Kuyini isiqhingi? Sakhiwo izinyathelo ukwakha

Igama elithi "isiqhingi" okungenani kanye empilweni yami wezwa wonke umuntu. Kwathi kithi ezivela olimini Maldivian. Ungathanda silazi kangcono lo mqondo futhi uthole ukuthi yini isiqhingi esikhulu? Khona-ke asiqale incazelo emfushane.

Thina ukuchaza umqondo

Atoll ngokuthi isiqhingi coral, okuyinto efana embuthanweni ngokugcwele noma ephukile. Ngaphakathi kuba ichibi ukuthi kuyinto samanzi ezincane, okuyinto uyashiywa kolwandle noma olwandle Amanzi isiqeshana ewumngcingo ugu. Incazelo ngokunembe kakhudlwana lokho isiqhingi - kokuphakama ekuphumeni kusukela ekujuleni kolwandle, eyasungulwa superstructure coral. Emanzini angajulile, izixhobo zama-coral namaqembu uhlobo iziqhingi, phakathi okuyinto kunamavesi. Ngezindleko zabo ichibi okuxhunywana olwandle. Kodwa uma kwakhiwa isiqhingi is njengoba indandatho avaliwe, amanzi echwebeni abe usawoti ngaphansana olwandle ezizungezile. Babevame akhiwa mlilo yokuqothulwa. Meaning of igama elithi "Atoll" zingatholakala kunoma yisiphi isichazamazwi.

Sakhiwo izinyathelo ukwakha isiqhingi

Izigaba lokuqala kumiswa ezingamaqoqo wazama ukuchaza Darwin. Esikhathini esizayo, imibono kubo kwaqinisekiswa ngokubukisisa eziningi lososayensi yesimanje.

Ngo esigabeni sokuqala ekujuleni kolwandle iqala ukwenza intabamlilo. isiqhingi Volcanic ukwanda ambalwa ngaphezu kolwandle. Slope kancane kancane yene coral, kanye intabamlilo ngokwayo kancane ocwilayo. Ngaphambi polyp koloni ifinyelela ebusweni, sidlule isikhathi eside. Iningi ezingamaqoqo lanamuhla kwakhiwa emva Ubudala Ice. Ukuze lokhu inhlangano yavalwa indandatho umumo, futhi ukucwiliswa intabamlilo ukwanda coral okufanele uhambe ngayo cishe ngezinga elifanayo, kungenjalo iringi ngeke ingadabuki.

Nokho, ukucwiliswa in kolwandle izintaba-mlilo ngeke kwenzeke Kulokhu uhlala ngaphakathi esiqhingini ichibi wentaba-mlilo. ukwakheka okunjalo kwezinkolo kubizwa ngokuthi ambalwa nolaka - yenuzi isiqhingi. Islands ezakhiwe kwamakhorali amakoloni, kungenziwa isethwe.

isiqhingi ngalinye has 3 izingxenye:

• yangaphandle zamakhorali emthambekeni;
• obukhulu platform zamakhorali;
• maphakathi nezwe emanzini, okungukuthi echwebeni.

Ukuphakama isilinganiso akuvamile idlula 4 amamitha ngaphezu kolwandle, kodwa endaweni zokwakheka ezifana kungaba ngempela eliphezulu. Ngakho, isiqhingi esikhulu kunazo zonke emhlabeni ubhekwa Kwajalein, okuyinto likhona leziqhingi of eMarshall Islands. endaweni yayo - engaphezu kuka-2,300 amakhilomitha square. Kodwa ku-92% walesi ndawo kuhlala echwebeni. Futhi okuwukuphela kwakhe kulesi siqhingi ezweni mayelana 15 amakhilomitha square.

Ukwakha izinto ze-izixhobo zamakhorali

Usuvele nibone ukuthi isiqhingi? Futhi kubonakala sengathi ngeziningi zezinto zokwakha kuyiphi zamakhorali zakhiwa? polyp Coral ikilasi ka ezilwane ezingenamgogodla benthic eziphilayo. I izixhobo isakhiwo abathintekayo izinhlobo polyp, okuyinto abe skeleton calcareous. Ngokuvamile, izixhobo yakhiwa yamakhorali Stony nezinhlobo eziningana ulwelwe ukuthi bayakwazi ukukhulula lime emanzini ezizungezile. Beka imfundo izixhobo zama-coral - amanzi angajulile kwezilwandle ezishisayo. Iningi lazo zitholakala kule-Indian nasePacific Ocean Ocean.

Inkinga ikuphi-ingabe amanzi ahlanzekile? Njengoba uhlaza khona?

Ukwazi ukuthi lokhu isiqhingi, abaningi bayazibuza ukuthi umsuka amanzi ahlanzekile futhi izimila iziqhingi coral. Imifula, imifudlana, kanye neminye imithombo amanzi okuphuza ahlanzekile in eziqhingini, kodwa akaphumelelanga akulona icala. amanzi ahlanzekile, iza lapha kuphela ngesimo imvula.

Waves okugaya njengoba giant ingxenye nepepper eqina nezixhobo isihlabathi ungqimba imali phezu isiqhingi. Kulesi ukuxubana ukuza imbewu ezitshalweni nasezihlahleni ezihlukahlukene linesizotha. Ngokuvamile ziqhume alethwe Ocean ukhukhunathi. Kancane kancane limestone amawa embozwe amasundu nezihlahla. Ngokuvamile, izilwane Atoll khona, kodwa kukhona okunhlobonhlobo izinambuzane. Futhi engxenyeni yolwandle oluzungeze wathola eziningi izinhlanzi.
