Ukwakhiwa komoya

Leyo ngxenye yomkhathi ohlangene noMhlaba futhi ephefumulelwe umuntu, ibizwa ngokuthi troposphere. I-troposphere inokuphakama kwamaphesenti ayisishiyagalolunye kuya kweshumi nesishiyagalolunye futhi iyinhlanganisela yemishini yezinhlobo ezihlukahlukene zegesi.

Ukubunjwa kwomoya akuhlali njalo. Kuye ngokuthi indawo yendawo, indawo, izimo zesimo sezulu, isibalo sabantu, umoya ungaba nokwakhiwa okuhlukile nokwakhiwa okuhlukile. I-air ingasulwa noma ikhishwe, intsha noma inzima - konke lokhu kusho ukuthi kunezingcola ezithile.

Kodwa-ke, kuyisiko ukucabangela ukubunjwa kwomoya okulandelayo njengendlela ejwayelekile:

- i-nitrogen - amaphesenti angu-78,9;

- oksijini - amaphesenti angu-20.95;

- I-Carbon dioxide - amaphesenti angu-0.3.

Ngaphezu kwalokho, amanye ama-gesi (i-helium, i-argon, i-neon, i-xenon, i-krypton, i-hydrogen, i-radon, i-ozone), kanye ne- nitrous oxide nomoya wamanzi zikhona emkhathini . Isamba sabo singaphansi kwamaphesenti ayisithupha.

Kumele futhi kubhekisele ekubeni khona emoyeni kwamanye ama-admixtures angunaphakade emvelaphi yemvelo, ikakhulukazi, eminye imikhiqizo ye-gaseous eyenziwa ngenxa yezinqubo ezimbili zezinto eziphilayo nezomakhemikhali. Ama-Ammonia afanele akhulume ngokukhethekile phakathi kwabo (ukubunjwa kwendiza kude nezindawo ezinabantu abaningi kubandakanya cishe amamitha ayizinkulungwane ezintathu kuya kwezinhlanu ezinhlanu ngamamitha ayi-cubic meter), i-methane (izinga elilinganiselwe lalingamaphesenti amabili ayizinkulungwane eziyishumi ze-milligram ngamamitha ayi-cubic ngamunye), i-nitrogen oxides (emkhathini ukuhlushwa kwabo kufinyelela Cishe izinkulungwane eziyishumi nanhlanu eziyishumi ze-milligram ngamamitha ayi cubic), i-hydrogen sulphide nezinye imikhiqizo ye-gaseous.

Ngaphezu kokungcola kanye nokungcola kwegesi, ukwakhiwa kwamakhemikhali kaningi kubandakanya uthuli lwendalo, eliwela emkhatsini womhlaba ngamanani ayizinkulungwane ezingamakhulu ayisikhombisa ekhreyitha ngalinye ngehora lesikhathi sonyaka, kanye nezinhlayiya zothuli ezivela ekukhuphukeni kwezintaba-mlilo.

Kodwa-ke, ukwakheka komoya kuyashintsha kakhulu kakhulu (futhi hhayi okungcono kakhulu) kanye nomhlabathi okuthiwa (isitshalo, inhlabathi) uthuli nomusi ovela ehlathini ukushisa ukungcolisa i-troposphere. Ikakhulukazi inqwaba yothuli olunjalo emiphakathini ye-continental air, evela emahlane ase-Asia Ephakathi nase-Afrika. Yingakho singasho ngokuqiniseka ukuthi indawo ehlanzekile yomoya ayitholakali, futhi ingumqondo okhona nje kuphela.

Ukwakhiwa kwemoya kunendawo yokuguqula njalo, futhi izinguquko zayo zemvelo ngokuvamile zidlala indima encane, ikakhulukazi uma kuqhathaniswa nemiphumela engenzeka yokuphazanyiswa kwayo. Ukuphulwa okunjalo kuhlotshaniswa kakhulu nemisebenzi eyenza isintu, ukusetshenziswa kwamasevisi ezinsizakalo zabathengi, kanye nezimoto. Lokhu kuphulwa kungabangela, phakathi kwezinye izinto, ukuguqula umoya, okungukuthi, ukuchaza umehluko ekubunjweni kwayo kanye nasezindlini ezivela ema-indices afanayo emkhathini.

Lezi nezinye izinhlobo eziningi zomsebenzi womuntu ziholele ekutheni ukwakhiwa komoya okuqala kuqale ukuhamba kancane futhi kungabalulekile, kodwa kungakhathaliseki ushintsho ngokuphelele. Isibonelo, ososayensi babalwe ukuthi eminyakeni engamashumi amahlanu edlule, isintu sisetshenzisile mayelana ne-oksijeni eningi njengeminyaka eyizigidi ezandulele, futhi ngamaphesenti, imigomo emibili yeshumi yamaphesenti esitokisi sayo esiphezulu emkhathini. Ngesikhathi esifanayo, ukukhululwa kwe- carbon dioxide emvilophini yemoya yenyuka ngokufanayo . Lokhu kukhululwa, ngokusho kwedatha yakamuva, kufinyelele amathani angamakhulu amane amabhiliyoni eminyakeni engamakhulu ayisishiyagalombili edlule.

Ngakho-ke, izinguquko zomoya zishintsha kakhulu, futhi kunzima ukuqagela ukuthi kuzoba kanjani emashumini ambalwa eminyaka.
