Kungani amanzi olwandle enosawoti

Izilwandle nezilwandle kube futhi kuyizinto ezicwaningwa umphakathi wesayensi. Futhi kungenxa yokuthi ingxenye enkulu yezinto eziphilayo ezihlukahlukene zeplanethi yonke itholakala kulobu bubi futhi inani elikhulu lezinsiza likhishwa kubo. Nokho, kunombuzo umphakathi wonke ohlale uwubuza. Abantu abaningi abazi Kungani amanzi olwandle enosawoti.

Ngenxa yalesi sizathu, sizonikezela lesi sihloko ukukutshela ukuthi yiziphi izizathu eziyinhloko zokuthi kungani amanzi olwandle enosawoti nokuthi kubaluleke kangakanani lokhu ekuthuthukisweni kokuphila kulezi zindawo.

Usawoti njengento eyinhloko

Usawoti uyinhlanganisela yamaminerali eyakhiwe ngamaminerali ahlukahlukene. Eqinisweni, lokho esivame ukukubiza ngokuthi "usawoti" uhlobo olulodwa lukasawoti, kodwa kunezinhlobo eziningi zikasawoti wamaminerali ezingatholakala emvelweni. Ngale ndlela, lapho sikhuluma ngosawoti, sibhekisela kunhlanganisela, i-sodium chloride, okuyi-molecule eyakhiwe ama-athomu e-sodium ne-chlorine.

Uma sithola lo sawoti emvelweni, siwubiza ngokuthi i-halite, okuyigama le-mineral common salt. Nokho, usawoti omningi esiwuthola ezimpilweni zethu (ikakhulukazi ekudleni) awuveli kusawoti wamatshe, kodwa uphuma kusawoti wasolwandle. Lapho amanzi olwandle esoma, ingxenye yoketshezi kuphela, amanzi, iyahwamuka. Ngakho-ke, ezinye izingxenye eziqinile ezincibilikisiwe emanzini ziyahlukaniswa futhi zibe esimweni esiqinile esibizwa ngokuthi i-saltpeter.

I-Saltpeter ikakhulukazi yakhiwa usawoti wetafula (i-sodium chloride), nakuba iqukethe amaminerali amaningi ngokwemvelo ancibilika emanzini olwandle. Lapho usawoti uhlukaniswa nenye ingxenye ye-saltpeter, kutholakala usawoti ovamile noma wetafula, okungukuthi, usawoti esiwusebenzisa ukuze sinambithe ukudla kwethu.

Kungani amanzi olwandle enosawoti?

Impendulo ilula: izigidi zeminyaka, imifula ibeke usawoti wamaminerali ahlukahlukene kusukela ekugugulekeni kwamatshe olwandle. Ngokuhamba kwesikhathi, ukwakheka kwalezi zinsalela kuye kwaphumela esilinganisweni senkomba kasawoti, noma usawoti, ongamaphesenti angu-3,5 emanzini amaningi olwandle, noma amagremu angu-35 kasawoti ilitha ngalinye lamanzi.

Izakhi ezimbili eziyinhloko ezikhona emanzini olwandle i-chlorine (1,9%) ne-sodium (1%)., okuthi uma kuhlangene kudale i-sodium chloride noma usawoti wetafula. Ngaphezu kwemisinga egeleza olwandle, kunezinye izenzakalo ezibangela ukwanda kukasawoti, njengokuncibilika kweqhwa, ukuhwamuka kwamanzi, ukuqhuma kwentaba-mlilo kanye nezintuba ezishisayo.

Eqinisweni, ungathola izindawo emhlabeni ezinosawoti. Nokho, lezi yizindawo ezikhethekile ngoba usawoti omningi oseplanethini yethu ugxile ku-brine. Lokhu kungenxa yeqiniso elilula lokuthi usawoti uncibilika kalula emanzini.

