Amanzi ayinto ebaluleke kakhulu yemvelo emhlabeni, yonke imijikelezo yemvelo nezinqubo zemvelo kuncike kuyo. Siyaqonda ukuthi amanzi akha ngaphezu kwe-70% yomhlaba oyiplanethi, ihlinzeka zonke izidingo womuntu ophuma emanzini, ngokuzilibazisa nokuhlanza.
Ukugcina izindawo ezi-100% ezilungile zasemanzini akuyona indaba yecebo lokumaketha ukuze udle imikhiqizo eminingi yemvelo, kepha, ukuze impilo enokuqonda okuningi ngelungelo lokuphila ngamanzi okuphuza asezingeni eliphakeme futhi uhlala nezindawo zemvelo ezingenakho ukungcola. Ngalokhu nokuningi, kufanele wazi ukuthi iziphi izizinda zamanzi eziyinhloko, yiziphi izimo zazo nesizathu salezi zinqubo.
Amaphesenti wamanzi emhlabeni
Ngaphambi kokuphenya kabanzi ngezindawo ezahlukahlukene zamanzi, kubalulekile ukwazi ukuthi le nto yemvelo enama-athomu amabili e-hydrogen ne-athomu eyodwa yomoya-mpilo inamaphesenti amaningi eplanethi yomhlaba.
Ngokunemba, Ama-97% wamanzi omhlaba atholakala olwandle kanti ama-70% aqukethe amachibi, imifula nezinye izindawo zamanzi ahlanzekile; okwenza kube yinto ebaluleke kakhulu embulungeni yonke. Kuphela ngama-29% eplanethi aqukethe ubukhulu bamazwekazi.
Ngakolunye uhlangothi, u-69% wamanzi ahlanzekile angaphansi kwezigxobo, okusho ukuthi iqandisiwe, uma amanzi ethi uzoncibilika, ulwandle luzokwanda amakhilomitha bese kuba nezinxushunxushu zemvelo.
Kungaleso sikhathi lapho amanzi amboza ama-70% womhlaba, kepha aqukethe kuphela u-0,02% wesisindo esiphelele seplanethi yomhlaba.
Ziyini izifunda zamanzi?
Ukubuyela kusizathu sokuba yilokhu ucwaningo lwesayensiSingasho ukuthi amanzi anezifundazwe ezintathu eziyinhloko: isimo esiqinile, isimo esiwuketshezi nombuso onegesi.
Isimo esiqinile
Lapho amanzi ihlangana namazinga okushisa ayi-0 ° noma ngaphansi, iyaqina kungakhathalekile indawo ezungezile. Ishiya isithombe esingaqondakali, iba yinto engokomfanekiso enobukhulu futhi ekwazi ukuchazwa ngokubonakalayo; Lokhu kwenzeka ngenxa yamandla amakhulu izinhlayiya okufanele zihlale ndawonye lapho ziqina: kuhlanganiswa, amandla akhangayo adalwa phakathi kwezinhlayiya.
Ngokungafani nezinye izinto eziwuketshezi, amanzi, lapho efinyelela esimweni sawo esiqinile, okungukuthi, lapho efriziwe, angakhuphula isisindo sawo. Yingakho uma ubamba isitsha ngamanzi, sizokwandisa ubukhulu baso. kubanda ngaphandle kwemingcele yalesi sitsha. Amanzi aqinile angahlala ngaphandle kwezinkinga emanzini angamanzi, lokhu kuchaza ukuthi izinhlanzi nezinye izilwane zasolwandle ezivela emazingeni okushisa abandayo zingabhukuda kanjani ngaphansi kwezinguzunga zeqhwa. Ngokusobala, isimo esiqinile samanzi singatholakala kuphela ezigxotsheni zeplanethi yomhlaba noma, uma kwehluleka lokho, emazweni asondelene nabo: isibonelo: Canada.
Isimo samanzi
Lokhu kwenzeka lapho amanzi ehlala emazingeni okushisa aphakathi kuka-0 ° kuya ku-100 °. Lona umkhawulo ojwayelekile izinga lokushisa lapho kungenziwa khona amanzi ngaphandle kwezinkinga.
