Pacific Ocean - Geography Mfundo ndi Ziwerengero

Pacific Ocean - waukulu mwa nyanja za padziko lathuli. Malo ndi nyanja onse ndi miliyoni 178,6 mamita lalikulu. makilomita, avareji akuya mamita 3980, voliyumu ya madzi - kiyubiki mamita miliyoni 710. makilomita. Pamafunika za 40% ya dziko lapansili ndi pafupifupi theka la malo ake madzi. Choncho, dzina lenileni "Wamkulu", ndi Spanish wofufuza Vasco de A Balboa mu 1513, ali ndi zifukwa zomveka.

Malinga ndi chiwerengero cha zilumba nyanja chimphona limanenanso Kanjedza. chiwerengero chawo - 10 zikwi, chiwerengero m'dera - pafupifupi mamiliyoni 3.6 mamita lalikulu. makilomita. Kumpoto ndi za Aleutian Islands, kumadzulo - Sakhalin, ndi Kuril Islands Japanese ndi Chifilipino, Tasmania, New Zealand ku New Guinea, Small ndi Wamkulu Sunda Islands. Mu chapakati ndi kum'mwera m'madera a nyanja achuluka zilumba ang'ono ndi archipelagos.

Mafunde a Pacific Ocean anawagawa ofunda (North Pacific, Alaska, Kuroshio - kumpoto kwa East Australia, South Equatorial - kum'mwera) ndi kuzizira (Peru ndi kumadzulo mphepo ya kum'mwera Kuril ndi California mu kumpoto). Madzi kutentha pa equator - za 27-28 ° C, mu zigawo kumalo ozizira - za 0 ° C.

The kumalo ya Pacific Ocean , pamodzi ndi nyanja ndi m'mavuto zatenga oposa 30 miliyoni sq M.. makilomita, lomwe ndi 18% ya malo ake. Ambiri mwa Nyanja ili m'mbali kugombe la Europe ndi ku Asia (Bering Nyanja, nyanja ya Japan, nyanja ya Okhotsk ndi zina zotero.), M'mphepete Australia, ndi chilumba kusamba ndi Asia South-East. Gombe la Antarctica ili Amundsen Nyanja, Ross ndi Bellingshausen.

The kumalo yaikulu ya Pacific (Alaska, California ndipo Panama), amatsuka kugombe la America.

Masamba dziko nyanja kwake zosiyanasiyana makamaka osaya pamodzi m'malire a zilumba ndi moti matanthwe. Chiwerengero chachikulu wambiri M'madera a zitunda otentha ndi yamphamvu. Ocean zomera zikuphatikizapo mitundu yoposa 100,000 mogwirizana zosiyanasiyana nsomba mu kotentha kumene kuli zoposa 2000.

Chifukwa mmene lalikulu la Pacific Ocean amaphatikizapo mabacteria yosiyanasiyana nyengo. Ambiri lili kunyanja, otentha mabacteria ndi. Kufalitsa m'mlengalenga pamwamba nyanja kumabweretsa mphepo ndi mafunde, makamaka kum'mwera M'madera a zitunda kotentha. Mu dera la kumadzulo kwa nyanja chimphepo pafupipafupi. Kutentha kumadzulo ndi kum'mawa m'madera zingasiyane mu M'madera a zitunda womwewo wa ofala ulamuliro utuluke ofunda kapena ozizira.

Mu nyanja kumpoto Pacific lili ku Arctic, ndi amaundana madzi m'nyengo yozizira chifukwa otsika kutentha, namkholowa zimachitika. Mu nyanja ozizira mozungulira gombe la Antarctica, namkholowa kwaiye mafunde ndi mphepo anatengedwa ku danga lotseguka madzi.

Pacific kudutsa yaikulu nyanja ndi mpweya zodutsa yolumikiza m'mayiko amene Pacific beseni. Umadutsa ndi polumikizira zodutsa ku mayiko a ku Indian ndi Atlantic nyanja. Major mayiko madoko nyanja ili m'mphepete mwake. Izi Singapore, Sydney, Shanghai, Vancouver, Los Angeles, Vladivostok, Nakhodka. Theka la nsomba dziko nsomba amachokera ku Pacific gawo. Mitundu yofala masewera nsomba monga: hering'i, m'nyanja zikuluzikulu, nsomba, pollock, redfish. Komanso yotengedwa nkhanu, nkhono ndi shrimp.

"Border" 180th Meridian (malire tsiku kusintha) amadziwikanso ili m'gawo lake.
