Ezi molekyuli zamanzi emhlabeni namhlanje bezikho kangangamakhulu ezigidi zeminyaka.Sisenokuba sisela umchamo weedinosaur.Amanzi asemhlabeni akayi kubonakala okanye aphele ngaphandle kwesizathu.
Enye incwadi ethi, The Future of Water: A Starting Look Ahead, ebhalwe nguSteve Maxwell noScott Yates, ibonisa ngokucacileyo ukuba iidinosaur zazisela amanzi afanayo nathi.Amandla efosili aya kunyamalala emva kokutshiswa, kodwa amanzi anokuphinda asetyenziswe ngokuqhubekayo.
Uninzi lwamanzi kwiplanethi yethu ngamanzi anetyuwa, agcinwe elwandle.Malunga nesiqingatha samanzi amatsha aseleyo akhoyo ngendlela yomkhenkce, esinye isiqingatha samanzi aphantsi komhlaba, kwaye inxalenye encinane kakhulu igcinwe kumachibi, imilambo, umhlaba kunye nomoya.Ngaphezu koko, le nxalenye incinane kuphela enokusetyenziswa zizidalwa eziphila emhlabeni.
Amanzi kumadama ahlukeneyo asemhlabeni anokuhamba ngokuqhubekayo.Ngokomzekelo, amanzi omlambo angena echibini, kwaye amanzi asechibini ayakwazi ukungena emhlabeni.Ngamafutshane, amanzi akula madama anokujikeleza ngamaxesha athile.Ngamanye amazwi, amanzi eziwaselwa zizilwanyana zasemhlabeni eziswini zazo aya kuthi ekugqibeleni akhutshelwe kwindalo kwakhona.Ke usela amanzi kwaye iidinosaur nazo zisele.Kukwayinto elungileyo ukucinga ngayo.Ngaphambi kokuvela kwabantu, amanzi emhlabeni aye ajikeleza emzimbeni weedinosaurs izihlandlo ezininzi.
Amanzi esiwaselayo
Ungakanani umchamo wedayinaso okhoyo?
Kuyinyani ukuba abantu badla amanzi amaninzi yonke imihla, kodwa xa kuthelekiswa nowayesakuba yinkosi yomhlaba - iidinosaur, impembelelo yethu emanzini emhlabeni esithubeni kunye nexesha ayinakwenzeka ukuba ifikelele kwinqanaba leedinosaurs eziye zalifumana.Ixesha le-Mesozoic, elaziwa ngokuba yiminyaka yeedayinaso, lathatha iminyaka eyi-186 yezigidi, kwaye italente yamandulo yenkawu yavela kwiminyaka eyizigidi ezisixhenxe edlulileyo.Kwithiyori, ngaphambi kokuvela kwabantu, amanzi emhlabeni aye ajikeleza emzimbeni weedinosaurs kangangezihlandlo ezininzi.
Ingxoxo malunga nokuphinda kusetyenziswe amanzi okusela kunye namanzi isoloko ibandakanya umjikelo wamanzi.Iintatheli kunye noosonzululwazi bayathanda ukuzoba imizobo elula kakhulu okanye engachanekanga ukuchaza inkqubo yomjikelo wamanzi.Ingcamango engundoqo yeyokuba amanzi asemhlabeni namhlanje ayafana nalawo eedinosaurs.
Inani elikhulu leenkqubo zebhayoloji, zomzimba kunye neekhemikhali ziya kuqhubeka kudala amanzi amatsha.Ngoko ke, amanzi anokubonwa njengohlaziyo oluqhubekayo.
Umzekelo, iglasi yamanzi kwidesika yakho ihlala i-ionized kwaye ibolile ibe yi-hydrogen ion kunye ne-hydroxide ion.Emva kokuba amanzi abe yi-ionic, ayisekho i-molecule yamanzi.
Nangona kunjalo, ezi ion ekugqibeleni ziya kuvelisa iimolekyuli ezintsha zamanzi.Ukuba i-molecule yamanzi ihlaziywa ngokukhawuleza emva kokubola, sinokuthi kwakhona kusekho amanzi afanayo.
Ke ukuba siyawusela umchamo wedayinaso okanye hayi kuxhomekeke ekuqondeni kwakho.Kunokuthiwa bekunxilile okanye akunxilanga.
