Ngenxa yokuba le lexinene lomkhenkce yi malunga ne-10% ngaphantsi kwe le lexinene amanzi, ukuba isambuku yomkhenkce (90%) alele ezantsi komhlaba ngamanzi.

Apho kwakheka kwazo

Xa ikhweyitha osemantla indawo yokuzalwa eGreenland esoloko babize ice ezikroziswayo, ukususela kumaxesha ngamaxesha ekuthumeleni okungeyomfuneko Atlantic Ocean. Phantsi yempembelelo imisinga kunye neebhloko yimimoya ice ithunyelwa kwelasezantsi icala, ngasezantsi, ukunqumla yemizila elwandle adibanayo North nakuMzantsi Melika ukuya eYurophu. Ubude yohambo lwabo ezahlukeneyo ngamaxesha ahlukileyo. Entwasahlobo, kodwa musa ukufikelela ukuya 50º nayo. m., kwaye ukuwa unako ukufikelela 40º kunye. w. Kule kBude imizila transoceanic.

Yomkhenkce - block lomkhenkce ukuba ube kufuphi nonxweme Antarctica. Ukusuka kule ndawo uqalisa indlela yayo eya novalo the Pacific, Atlantic namaLwandlekazi Indian. Le mimandla azikho zifunwa phakathi keli kuba indlela yabo engundoqo kokudlula kwi iPanama Suez Imijelo. Noko ke, ubukhulu kwazo kunye nenombolo yabo kunathi nezibonisi kumntla ikhweyitha.

umqobo berg

Ukwazi oko yomkhenkce, siya kuqwalasela esiXhoseni. floes ice Tabular - isiphumo inkqubo ukukha iindawo ezinkulu ice ezishelifini. isakhiwo yabo inokuba nomahluko kakhulu ukusuka firn ukuya ice glacier. Ezona mpawu umbala abangazaziyo ukuba isesisiqalo. Ingca isisihla has a matte entanjeni emhlophe ngenxa inani elikhulu zezulu kule nwebu zangaphandle ikhephu ubunjwe. Ekuhambeni kwexesha, irhasi asuswa kunye phantsi amathontsi amanzi, ngenxa yokuba yintoni yomkhenkce ipeyintiweyo ngombala oluhlaza okwesibhakabhaka.

yomkhenkce Tabular - oku ibloko eqinileyo kakhulu ngumkhenkce. Enye abameli ezinkulu zalo Uhlobo le imilinganiso ka 385 × 111 km. Omnye waba indawo irekhodi malunga 7 amawaka. ^Km2. Imali ezisisiseko kwazo tabular na imiyalelo sezingeni ngaphantsi kwe kulawo aboniswe. ubude sabo malunga 580 m, ukuphakama phezu kwamanzi -. 28 m phezu ukuba abunjwe ngayo eminye imifula kunye namachibi ngamanzi zaphela.

enkulu pyramidal

yomkhenkce Pyramidal - oku kubangelwa ice landslides. Bona azakubalulwa kwincam kunye isiphelo esibukhali kwaye umphakamo omkhulu ngaphezu phezu kwamanzi. Ubude iibhloko ice olu hlobo malunga 130 m kunye ukuphakama inxalenye kumphezulu -. 54 m umbala wabo olwahlukileyo soft namona tabular ezibuhlazarha-oluhlaza, kodwa esisigxina kunye kwazo mnyama. Kule ice kukho ukubandakanywa ebonakalayo yamatye, isanti okanye intlenga, leyo zifakwa kuyo ngexesha intshukumo siqithi okanye nezwe.

Usongo imikhumbi

Eyona eyingozi ke kwazo ukuba kwi North Atlantic. qho ngonyaka olwandle busisigxina ku-18 amawaka. ice swingers New. Baziphawule kuphela kumgama akukho ngaphezu kwesiqingatha sekhilomitha. Akwanelanga ukuba ixesha bajikise okanye ukunqanda inqanawa ukunqanda ukungquzulana. Le peculiarity kula manzi kukuba abantu basoloko quba, nalapho ixesha elide akuthethi uthothe.

Oomatiloshe eziqhelekileyo kunye nentsingiselo eyoyikekayo elithi "enkulu". Eyona eyingozi ke floes ice omdala, ezithi kunyibilike ungaphinda kwaye phantse musani ezivelileyo ngaphezu kolwandle. "I-International Ice okhuselo" ihlelwa 1913. abasebenzi zakhe nakunxibelelwano ngeenqanawa kunye moya, ukuqokelela ulwazi malunga kwazo kunye zilumkisa ingozi. Qikelela intshukumo ice swinger phantse nzima. Asebenza kwimo ngokuzenzekela, ukubenza kwazo zibonakale ngakumbi ziphawulwe ngepeyinti eqaqambileyo okanye CTLI.
