The Arctic Ocean

KweArctic Ocean iri mu kweArctic, zvayo chinokosha. Nyika zvakamupoteredza zvinenge kubva kumativi ose. It kunyanya anosarudza hunhu waro rwokuzvarwa masango: okunze, hydrological zvinhu. KweArctic Ocean iduku zvose nyanza panyika.

Border mvura okurutivi ari Air Peninsula kuna Faroe uye Shetland Islands, muGungwa Bering, ari Davis Strait, uye Danish. Kuburikidza pakamanikana izvi Arctic Ocean anokurukura yePacific uye Atlantic.

mhenderekedzo yegungwa kwakasiyana zvakakwana simba kwetsinga. Sea Arctic Ocean kutora hafu yacho yose. Vanosvika vapfumbamwe. Chikuru chacho Norwegian, uye duku - Gungwa White. In mvura yakawanda chitsuwa archipelagos, uye pasina munhu zvitsuwa.

About hafu yacho yose pasi pasherufu dziparadzwe. Nemhenderekedzo Eurasia pasherefu ubvise kusiyaniswa rinokosha upamhi uye akafukidza nemazana mazhinji makiromita. The seafloor iri nembiya akawanda kuti bhadharwa nevanhu pasi pemvura anooneka zvikuru nemichinjiziri. The chikuru chezvinonhuwira pasi Tinozorodzwa kuonekwa musimboti Haeckel, iyo inopfuurira kuti Mid-Atlantic Ridge. Isolated uye Mendeleyev Simuka, Lomonosov, chukchi.

Arctic Ocean akapfuma placer deposits weheavy metal (stannous nevamwe). Emadhaka akaumba ari pasherefu nzvimbo rwizi sediments. It vakawanawo pamusoro mafuta uye gasi minda makumi mashanu, vamwe izvo kutanga kugadzirwa.

Polar nzvimbo kuti zvinotora kweArctic Ocean, ane simba pamusoro hunhu waro okunze. Pamusoro pemvura vakaumba uye vakatonga rose gore peArctic mhepo guru. In yechando, avhareji tembiricha mhepo iri akatura kuna mana madhigirii, mwero iri pedyo razero muzhizha. Panguva yacho polar zuva, nokuda mano echando kunoratidza vazhinji zuva nemwaranzi, okunze anova zvikuru. Uwandu kunayisa chinozova pamusoro penyanza mugore, kubvira zana mazana maviri millimeters.

In kweArctic Ocean ine hova simba zvakakwana nemvura inodziya. Kutamira kumabvazuva uye nechokuchamhembe, zvikuru gobvu uye wakawanda mvura inodziya anyatsofukidzwa pasi kudaro wakawanda, asi mvura inotonhora. Rwizi Ichi chikamu North Atlantic Current. Transarctic kuyerera anoita Atlantic kuburikidza muDenmark Strait chando mvura uye polar. Bato iri rinotungamirirwa kubva kumabvazuva kusvikira kumavirira, kubva East Siberian uye Sea chukchi.

The raivapo hydrological hurumende uye upenyu mugungwa iri nekugadzirwa kupisa uye mvura exchange akapoteredza munyanza. Mvura makore kuramba dziripo kupisa chinotsigirwa Atlantic mvura inflow. It anowedzera tembiricha uye akazoita salinity pa- eko kubva munharaunda yose North America uye Eurasia. Panguva yakawanda pamusoro mvura, tembiricha yakaderera uye ari pedyo nechando pfungwa (kana iripo salinity), vanoumba mumwe kubvisa maviri inegumi. Muzhizha tembiricha inokwira kusvika mashanu sere madhigirii kupfuura razero chete Sub-peArctic latitudes.

Ice chiripo gore rose. Izvi hunhu Oceanic hunhu. The inonyanya rongedza - Ice-gore Multi, ane ukobvu - kubva maviri mana metres uye zvakawanda. Munguva yechando kugadzirazve chando kupfuura Unonyunguduka muzhizha; surpluses akatakurwa vakapinda Atlantic Ocean.

Panobva kurema zvipenyu mvura chinosanganisira inotonhorera nemishonga diatoms. Ivo yakatekeshera zvose pamusoro chando uye mumvura. Mune Atlantic mudunhu kupararira phytoplankton uye zooplankton, benthic algae ikoko. Mumakungwa uye makungwa kurarama zvokutengeserana mhando hove (halibut, safuroni cod, cod, etc.). Pakati mhuka dzinowanzotaurwa walruses, polar mabheya, nemicherechedzo, beluga.