Ekuqaleni kweplanethi yethu, wonke usawoti wasakazwa ngendlela efanayo endaweni eshisayo yoMhlaba. Kodwa njengoba ingaphezulu liphola futhi amanzi oMhlaba eshintsha esuka kwigesi eya oketshezi, izilwandle zokuqala zakha. Khona-ke, umjikelezo wamanzi nawo uyaqala. Lo mjikelezo wamanzi usho lawo manzi olwandle liyahwamuka libe amafu, amafu akhiphe imvula, imvula yakhe imifula, futhi ekugcineni imifula ibuyisela amanzi olwandle, kanjalo iphelelise umjikelezo.

Njengoba sishilo, usawoti waqale wasakazwa kuwo wonke umhlaba. Lapho umjikelezo wamanzi uqala, amanzi emvula ancibilikisa usawoti ongaphezulu futhi aqale amuncwa imifula, iwudlulisele olwandle. Nokho, lapho amanzi olwandle ehwamuka, usawoti uhlala olwandle, ngakho njengoba umjikelezo wamanzi uqhubeka uziphindaphinda, ukugcwala kukasawoti emanzini olwandle kuyanda, futhi ngesikhathi esifanayo, indawo engaphezulu yehla kancane kancane. Ezigidini zeminyaka kamuva, wonke usawoti uthathwa amanzi, okubangela ukuba ugxile ngokuphelele olwandle lweplanethi yethu.

Usawoti ubeka phezu komhlaba

Eqinisweni, idiphozithi yemvelo kasawoti isengatholakala kwezinye izindawo emhlabeni. Lokhu kungaba ngenxa yezizathu ezimbili ezahlukene. Ngakolunye uhlangothi, kungase kube indawo lapho umjikelezo wamanzi uhlulekile ukuncibilikisa amadiphozithi okuqala e-saltpeter kusukela ezikhathini zangaphambili. Ngale ndlela, bangamatswayi amaminerali abesendaweni efanayo kusukela kwazalwa umhlaba.

Ngakolunye uhlangothi, ungathola ezinye izigodi ezinosawoti ngokulinganayo noma ulwandle oluphakathi nezwe. Lokhu kungenxa yokuthi umjikelezo wamanzi ushintsha usawoti wasekuqaleni wendawo. Nokho, ngenxa yokuma kwayo, le ndawo ayikaxhumani futhi ixhumene nolwandle olukhulu. Ngale ndlela, inani likasawoti elingakwazi "ukuphunyuka" kulezo zindawo, ngokuvamile ngenxa yokuthi litholakala ezindaweni ezikude ezintabeni. Njengoba nje usawoti ugcwele olwandle, nawo ugxile ezindaweni eziphansi noma ezigodini ezingazodwa zezinhlelo ezithile zezintaba, kodwa kulokhu, naphezu kwezigidi zeminyaka, usawoti awukwazi ukushiya lezi zingosi kusukela umjikelezo wamanzi waqala njengoba usudlulile. Ngokwesibonelo, yilokho okwenzeka oLwandle Olufile.

Ezinye ilukuluku mayelana nokuthi kungani amanzi olwandle enosawoti

Uma usawoti ovela olwandle ungase usabalaliswe ebusweni bomhlaba, ubungakha ungqimba olungaphezu kwamamitha angu-152. Imifula ithwala amathani angaba yizigidi ezi-4 kasawoti oncibilikisiwe iye olwandle.

Omunye umbuzo ohlobene nalesi sihloko ukuthi ingabe amanzi olwandle awusizo empilweni yethu. Ungakwenzi lokhu noma ubulawa ukoma. Impela ngenxa yokugcwala kwawo usawoti omningi, uyingozi kakhulu emzimbeni.. Kwenzekani uma uphuza kakhulu? Amangqamuzana omuntu anolwelwesi oluvimbela ukungena mahhala kukasawoti, kodwa awakwazi ukungena kalula, ngakho angangena kalula engqamuzaneni uma weqa ububanzi obuvunyelwe. Lapho usawoti we-extracellular umkhulu kunosawoti ongaphakathi kwe-intracellular, amanzi aphuma engqamuzaneni ukuze alondoloze ibhalansi ngenqubo ebizwa ngokuthi i-osmosis. Lapho uphuza amanzi olwandle, imiphumela ye-osmosis iyinhlekelele.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi kungani amanzi olwandle enosawoti.
