), crust that is demarcated by geologic fault, faults or lithospheric flexure, flexures. In the plate tectonics, movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology. The word "massif" originates from French (in which the word also means "massive"), where it is used to refer to a large mountain mass or compact group of connected mountains forming an independent portion of a range. The Cydonia (regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tweed River, New South Wales
The Tweed River is a river situated in the Northern Rivers region of New South Wales, Australia. From the middle reaches of its course, the state boundary between New South Wales and Queensland is located approximately north. The river rises on the eastern slopes of the Great Dividing Range; with its watershed bordered by the McPherson, Burringbar, Condong and Tweed ranges and containing a catchment area of . The river flows generally north east, joined by eight tributaries including the Oxley and Rous rivers before reaching its mouth at its confluence with the Coral Sea of the South Pacific Ocean, south of Point Danger; descending over its course. On its journey, it passes through the major urban centres of Murwillumbah and Tweed Heads. The river's drainage basin consists mostly of the erosion caldera of the Tweed Volcano, a huge extinct volcano of which Mount Warning is the volcanic plug. The Tweed River area has a fine subtropical climate, high rainfall and fertile v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. An eruption that ejects large volumes of magma over a short period of time can cause significant detriment to the structural integrity of such a chamber, greatly diminishing its capacity to support its own roof and any substrate or rock resting above. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given window of 100 years. Only eight caldera-forming collapses are known to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
