Leizhou Peninsula
The Leizhou Peninsula, alternately romanized as the Luichow Peninsula, is a peninsula in the southernmost part of Guangdong province in South China. History Qing naval forces were stationed at the Leizhou Peninsula. During the 19th century, the area was a hotbed of piracy, many pirates, such as Zheng Yi and Wu Shi Er, were based in the area. Geography The Leizhou Peninsula is the third largest peninsula in China with an area of c. located on the southwestern end of Zhanjiang, Guangdong with the Gulf of Tonkin to the west and the 30 km wide Qiongzhou Strait to the south, separating the peninsula from Hainan Island. Geologically, basalt terraces account for 43% of the peninsula's area. The rest is divided up between marine terraces (27%) and alluvial plains (17%). Leizhou Peninsula is dotted with a few dormant volcanoes, beaches, and low-lying diluvial plains. Leizhou has two separate volcanic fields: a Pleistocene– Holocene field at the norther ...

Chinese Postal Romanization
Postal romanization was a system of transliterating Chinese place names developed by postal authorities in the late 19th and early 20th centuries. For many cities, the corresponding postal romanization was the most common English-language form of the city's name from the 1890s until the 1980s, when postal romanization was replaced by pinyin, but the system remained in place on Taiwan until 2002. In 1892, Herbert Giles created a romanization system called Nanking syllabary. The Imperial Maritime Customs Post Office would cancel postage with a stamp that gave the city of origin in Latin letters, often romanized using Giles's system. In 1896, the Customs Post was combined with other postal services and renamed the Chinese Imperial Post. As a national agency, the Imperial Post was an authority on Chinese place names. When the Wade–Giles system of romanization became widespread, some argued that the post office should adopt it. This idea was rejected at a conference held in ...

Volcano
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 pla ...

Indo-Pacific Humpback Dolphin
The Indo-Pacific humpback dolphin (''Sousa chinensis'') is a species of humpback dolphin inhabiting coastal waters of the eastern Indian and western Pacific Oceans. This species is often referred to as the Chinese white dolphin in mainland China, Macao, Hong Kong, Taiwan and Singapore as a common name. Some biologists regard the Indo-Pacific dolphin as a subspecies of the Indian Ocean humpback dolphin (''S. plumbea'') which ranges from East Africa to India. However, DNA testing studies have shown that the two are distinct species. A new species, the Australian humpback dolphin (''S. sahulensis''), was split off from ''S. chinensis'' and recognized as a distinct species in 2014. Nevertheless, there are still several unresolved issues in differentiation of the Indian Ocean-type and Indo-Pacific-type humpback dolphins. Taxonomy Two subspecies of the Indo-Pacific humpback dolphin are currently recognized: *''S. c. chinensis'', or the Chinese humpback dolphin *''S. c. taiwanensis' ...

Tianyang (volcano)
Tianyang District (; Standard Zhuang: ; Youjiang Zhuang: ) is a district in western Guangxi, China. It is under the administration of the prefecture-level city of Baise. History Tianyang County was formed in 1935 by combining Fengyi County () and Enyang County () with the county seat in Napo () and in 1954 the county seat was moved to Tianzhou (). In 1935 the population was 135,071. In August 2019, the county was converted into a district. Administrative divisions From June 21, 2005, there are 7 towns and 3 townships in the county: Towns: * Tianzhou (田州镇)(63k) * Napo (那坡镇)(32k) * Pohong (坡洪镇)(37k) * Naman (那满镇)(23k) * Baiyu (百育镇)(27k) * Yufeng (玉凤镇)(38k) * Toutang (头塘镇)(24k) Townships: * Dongjing Township (洞靖乡)(32k) * Babie Township (巴别乡)(20k) * Wucun Township (五村乡)(27k)(98% Zhuang) Demographics Tianyang's population was 338,300 in 2010. 90.2% of the people belong to the Zhuang ethnic group, and speak Youjiang Zh ...

Stratovolcano
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 volcano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by the shores of South China (hence the name), in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan (e.g. the Mindoro and Balabac Straits), the Strait of Malacca via the Singapore Strait, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are also part of the South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea. The South China Sea is a region of tremendous economic and geostrategic importance. One-third of the world's maritime s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithosphere
A lithosphere () is the rigid, outermost rocky shell of a terrestrial planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of up to thousands of years or more. The crust and upper mantle are distinguished on the basis of chemistry and mineralogy. Earth's lithosphere Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long periods of geologic time in which it deforms elastically and through brittle failure, while the asthenosphere deforms viscously and accommodates strain through plastic deformation. The thickness of the lithosphere is thus considered to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.
