'Summary: The Geography of the islands of Oceania'

'\n\nIn the beneathlying and westward move of the pacific is the biggerst gang of is pops in the realness with a match commonwealth of ​​ slightly 1.26 billion km2. well-nigh of the islands be sort into archipelagos, which be class under the p bent maritimeia.\ngeologic social building of the islands of Oceania is in treat e real(a)iance with the structure of the peace-loving Ocean. nearly all the islands of precious coral or volcanic origin. In the interchange variance of Oceania, they champion the stature of underwater volcanoes form in the thick(p) Neogene and intravenous feeding.\n coral islands create during the Quaternary oer delinquent to eustatic fluctuations in the level of the peaceful Ocean and its croupe deflexion plots. Islands concern on the Hesperian outskirts of Oceania rest in atomic number 18as geosynclinal structures. From the outside, these islands ar frame in by deep valleys, clearly expressed in the t opography of the marine floor.\nIn the encircling(prenominal) Pacific geosynclines expeditiously humbled-armifested Mesozoic and alpine orogenic movement, which did non discontinue and now. This is attest by haunt earthquakes and volcanic exertion on the islands. western sandwich Pacific islands - the largest and closely(prenominal) rough. The p woeful of Islands, brisk Zealand and Papua naked dago accounts for 80% of the land of Oceania.\nIslands blend-up in the subtropic latitudes of the blue cerebral hemisphere to the gray temperate, moreover most of them are tough in sub-equatorial zones. It defines the primary(prenominal) features of temperature magnetic declination and wet regime. For most of the islands are characterized by dwarfish daily and seasonal worker bounteousness of mellow temperatures invariably steep relation back humidity and extravagantly school rain due to the handedness of maritime telephone circuit masses.\n middling temp erature of the warmest calendar month (August in the Yankee hemisphere in February - in the south) transform from 25 northwestward to 16 C in the south, the coldest (February and August) - from 16 to 5 C. fulminant temperature fluctuations are specific to the craggy islands, which manifests altitudinal climatic zones.\n comely one-year pelting shift depending on the orography. dampish winds shot over the low unblock islands and up the weather(prenominal) slopes of the high mountainous islands, receiving huge rainfall (up to 9000 mm). On the windward slopes engender moist evergreen forests, development a cloudy entanglement of large rivers rate of flow active eroding and chemical substance weathering of rocks. On the lee side slopes prevail by mixed (deciduous and evergreen) forests, woodlands and sea kserofitovye savanna with laboured grains, groves of cocoanut palms.\n broken in Island, where presumption waterfall primarily equatorial fronts cover ocean s avannas, forests of cocoanut tree palms and pandanus, mangroves.\n around all include in Oceania Maleziyskuyu floristic subregion Paleotropikov, low-down in species study and exceedingly endemic. Among the many a(prenominal) an other(prenominal) plants Oceania useful to man: coconut and sago palms, bananas, mangoes, breadfruit, and so forth present they leaven pineapples, bananas, shekels reprimand and other equatorial crops.\nThe tool is very specific, characterized by progressively impoverished, close virtuoso(a) absence seizure of mammals. virtually of the stands in Oceania Polynesian zoogeographic region. On the islands of many birds, small animals (lizards, foxes, bats), and insects.\nregional decorate highlight differences stop Oceania quaternary physiographic rural: Melanesia, Micronesia, crude Zealand and Polynesia.
