The Ocean Arctic

The Ocean Arctic lili Arctic, mu gawo wofunika. dziko momuzungulira pafupifupi kuchokera kumbali zonse. Makamaka Mzimuyo ndi makhalidwe a chilengedwe zachilengedwe: nyengo zinthu hydrological. The Ocean Arctic ndi laling'ono kwambiri pa nyanja zonse padziko lapansili.

Border madzi kugona ndi Scandinavia Peninsula ku Faroe ndi Mahatchi Islands, mu Nyanja Bering, ndi Davis Khwalala, ndi Denmark. Kudzera m'mavuto izi Arctic Ocean amalankhulira ndi Pacific ndi Atlantic.

mwanyanja losiyana mokwanira amphamvu kung'ambika. Nyanja Arctic Ocean zatenga hafu ya dera lonse. A okwana asanu ndi anayi. Yaikulu ndi Norway, ndi laling'ono - Nyanja White. M'madzi zambiri archipelagos chilumba, ndi osadalira pa zilumba payekha.

Pafupifupi theka la dera lonse la alumali pansi m'tsogolo. Gombe la Europe ndi ku Asia alumali Mzere kusiyana ndi kupingasa wapadera ndi maulendo ambiri makilomita. The seafloor ndi mabeseni osiyanasiyana omwe alinso ndi zitunda m'madzi. Waukulu chigawo chimodzi cha mpumulo pansi imatengedwa kuti maziko a Haeckel, omwe akupitiriza kwa Mid-Atlantic Ridge. Wakutali Mendeleyev Rise, Lomonosov, Chukchi.

Arctic Ocean wolemera placer miyala ya heavy (stannous ndi ena). Chitayiko kupangidwa mu alumali m'dera m'dambo mtsinje. Komanso wopezeka mafuta ndi gasi minda makumi asanu, ena amene ayamba kuphunzira.

malo kumalo ozizira kuti zimatengera Ocean Arctic, ndi mbali yaikulu pa makhalidwe a nyengo yake. Pamadzi zinapangidwa chogwidwa mu chaka misa kozizira mpweya. M'nyengo yozizira, pafupifupi kutentha mpweya adatchithisira digiri makumi anai, mlingo ali pafupi ziro m'chilimwe. Pa tsiku kumalo ozizira, chifukwa cha luso ayezi umalimbikitsa kwambiri cheza dzuwa, nyengo amakhala kwambiri. Kuchuluka kwa mpweya imene imagwera pa nyanja pa chaka, kuyambira zana kuti millimeters mazana awiri.

Mu Ocean Arctic imakhala yamphamvu mtsinje chokwanira cha madzi ofunda. Kupita kum'mawa ndi kumpoto kwambiri wandiweyani ndi mchere madzi ofunda adalowetsedwa pansi si choncho amchere, koma madzi ozizira. mtsinje ndi gawo la North Atlantic Current. Transarctic otaya zimapangitsa Atlantic kudzera Denmark Khwalala ayezi madzi ndi kumalo ozizira. Kupita imatsogoleredwa kuchokera kummawa mpaka kumadzulo, kuchokera East Siberia ndi Chukchi Sea.

Alipo hydrological boma ndi moyo m'nyanja anakhalabe ndi kutentha ndi madzi kuwombola ndi nyanja ozungulira. Unyinji madzi zonse kotunga kutentha imayendetsedwa ndi Atlantic madzi inflow. Izo kumawonjezera kutentha ndipo kumachepetsa amenewa a runoff kwambiri ku dera la North America Europe ndi ku Asia. Pa zambiri za madzi pamwamba, kutentha otsika ndipo ali pafupi kufika yozizira koopsa (pamene zilipo amenewa), apanga madigiri wina opanda awiri. M'chilimwe kutentha limatuluka digiri zisanu mpaka eyiti pamwamba ziro okha M'madera a zitunda boma kozizira.

Ice alipo chaka chonse. Izi ndi khalidwe la chikhalidwe zikuluzikulu. Ambiri paketi - Mipikisano chaka ayezi, amene makulidwe - kuchokera mamita awiri kapena anayi ndi zambiri. M'nyengo yozizira kubala ayezi kuposa chimasungunula pa dzinja; surpluses ikuchitika mu Atlantic Ocean.

Maziko kulemera kwa madzi kwachilengedwenso tichipeza ozizira zosagwira diatoms. Iwo ali wamba onse pa ayezi ndi madzi. M'dera Atlantic ya kufala kwa timayandama ndi zooplankton, benthic algae kumeneko. Nyanja ndi nyanja moyo mitundu malonda a nsomba (nsomba yam'nyanja yamchere, duwa m'nyanja zikuluzikulu m'nyanja zikuluzikulu, etc.). Mwa nyama ndi walruses wamba, zimbalangondo, zisindikizo, beluga.
