Amanzi yeyona nto ibaluleke kakhulu kwindalo esemhlabeni, yonke imijikelo yendalo kunye neenkqubo zendalo zixhomekeke kuwo. Siyaqonda ukuba amanzi enza ngaphezulu kwama-70% eplanethi yomhlaba, ibonelela ngazo zonke iimfuno Umntu ophuma kwi-hydration, ngokuzonwabisa kunye nokucoca.
Ukugcina indawo eyi-100% efanelekileyo yasemanzini ayisiyonto yesicwangciso sentengiso ukuze utye ngakumbi iimveliso zendalo, kodwa ke, ukuze ubomi obunolwazi ngakumbi kwilungelo lokuphila ngamanzi okusela asemgangathweni kunye nokuhlala kunye nendalo ngaphandle kokungcola. Kule nto nangaphezulu, kuya kufuneka uyazi ukuba zeziphi ezona ndawo ziphambili zamanzi, zithini iimeko zazo kunye nesizathu sale nkqubo.
Ipesenti yamanzi kwiplanethi yomhlaba
Phambi kokuphanda ngakumbi ngeendlela ezahlukeneyo zamanzi, kuyafuneka ukuba uqaphele ukuba le nto yendalo ineeathom ezimbini ze-hydrogen kunye neatom enye yeoksijini inepesenti enkulu yomhlaba.
Ngokuchaneka, I-97% yamanzi omhlaba ifumaneka elwandle kwaye i-70% inamachibi, imilambo kunye nezinye iindawo zamanzi acocekileyo; eyenza ukuba ibe yeyona nto ibaluleke kakhulu kwihlabathi liphela. Kuphela ngama-29% eplanethi aquka ubunzima bamazwekazi.
Kwelinye icala, i-69% yamanzi acocekileyo yeepali, oko kuthetha ukuba ngumkhenkce, ukuba amanzi athe anyibilika, iilwandle ziya kunyuka ngeekhilomitha kwaye kuya kubakho isiphithiphithi sendalo.
Kulapho ke amanzi agubungela iipesenti ezingama-70 zomhlaba, kodwa aquka kuphela i-0,02% yobunzima beplanethi yomhlaba.
Zithini iimeko zamanzi?
Ukubuyela kwisizathu sokuba yile uphando lwezenzululwaziSingatsho ukuba amanzi aneendawo ezintathu eziphambili: imeko eqinileyo, imeko engamanzi kunye negaseous state.
Isimo esiqinileyo
Xa amanzi Ukudibana namaqondo obushushu ka-0 ° okanye ngaphantsi, iyomelela ngaphandle kwendawo ejikelezileyo. Ukushiya ngasemva kwesithambiso esingaqondakaliyo, iba yinto yokomfuziselo enemilinganiselo kwaye inakho ukucaciswa ngokubonakalayo; Oku kwenzeka ngenxa yamandla amakhulu ekufuneka amasuntswana ahlale kunye xa omelele: ngokudibanisa, amandla anomtsalane ayenziwa phakathi kwamasuntswana.
Ngokungafaniyo nezinye izinto ezingamanzi, amanzi, xa efikelela kwimeko yawo eqinileyo, oko kukuthi, xa efriziwe, angonyusa ubunzima bawo. Kungenxa yoko le nto ukuba umisa isitya ngamanzi, siya kuyonyusa ubukhulu bayo. kubanda ngaphandle kwemida yesikhongozeli esitshoyo. Amanzi aqinileyo anokuhlala ngaphandle kwengxaki kumanzi alulwelo, oku kuchaza indlela iintlanzi kunye nezinye izilwanyana zaselwandle ezivela kubanda obushushu ezinokudada phantsi komkhenkce. Ngokucacileyo, imeko eqinileyo yamanzi inokufumaneka kuphela kwiipali zomhlaba okanye, ukusilela oko, kumazwe asondeleyo kubo: umzekelo: Canada.
Urhulumente wotywala
Oku kwenzeka xa amanzi ehlala kumaqondo obushushu aphakathi kwe-0 ° ukuya kwi-100 °. Lo ngumda osemgangathweni ubushushu apho amanzi anokufakwa khona ngaphandle kweengxaki.
