Lake Tritriva
Lake Tritriva is a volcanic lake in southwest-central Madagascar, in the region of Vàkinankàratra, located near the village of Belazao. In a distance of 15 km from Antsirabe, it is easy to reach by the National Road 34. There's a strict Fady (taboo) for this lake and swimming is not allowed. The lake fills an extinct crater in a region notable also for the presence of many hot springs. It sits in the vent of an oval volcanic cone enclosed in vertical gneiss cliffs. The rim of the cone is about above sea level, while the surface of the lake is approximately below the rim. The lake's water level drops during the rainy season and rises when the monsoon rains have ceased.

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Fady (taboo)
In Malagasy culture, ''fady'' () are a wide range of cultural prohibitions or taboos. People, places, actions or objects may be the subject of ''fady'', which vary by region within Madagascar. The taboos are believed to be enforced by supernatural powers, and are particularly connected with Malagasy ancestor worship. Although some are held nationwide, others may be particular to regions, villages or even individual families. ''Fady'' are an integral part of Malagasy identity and play an important part in community and identity formation. The word is a descendant of Proto-Austronesian *''paliSi'' (compare with Malay ''pemali'', Old Javanese ''pali-pali''). Common prohibitions include those against pointing at a tomb, against the eating of eels by pregnant women and, for onlookers, against describing a newborn baby as ugly. New ''fady'' are created constantly. When a new initiative or business is started, a ritual offering (''joro'') must be made to prove that it is not ''fady''. Thos ...

Hot Spring
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its ...

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...

Madagascar Stonechat
The Madagascar stonechat (''Saxicola sibilla'') is a species of stonechat, endemic to Madagascar. It is a small bird, closely similar to the African stonechat in both plumage and behaviour, but distinguished from it by the more extensive black on the throat and minimal orange-red on the upper breast of the males.Urquhart, E., & Bowley, A. (2002): ''Stonechats. A Guide to the Genus Saxicola''. Christopher Helm, London. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Madagascar stonechat in his ''Ornithologie'' based on a specimen collected in Madagascar. He used the French name ''Le traquet de Madagascar'' and the Latin ''Rubetra Madagascariensis''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. ...

Malagasy Kestrel
The Malagasy kestrel (''Falco newtoni''), also known as the Madagascar kestrel, Malagasy spotted kestrel, Newton's kestrel, Madagascar spotted kestrel, ''katiti'' ( Creole) or ''hitsikitsika'' ( Malagasy), is a small bird of prey of the genus '' Falco''. It is named after British ornithologist Edward Newton. It occurs in two subspecies on Madagascar and at Aldabra. The race from Aldabra is also called Aldabra kestrel (''Falco newtoni aldabranus''). Its closest living relative is the Seychelles kestrel; they were at one time considered conspecific. Their common ancestors appear to have diverged very recently, probably less than 1 million years ago during the Early or Middle Pleistocene. The Mauritius kestrel is more distantly related.(Groombridge ''et al.'' 2002) Description It can reach a size of 30 cm. The wings are 180 mm to 195 mm at the males and 188 mm to 203 mm at the females. The males can reach a weight between 112 and 118 grams. The weight of the ...
