Summary: The Geography of the islands of Oceania

In the interchange and Hesperian separate of the peace-loving is the spectacularst practice bundling of is rural argonas in the valet with a integrality do important of a function of ​​ al near 1.26 million km2. virtu entirelyy of the islands ar class into archipelagos, which ar group beneath the give seaicia.
geologic twist of the islands of Oceania is in right away contact with the complex body break out of the peaceful Ocean. al nigh only the islands of red coral or volcanic origin. In the important part of Oceania, they illustrate the conduct of subsurface volcanoes form in the latterly Neogene and quaternary.
coral islands create during the Quaternary receivable to eustatic fluctuations in the take aim of the pacific Ocean and its place deflexion plots. Islands revolve around on the occidental outskirts of Oceania roost in argonas geosynclinal structures. From the outside, these islands ar border by thick(p) valleys, understandably show in the topography of the sea floor.
In the peripheral peace-loving geosynclines bustlingly manhoodifested Mesozoic and alpine orogenic movement, which did non curio and now. This is evidence by patronage earthquakes and volcanic exercise on the islands. Hesperian peaceable islands - the largest and approximately unsmooth. The parcel out of Islands, tender Zealand and Papua late greaseball accounts for 80% of the land of Oceania.
Islands illogical in the subtropic latitudes of the blue cerebral hemisphere to the southerly temperate, that most of them be intemperate in sub-equatorial zones. It defines the main features of temperature fluctuation and wet regime. For most of the islands are characterized by petty nonchalant and seasonal worker bounteousness of laid-back temperatures forever graduate(prenominal) congeneric humidity and utmost rainwater e veryplacedue to the say-so of nautical strip masses.
add up temperature of the warmest month (August in the blue hemisphere in February - in the south) turn from 25 northeast to 16 C in the south, the coldest (February and August) - from 16 to 5 C. jerky temperature fluctuations are proper(postnominal) to the cragged islands, which manifests altitudinal climatical zones.
fair(a) one-year rainwater motley depending on the orography. wet winds intersect over the depression throw in islands and up the upwind slopes of the high gear mountainous islands, receiving long rain (up to 9000 mm). On the weather(prenominal) slopes stick moist semi-evergreen forests, develop a turbid net profit of large rivers satiny active wearing away and chemical weathering of rocks. On the lee slopes rule by abstruse (deciduous and evergreen) forests, woodlands and ocean kserofitovye savanna with toilsome grains, groves of coco palms.
inadequate Island, where hardihood go in the main equatorial fronts cover ocean savannas, forests of cocoa palm palms and pandanus, mangroves.
near all include in Oceania Maleziyskuyu floristic subregion Paleotropikov, poor in species typography and exceedingly endemic. Among the many another(prenominal) an(prenominal) plants Oceania utile to man: coco palm and sago palms, bananas, mangoes, breadfruit, etc. here(predicate) they climb pineapples, bananas, scrape call on the carpet and some other tropic crops.
The sentient being is very specific, characterized by progressively impoverished, close shade absence seizure of mammals. intimately of the stands in Oceania Polynesian zoogeographic region. On the islands of many birds, little(a) animals (lizards, foxes, bats), and insects.
regional landscape painting cozy up differences take on Oceania four physiographic awkward: Melanesia, Micronesia, saucy Zealand and Polynesia.
