Regions Of Indonesia
This is a list of some of the regions of Indonesia. Many regions are defined in law or regulations by the central government. At different times of Indonesia's history, the nation has been designated as having regions that do not necessarily correlate to the current administrative or physical geography of the territory of the nation. Geographical units According to ISO 3166-2:ID, Indonesia is divided into seven geographical units, with each unit consisting of major islands or an island group. These geographical units are as follows: Eastern Indonesia and Western Indonesia During the last stages of the Dutch colonial era, the area east of Java and Kalimantan was known as the Great East and later known as Eastern Indonesia. On 24 December 1946, the State of East Indonesia was formed covering the same area (excluding Western New Guinea). It was a component of the United States of Indonesia, and was dissolved into the unitary Republic of Indonesia in August 1950. Currently, E ...

Volcanoes Of Sulawesi
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Mountains Of Sulawesi
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Stratovolcanoes Of Indonesia
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcanoes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Geological Survey
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research. The BGS headquarters are in Keyworth, Nottinghamshire, England. Its other centres are located in Edinburgh, Wallingford, Cardiff and London. The current motto of the BGS is: ''Gateway to the Earth''. History and previous names The Geological Survey was founded in 1835 by the Board of Ordnance as the Ordnance Geological Survey, under Henry De la Beche. This was the world's first national geological survey. It remained a branch of the Ordnance Survey for many years. In 1965, it was merged with the Geological Museum and Overseas Geological Surveys, under the name of Institute of Geological Sciences. On 1 January 1984, the institute was renamed the British Geological Survey (and often referred to as the BGS), a name still carried today. Competenc ...

List Of Volcanoes In Indonesia
The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatoa for its global effects in 1883, the Lake Toba Caldera for its supervolcanic eruption estimated to have occurred 74,000 years before present which was responsible for six years of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815. Volcanoes in Indonesia are part of the Pacific Ring of Fire. The 150 entries in the list below are grouped into six geographical regions, four of which belong to the volcanoes of the Sunda Arc trench system. The remaining two groups are volcanoes of Halmahera, including its surrounding volcanic islands, and volcanoes of Sulawesi and the Sangihe Islands. The latter group is in one volcanic arc together with the Philippine volcanoes. The most active volcano is Mount Merapi on Java. ...

Spectral Tarsier
The spectral tarsier (''Tarsius spectrum'', also called ''Tarsius tarsier'') is a species of tarsier found on the island of Selayar in Indonesia. It is apparently less specialized than the Philippine tarsier or Horsfield's tarsier; for example, it lacks adhesive toes. It is the type species for the genus ''Tarsius''. While its range used to also include the population on nearby southwestern Sulawesi, this population has been reclassified as a separate species, ''Tarsius fuscus''. Some of the earlier research published on ''Tarsius spectrum'' refers to the taxon that was recently reclassified and elevated to a separate species, the Gursky's spectral tarsier (''Tarsius spectrumgurskyae''). Taxonomy and evolution "Tarsiers were once thought to be of the Strepsirrhini suborder, grouped with Lemuroidea and Lorisidae because of their similar appearance and because they have a small stature and are also nocturnal. It has been decided that tarsiers are members of the suborder haplorr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celebes Crested Macaque
The Celebes crested macaque (''Macaca nigra''), also known as the crested black macaque, Sulawesi crested macaque, or the black ape, is an Old World monkey that lives in the Tangkoko reserve in the northeastern tip of the Indonesian island of Sulawesi (Celebes), as well as on smaller neighboring islands. Description Locally known as ''yaki'' or ''wolai'', its skin and hairless face is, with the exception of some white hair in the shoulder range, entirely jet black. Unusual for a primate, it has striking reddish-brown eyes. The long muzzle with high cheeks and the long hair tuft, or crest, at the top of the head are remarkable features. It has an "apelike" appearance due to its almost non-existent, non-visible, vestigial tail stub of only approximately . With a total body length of to and a weight of to , it is one of the smaller macaque species. Its life expectancy is estimated at 15–20 years in the wild. Ecology The Celebes crested macaque is a diurnal rain forest dwell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
