E-troposphere kunochungechunge lwamagesi asivumela ukuthi siphile futhi sikhule njengoba senza namuhla. Lolu chungechunge lwamagesi lwaziwa njengomoya. Umoya uyinto ebalulekile yokuphila emhlabeni wethu. Akubalulekile kuphela kumuntu, kodwa kunoma yikuphi ukuphila kwanoma yisiphi isidalwa esiphilayo. Ukubaluleka komoya akunakuphikiswa, njengokubaluleka kwamanzi. Akuwona wonke umuntu owazi ukwakheka komoya esiwuphefumulayo nokuthi kungani kubaluleke kangaka.
Yilokho esilapha namuhla. Kulesi sihloko sizokhuluma nge- ukwakheka komoya, imisebenzi umoya onayo ekuthuthukiseni impilo nokuthi kwenzekani ngokungcoliswa komoya namuhla.
Ukwakheka komoya esiwuphefumulayo
Lapho siphefumula, asigcini ngokufaka i-oxygen esiyidingayo ukuze siphile futhi sikhipha i-CO2 engadingekile emzimbeni. Umoya esiwuphefumulayo wakhiwe ngochungechunge lwamagesi atholakala emvelweni. Ngokusobala, ngemuva kokwakhiwa kweplanethi, ukwakheka komoya osemkhathini wethu bekungafani. Sekuguqukile izigidigidi zeminyaka.
Ekuqaleni kokwakheka kwayo, umkhathi wakudala wawungenakho okuqukethwe oksijini. Lo mkhathi awukwazi ukuhlala abantu noma cishe noma iyiphi indlela yokuphila yamanje. Kuphela amagciwane anaerobic kanye methanogens, ngoba umoya ngaleso sikhathi wawuphakeme kakhulu methane.
Kodwa-ke, njengoba umoya-mpilo ukhona emoyeni, usuphenduke elinye lamagesi amakhulu futhi abaluleke kakhulu. Kodwa-ke, sizobona ukwakheka komoya ezingxenyeni ezithile:
- I-nitrogen. Lo gesi yiwona owenza cishe konke ukushuba kokwakheka komoya. Kuku-78% womoya womkhathi. Kubalulekile ngoba, yize kuyigesi engena kithina, iyinto ebalulekile yama-amino acid kanye ne-nucleic acid. Lezi zinto ziyisihluthulelo sezidalwa eziphilayo. Umuntu wenziwe nge-3% nitrogen. Yinto esiyiphefumulayo ngokugxila okuphezulu kakhulu kuyo yonke i-troposphere.
- Oxygen. Kuyingxenye cishe yama-20% omoya esiwuphefumulayo. Yize i-nitrogen ibalulekile, umoya-mpilo uyinto ebaluleke kakhulu ezintweni eziphilayo. Kuyadingeka ukuthi ukwazi ukuqhuba ukuphefumula. Singathola futhi le nto emzimbeni wethu, ikakhulukazi ohlelweni lokuphefumula.
- I-Carbon dioxide. Yize kuqhubeka kushiwo ukuthi ukugxilwa kwe-carbon dioxide kuyanda ngenxa yokwanda komphumela wokushisa nokushintsha kwesimo sezulu, ithatha kuphela u-0,03% womoya. Ungavumeli lolu lwazi lukudide. Lokhu kuhlushwa kungokwanele ukukhiqiza lokhu kwanda kokushisa emhlabeni jikelele. Kuyinto esiyikhipha njengomkhiqizo odoti ngesikhathi sokuphefumula.
- Amanzi. Kungenye into ebalulekile empilweni yomuntu futhi cishe kunoma yisiphi isidalwa esiphilayo. Emoyeni itholakala nangephesenti elingu-0,97%. Kulokhu, sikuthola ngesimo somhwamuko wamanzi. Ukuhlungwa kwayo akunakunikezwa kuphephe kakhulu ngoba kuncike kakhulu lapho silinganisa khona. Ukugxila komphunga wamanzi emkhathini kuphakeme olwandle kunalapho sikude kakhulu.
Amagesi Noble njengoba ukwakheka komoya
Amagesi ahloniphekile yiwo amagesi angenalutho angasabeli nganoma yini futhi azinzile ngokuphelele. Akubona bonke abanobukhona obufanayo ekwakhiweni komoya, kepha kukonke, bakha i-1% yakho konke. Sinezi gesi:
- I-Argon. Ngugesi omuhle kakhulu okhona kakhulu.
- Neon. Kungugesi omningi ngokwanele endaweni yonke futhi usebenza ekwakheni umoya.
- Helio. Inobuncane ubukhona emkhathini njengoba ukukhanya kwayo bekubangele ukuba kuhwamuke.
- IMethane. Ingenye yamagesi abamba ukushisa abaluleke kakhulu.
- IKrypton. Kuyinto igesi enhle engenakho okuncane.
Ukungcoliswa komoya
Njengoba sishilo phambilini, ukwakheka komoya bekungafani emlandweni weplanethi yethu. Ngaphezu kwalokho, asikhulumi ngokuthi kuyafana emakhulwini eminyaka adlule emuva kuze kube manje. Okuqukethwe kwegesi yokushisa lenyuke kakhulu ngenxa yomsebenzi wabantu. Lawa magesi aphathwa njengongcolisayo ngoba athinta kabi ukuthuthukiswa kwempilo nezimo zemvelo.
Njengoba umoya uyinto ebalulekile ekusindeni kwazo zonke izidalwa eziphilayo, ukungcola esikudalayo kulimaza impilo yethu futhi kwenza izwe esihlala kulo libe libi kakhulu. Ukungcoliswa komoya kungenzeka ngezindlela ezimbalwa. Kodwa-ke, okuvame kakhulu nokuchichima yilokho okubangelwa yimisebenzi yabantu lapho, ikakhulu, singasho ukuthi ziyimboni nezokuthutha. Ngenxa yentuthuko kwezesayensi nobuchwepheshe, nsuku zonke sithumela amagesi amaningi abamba ukushisa emkhathini ayingozi futhi ayingozi uma siwaphefumula futhi siwachaya.
Imvelo inokulingana kwayo kwemvelo, futhi uma ukugxila kwala magesi kungokwemvelo, ayakwazi ukulinganisa ukugxila kwawo futhi akugcine kuzinzile ngokuhamba kwesikhathi. Kodwa-ke, ngomsebenzi womuntu kanye nokuphuma ngokweqile emkhathini, emashumini eminyaka amuva nje kuye kwabangelwa lokho imvelo ayikwazi ukulungisa ngokwayo amaphutha esiwenzayo thina bantu.
Ngenxa yokungcola komoya okuvela la magesi ayingozi, umoya esiwuphefumulayo uyalinyazwa futhi nempilo yazo zonke izinto eziphilayo iyathinteka. Kubalulekile ukwazi lokho ukungcola kungashintsha ukwakheka komoya ekuqaleni, kuvela amagesi anobuthi amaningi kunalapho siphefumula khona. Konke lokhu kuguqulela ezinkingeni zezinto eziphilayo neziphilayo.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngokwakhiwa komoya nokubaluleka kwawo.
