Siqithi Tropical coral - ukubunjwa eziphilayo

Xa ukwazi yesiqhelo siqithi - yinto indawo yomhlaba, engqongwe ngamanzi macala onke. Eli gama libhekisela kwiindawo zinobukhulu komhlaba, umzekelo, Iceland, kwaye imvuthuluka ezincinane esibhakabhakeni ethile phezu komlambo, apho unyamalale ngokupheleleyo konogumbe. Ngu neziqithi zayo imvelaphi kunokuba nemisinga (adalwe yi nokuhamba ziitectonic plates), mlilo (ezivela ngenxa mlilo mlilo) namytye (imihlaba enesanti leyo kwasekwa ukusuka qhina), iziqithi neekorale ezininzi elibe lenziwe, ekugqibeleni cell. Ukuba amaqela emine yokuqala, kucacile ukuba lo ngenxa yeenkqubo zendalo zomhlaba okanye umsebenzi yabantu, yintoni ebandakanyekileyo ekubunjweni siqithi neekorale, kuba siyazi ukuba coral - omzimba ophilayo?

Xa amanzi ashushu kweelwandle yetropika zihlala ezi zidalwa abangekaphuhli luthintithayo zitya kwizidalwa, wambamba Mpondwana zabo. silwanyana ngasinye kwakha kuye indebe lekalika. Ekugqibeleni iyithyubu uyafa yaye indebe ihleli. Ngenxa yokuba liqhubu yayo entsha yakha lekalika ngokwawo yokuhlala. Kunye amathanga coral bekhula, ngokungxama ngenxa ezincinane ukuya ilanga de bafikelele kumgangatho wolwandle akayi kuvuka ngaphezu komhlaba. Oku kwenza isiqithi izixhobo.

Kungokwemvelo ukuba sicinge ukuba eli - iziqithi phantsi, njengoko coral - nezilwanyana zaselwandle, yaye bayasweleka phezu komhlaba. Ubunzulu kangangoko kubo - malunga 30-10 eemitha, apho izaqhwithi uziva kwaye ngexesha elinye kwelanga ngokwaneleyo. Kutheni, ke ngoko, ebomini, isiqithi izixhobo unokufikelela ubude amakhulu ambalwa eemitha? Ewe, ngenxa yokuba i ziitectonic plates kuzinambuzane rhoqo umhlaba. Ukuhla nokunyuka kwinqanaba kwintsele yolwandle kungazisa i emanzini phezulu okanye niyibeke kummandla yobumnyama obungunaphakade, xa iimitha 200-300. Kucacile ukuba ngokuhamba kwexesha isiqithi sublime ligutyungelwe lomhlaba kunye nezityalo, kodwa zisekelwe uya wakhiwe amathambo yilimestone abaninzi polyp elide-efile.

Coral Island unokuba iindidi ezimbini: siqithi kanye, ukuba uqhelene kuthi hlobo indawo ngaphezu komphakamo wolwandle ngokohlobo zeengxondorha, kunye iRose. Yintoni akaphumelelanga kwaye akhiwa njani? Intle elula, nangona ixesha elide. Akaphumelelanga ukuba kakhulu kwi Pacific Ocean, apho, njengokuba usazi, umsebenzi onamandla kunene mlilo. Khawucinge i siqithi, nto leyo liphakanyiswe ngaphezu mlilo kwamanzi kuyo. Xa noseko lwalo, emanzini, hayi kuphela afudunyezwe lilanga, kodwa ukubilisa daka enkolontyweni, ungathanda ukulungisa polyp. Baya kwakha coral ehlabathini siqithi, Belting ngathi ngomsesane. Koko, emva kwenkulungwane lomsebenzi neekorale, intaba-mlilo kwenzeka kunye entabeni ... liqhuma ubalekela endaweni amanzi enzonzobila. Kodwa angangenwa! Nge moya iRose elivelayo ijikelezwe umsesane blue elwandle, ngaphakathi yazo ichibi eluhlaza - bonke abaseleyo mlilo kanye loyikekayo.

Kakade ke, akusoloko mlilo etshona elwandle, kwaye iziqithi mlilo nekorale kakhulu rhoqo. Imizekelo yalo sibona e Tonga karhulumente bio-ukubona ngokuncedisana (Polynesia), nto leyo Sisihloko iziqithi mlilo engqongwe coral, ezabo. Umzekelo wezinto iRose ukuba imilo ring phantse idelno yi bra.

Coral Island - le nkqubo. Kunokuthiwa ukuba izixhobo zezona kunezizwana zonke zokuhlala zaselwandle. Zange sisehla sibengaphantsi lobushushu amanzi degrees-20, indawo yokuhlala Izakufunyanwa wendlela nekorale, nemiqolomba kunye namatyholo, nobuninzi ukutya ngoka iintlobo ezininzi zezidalwa. Polyp kudliwe ezincinane, yaye, bona, ezindidlayo ezimibalabala isikhwenene intlanzi, ibhabhathane intlanzi, kwakunye ezizinkwenkwezi ukuzibambela "isithsaba sameva". Emathambekeni zama ukulungisa urchins elwandle , kunye anemones ulwandle. Kwabaxhamla iigadi coral amfipriony yokusabela encinane eyaziwa kuthi yi khathuni "Nemo intlanzi", yaye emiqolombeni yamawa nasemingxunyeni neekorale abafileyo balindelwe eels zabo ixhoba. Ngelishwa, ngenxa yobundlobongela yabantu umsebenzi sixhobo kukufumana ezincinci, kuba polyp bahlala kuphela ngamanzi acocekileyo kakhulu. Ochukumisa coral kunokukhokelela ekufeni kwakhe. Ngoko ke, njengokuba kumazwe afumileyo, zange anganyathela polyp, yaye ngakumbi ungazaphuli amasebe coral-ethe.