Kuyisimo esivame kakhulu sale nto, abantu neplanethi yomhlaba bayondliwa yiyo. Okubandakanya imifula, amachibi nolwandle, amanzi asesimweni soketshezi ayadingeka kakhulu kwi-ecosystem.
Asebenza kaningi emhlabeni wezinto zamakhemikhali, amanzi angaba yisixazululo esilula seminye imikhiqizo, ngaphandle kwezinto ezinamafutha. Ngaphezu kwalokho, isebenza njengendawo yokuxhumana Phakathi kwezilwane zasolwandle, ngenxa yamandla azo omsindo, ama-cetacean nezinye izilwane zasemanzini zingadlulisa umyalezo ngama-wavelengths.
Isimo seGaseous
Lesi sifundazwe asinawo umumo noma ivolumu ethize, simane sinezikhala ezithile esitsheni noma imvelo oyihogelayo. Izinzuzo zomjikelezo we-hydrogen ngalesi simo segesi ngoba kwenziwa ngaso.
Izinga lokushisa eliguqulela amanzi esimweni salo segesi yikho konke okubandakanya u-100 ° noma ngaphezulu. Isibonelo, umhwamuko wamanzi, udlula emoyeni uze ube yifu ngenxa yobuningi bezinhlayiya eziqoqiwe, okuzodala ukuthi imvula ihlale futhi ngesimo semvula ukuqedela umjikelezo wokuphila wazo zonke izidalwa eziphilayo.
Yini egqugquzela ushintsho lwamanzi?
Umjikelezo wonke wemvelo oyiphindwa yiplanethi yomhlaba kusuka lapho uvela khona. Kubukeka sengathi konke kuyingxenye yemvelo okuyiyo nje. Ngenxa yezinguquko ezahlukahlukene zesimo sezulu ezilethwa yiplanethi ngonyaka, umjikelezo wayo ozophindaphindwa minyaka yonke, amanzi angafeza ukuguquka kwawo ezifundazweni zawo ezintathu.
Ukushintshwa njalo kwezimo umuntu noma izilwane zasendle eziguqukayo kwenza izikhala ziqukethe isimo sezulu esihlukile isikhathi ngasinye, okuzokwenza inqubo ye-hydrogen nokusetshenziswa kwezinye izifunda zamanzi kube umjikelezo njalo njalo.
U-Elixir Wonkulunkulu
Umuntu uhlale ekuthokozela lokho angenakho, efuna ukuyeka ukuba nalokhu anakho. Amanzi ahlanzekile aqukethe kuphela ingxenye encane yabantu emhlabeni, lapho kuthinteka khona amazwe afana nalawo akha izwekazi lase-Afrika nalapho kugcwele khona amanzi anosawoti nezinsiza eziyivelakancane zokuwahlanza.
Kuyindaba yokufunda ukubonga ngethuba elihle lokusebenzisa amanzi ahlanzekile nsuku zonke, sicabanga ukuthi abantu abakwazi ukufinyelela kulesi sidingo esiyisisekelo.
Ukukhankasela nokwakha amasu ezemfundo ahlobene nokugcinwa kwezikhala zemvelo kanye nokuvinjelwa kokungcola kwemvelo; kuyisinyathelo esihle sokuqeda imininingwane eyiphutha ekhona ngalolu daba.
Ngalokho, qinisekisa ukuthi ohulumeni badlala indima yokugcina izinhlelo zokuhlanza amanzi lokho esikudlayo kungenye yamalungelo okufanele sonke isakhamuzi sisebenzise; ikakhulu emazweni angenawo umthombo ozinzile wamanzi okuphuza ngoba amanzi anosawoti abusa kakhulu.
Ukuyicabangela nokuyihlonipha njengesithako sonkulunkulu, kuzokwenza izizukulwane ezintsha zikwazise ukubaluleka kwangempela kokusebenzisa amanzi amsulwa nokuhlala endaweni ehlanzeke kakhudlwana.
