Yintoni amanzi anetyuwa amanzi? Le etyuwa of the World Ocean

iplanethi yethu ligutyungelwe ngamanzi nge-70%, apho ngaphezulu kwe-96% aba ulwandle. Oku kuthetha ukuba uninzi amanzi eMhlabeni enetyuwa. Yintoni amanzi anetyuwa amanzi? Njengoko ichaziwe noko kuxhomekeke? Ndingasebenzisa lo manzi efama? Makhe zama ukuphendula le mibuzo.

Yintoni amanzi anetyuwa amanzi?

amanzi yokwanda uba inxalenye enkulu yehlabathi. Kudla ibizwa ngokuba ndifuze equlethwe elwandle, Ezilwandle nasemanzini amanye amachibi. Wonke amanye acocekileyo, ubungakanani yayo uMhlaba ngaphantsi kwe-4%. Phambi kokuba uqonde ukuba amanzi anetyuwa amanzi, kufuneka uqonde ukuba ityuwa.

Iityuwa kukhona izinto ezinzima ezithi iqanjwa ukuse- (ion ngokuqinisekileyo wamwisela) kunye anions zesinyithi (ion kakubi ebizwayo) iziseko acid. Lomonosov zachazwa ngokuba "umzimba ethe ukuba iyanyibilika emanzini." Le olwandle ithe yachithwa izinto ezininzi. Iqulethe sulfates, nitrate, phosphate, iyatshi- isodiyam, nemagnesium, rubidium, potassium, njl Nangona kunjalo, ezi izinto zimiselwe njengoko iityuwa.

Ngoko ke yintoni na amanzi anetyuwa amanzi? Oku umxholo kwezinto ichithwe kuyo. Oku kulinganiswa kumawaka units - PPM, oxeliweyo yi uphawu ezikhethekileyo -% of. PPM kugqiba inani grams ikhilogramu zamanzi.

Yintoni egqibayo amanzi anetyuwa amanzi?

Kwiindawo ezahlukeneyo kwehayidrosfere, yaye ngamaxesha ahlukeneyo konyaka yokwanda lohlukile. Oku ukutshintsh izinto ezininzi:

• uwase;
• ukuyilwa omkhenkce;
• imvula;
• linabantu ice;
• nangodaka;
• zima.

Njengoko amanzi aphuma ngokomphushu ukusuka phezu iityuwa ocean zingatsalelwa badlula. Ngenxa yokuba ukunyuka ingqalelo. neziphumo ezifanayo inkqubo amazinyo. Ezihambayo ziqulathe inkoliso amatsha-langa. Ngexesha nokudaleka amanzi anetyuwa yamanzi kolwandle uchatha.

Ukunyibilika komkhenkce luphawulwa isiphumo esahlukileyo, ukunciphisa isiqulatho ityiwa. Ukongezelela kubo, umthombo wamanzi acocekileyo na imvula emifuleni elwandle. kwinqanaba ityuwa kwakhona kuxhomekeke kubunzulu kunye nohlobo kwemali.

Ukufumaneka kakhulu-sangqa kumphandle. Ukusondela ezantsi, ubutyuwa ingaphantsi. nemisinga efudumeleyo echaphazela isiqulatho ityuwa ingculaza, ebandayo, phezu koko, oko lifinyele.

Le etyuwa ezilwandle

Yintoni na ubutyuwa kwamanzi olwandle? Thina sele siyazi ukuba akukho efanayo kwiindawo ezahlukeneyo zehlabathi. ukusebenza yayo ixhomekeke ekwizibanzi, imozulu, imigodi, kufutshane kwizibonelelo emlanjeni, njl

Le etyuwa avareji amanzi ezilwandle yi PPM 35. Lubonakala ngokuba xi esezantsi kwezinto kwiindawo ezibandayo kufuphi Arctic Antarctic. Ngoxa ebusika xa umkhenkce ibunjiwe, umlinganiselo ityuwa inyuswe.

Ngenxa yesi sizathu, ngaphantsi ezinetyuwa ulwandle i Arctic Ocean (32%). Umxholo eliphezulu yagubha Indian Ocean. Iquka indawo uLwandle Olubomvu kunye nePersian Gulf, kwakunye ibhanti olusemazantsi yimvula, apho amanzi anetyuwa ukuya ku-36 PPM.

Atlantic kunye Pacific Iilwandle malunga lilingane yoxinaniso kwezinto. amandla abo awusafuni kwindawo ethandwa kwandisa kwimimandla nefumileyo yaye eziluhlaza. Ezinye olufudumeleyo kunye nemisinga abandayo cancel bodwa. Ngokomzekelo, hayi ezinetyuwa Gulf Stream kunye Labrador ityuwa i-Atlantic Ocean.

amachibi kunye neelwandle

Uninzi amachibi ehlabathini - okutsha, njengoko zidla ikakhulu imvula. Oku akuthethi ukuba akukho ityuwa kuzo kwaphela, kanye isiqulatho mncinane kakhulu. Ukuba isixa eziqinileyo zichithakala ngaphezu mille ngalinye, idike uthathwa ukuba anetyuwa okanye iiminerali. ixabiso rekhodi Sea lweCaspian (13%). Eyona inkulu angenawo lake - Lake zamanzi.

ityuwa xi ixhomekeke phezu kwamanzi ushiya idike. Amanzi ahlambulukileyo eliqukuqela, kwaye ezinetyuwa ngakumbi ivaliwe nezivele ukuze abe ngumphunga. Le yeyona iphambili kanjanalo abe amatye, leyo kwasekwa idike. Ngoko ke, kummandla yamawa Shield ngezwe kakuhle enyibilikayo emanzini, ngoko ke imizimba amanzi apho "acocekileyo".

Sea ezinxulumene elwandle nge ezingxingongweni. ophelelwe sabo ngandlel ezahlukeneyo kwaye zichaphazela amanzi olwandle avareji. Ngoko ke, kwindlela ekwakugquba ngayo izinto kule kwiMeditera, umalunga-39% yaye ziboniswe kwi Atlantic. ULwandle Olubomvu nomfuziselo 41% ye ngamandla kuphakamisa-avareji etyuwa le Indian Ocean. ityuwa Top Dead Sea ukho xi kwezinto ivela 300 ukuya 350%.

Iimpawu kunye nokubaluleka kwamanzi olwandle

Ityuwa amanzi asifanele ishishini. Asinto ayifanelekile ukusela kunye nonkcenkceshelo. Noko ke, abaninzi elide-eziphilayo bebeziqhelanisa abahlala kuyo. Ngaphezu koko, ecingela kakhulu utshintsho kwizinga sisongo sayo. Ngokusekelwe kule, eziphilayo zahlulwe amanzi kunye ndifuze.

Umzekelo, izilwanyana nezityalo eziphila elwandle, akakwazi kuhlala imilambo fresh yamanzi kunye namachibi. ulwandle kakhulu aba iimbaza ezityiwayo, oononkala, jellyfish, dolphins, iminenga, ookrebe kunye nezinye izilwanyana.

Indoda Ukusela usebenzisa amanzi acocekileyo. Ityuwa isetyenziselwa iinjongo amayeza. intwana yamanzi ngetyuwa ulwandle kudliwe achache. ukusebenza therapeutic yenza ukuqubha kunye ukuhlamba emanzini olwandle.