Yeyona meko ixhaphakileyo yale nto, abantu kunye neplanethi yomhlaba bayondliwa yiyo. Amanzi aqulathe imilambo, amachibi kunye neelwandle, amanzi kwindawo engamanzi ayimfuneko kakhulu kwindalo.
Yenziwe kaninzi kwihlabathi lezinto zamachiza, amanzi anokuba sisinyibilikisi esilula kwezinye iimveliso, ngaphandle kwezinto ezinamafutha. Ukwengeza, isebenza njengonxibelelwano Phakathi kwezilwanyana zaselwandle, ngenxa yesandi sayo, ii-cetaceans kunye nezinye izilwanyana zasemanzini zinokudlulisa umyalezo ngobude bamaza.
Urhulumente weGaseous
Eli lizwe alinabume okanye ivolumu ethile, limane linendawo ethile kwisitya okanye nendawo ophefumlayo kuyo. Izibonelelo zomjikelo wehydrogen yile gaseous state kuba kungenxa yayo ukuba iyenziwa.
Iqondo lobushushu eliguqula amanzi libe yindawo yalo engumoya kuko konke oko kubandakanya i-100 ° okanye nangaphezulu. Umzekelo, umphunga wamanzi, udlula emoyeni de ube lilifu ngenxa yobuninzi beengqokelela zeengqokelela, eziya kuthi zibangele imvula iphinde ibuye emhlabeni ikwimo yemvula ukugqibezela umjikelo wobomi wazo zonke izinto eziphilayo.
Yintoni ebangela utshintsho lwamanzi?
Umjikelo wendalo uphela emhlabeni owuphindayo kwimvelaphi yawo. Kubonakala ngathi yonke into iyinxalenye yendalo ekulula ukuba yiyo. Enkosi kutshintsho lwemozulu olwavezwa yiplanethi ngonyaka, onomjikelo oza kuphindwa rhoqo ngonyaka, Amanzi anokuzalisekisa inguqu yawo kumazwe amathathu.
Kwangelo xesha, utshintsho olwenzeka rhoqo kwindalo apho umntu okanye izilwanyana zasendle ziguqula zenza ukuba izithuba ziqulathe imozulu eyahlukileyo ngalo lonke ixesha, eya kwenza inkqubo yehydrogen kunye nokusetyenziswa kwamanye amazwe amanzi abe ngumjikelo ngamnye kwaye rhoqo ngakumbi.
U-Elixir woothixo
Umntu usoloko ekuxabisile angenako, efuna ukuyeka ukuba nezinto anazo. Amanzi acocekileyo aquka kuphela icandelo elincinci labemi behlabathi, apho amazwe afana nalawo abumba ilizwekazi le-Afrika achaphazeleka nalapho amanzi anetyiwa egagamela kunye nezixhobo ezinqabileyo zokuwacoca.
Kungumcimbi wokufunda ukubulela ngeli thuba lihle lokusebenzisa amanzi amnandi yonke imihla, ucinga ukuba abantu abanakho ukufikelela kwesi sidingo singundoqo.
Iphulo nokwakha izicwangciso zemfundo ezinxulumene nokugcinwa kweendawo zendalo kunye nokuthintela ukungcoliseka kwendalo; linyathelo elikhulu lokophula ulwazi olungelulo olukhoyo ngalo mbandela.
Emva koko Ukuqinisekisa ukuba oorhulumente badlala indima yokugcina iinkqubo zokucoca amanzi ukusebenzisa kwethu lelinye lamalungelo ekufuneka wonke ummi awasebenzise; ngakumbi kumazwe angenawo amanzi okusela azinzileyo kuba amanzi anetyuwa elawula.
Ukuyijonga nokuyihlonipha njengesixhobo soothixo, kuya kwenza ukuba izizukulwana ezitsha zixabise ixabiso lokwenyani lokusebenzisa amanzi amsulwa kunye nokuhlala kwindawo ecocekileyo.
