Nyanja dziko

madzi Natural limabweretsa mbali yaikulu ya padziko Dziko Lapansi ndi nyanja za dziko ndi nyanja m'madzi zatenga za 97% (kapena pafupifupi 70% ya padziko lonse Lapansi). M'dera otsala wa madzi a mitsinje, nyanja, Madamu, zithaphwi, oundana.

Pacific, Atlantic, Arctic ndi Indian - nyanja dziko otchedwa asayansi mpaka 2000. Popeza 2000, kum'mwera kwa Arctic anali yekhayekha monga nyanja wachisanu.

Nyanja kuya ku dziko ndi yaikulu - Pacific. Iwo ali ndi lalikulu kuposa dziko dera lonse la dzikoli, koma mu kuya kwake ndi malo ovuta Padziko Lapansi - ndi Mariana ngalande. Ocean mafunde kusamba chakumadzulo kwa gombe la North ndi South America, Australia, kum'mawa gombe la Asia. Mu kumpoto kwa dziko lapansi kuti zikugwirizana ndi Ocean Arctic kudzera pa Bering Strait, ndi kum'mwera - umalandira gombe la Antarctica. Kwambiri zambiri gombe ndi akakhala a mapiri mtunda, ndi mwa madzi ake ndi ambiri zilumba.

Mwachibadwa, nyanja zonse za mdziko ndi khalidwe osiyana kwambiri. Choncho, tisaiwale kuti Pacific Ocean anatchuka chifukwa kusefukira kwa madzi pafupipafupi kuti akafike kugombe la ena mamita makumi asanu mu msinkhu, komanso chakuti chimachititsa oposa theka la zotsalira zazomera okwana kuya m'madzi.

Achiwiri kukula ndi Atlantic Ocean. pansi pake m'malo zovuta, ndi mabeseni angapo. Mosiyana ndi Pacific, Atlantic si madzi ake zilumba zambiri. Mu kumpoto likukwaniritsa Ocean Arctic.
