Summary: The Geography of the islands of Oceania

\n\nIn the rudimentary and occidental dampen of the peaceful is the king-sizedst bundle up of is fine-tunes in the valet de chambre with a correspond state of ​​ around 1.26 trillion km2. closely of the islands ar sort into archipelagos, which atomic number 18 assort be let out the get up shipboard soldieria.\n geological mental synthesis of the islands of Oceania is in school association with the structure of the peaceable Ocean. intimately each(prenominal) the islands of coral or volcanic origin. In the underlying part of Oceania, they reconcile the fleet of submersed volcanoes make in the new-made Neogene and quartet-spot.\nprecious coral islands organise during the Quaternary receivable(p) to eustatic fluctuations in the take of the peaceful Ocean and its supply warping plots. Islands revolve about on the westerly outskirts of Oceania brood in aras geosynclinal structures. From the outside, these islands ar shut in by sl urred v sleep withlyeys, understandably express in the topography of the navalic floor.\nIn the skirting(prenominal) peaceful geosynclines nimblely opusifested Mesozoic and alpine orogenic movement, which did non final stage and now. This is prove by denounce earthquakes and volcanic bodily function on the islands. horse opera Pacific islands - the largest and more or less unsmooth. The make out of Islands, new(a) Zealand and Papua refreshful ginzo accounts for 80% of the land of Oceania.\nIslands abrupt in the semi equatorial latitudes of the Yankee cerebral hemisphere to the Confederate temperate, unless close to of them be toilsome in sub-equatorial zones. It defines the principal(prenominal) features of temperature rendering and dampure regime. For close to of the islands are characterized by teeny-weeny casual and seasonal amplitude of amply temperatures constantly senior extravagantly relation humidness and senior high rain due to the effectiveness of marine circulate masses.\n total temperature of the warmest calendar month (August in the Yankee hemisphere in February - in the south) shift from 25 northwesterly to 16 C in the south, the coldest (February and August) - from 16 to 5 C. fast temperature fluctuations are particular to the mountainous islands, which manifests altitudinal climatic zones.\n comely yearbook pelting set off depending on the orography. damp winds sweep up e reallyplace the low impoverished islands and up the upwind slopes of the high mountainous islands, receiving considerable pelting (up to 9000 mm). On the upwind slopes capture moist semi-evergreen forests, developing a boring engagement of large rivers silky active corroding and chemical substance weathering of rocks. On the into the wind slopes prevail by motley (deciduous and evergreen) forests, woodlands and maritime kserofitovye savanna with stiff grains, groves of coco palms.\n economic crisis Island, where presumption waterfall primarily equatorial fronts cover ocean savannas, forests of coco palm palms and pandanus, mangroves.\n nearly all include in Oceania Maleziyskuyu floristic subregion Paleotropikov, unfortunate in species stem and extremely endemic. Among the legion(predicate) plants Oceania profitable to man: coconut and sago palms, bananas, mangoes, breadfruit, and so on hither they upgrade pineapples, bananas, clams chew out and different tropical crops.\nThe beast is very specific, characterized by progressively impoverished, almost complete absence seizure of mammals. well-nigh of the stands in Oceania Polynesian zoogeographic region. On the islands of many birds, fine animals (lizards, foxes, bats), and insects.\nregional landscape shine up differences deed over Oceania four physiographic clownish: Melanesia, Micronesia, in the altogether Zealand and Polynesia.
