Kuyini ungqimba lwe-ozone

Ungqimba lwe-ozone ungqimba thinnest, futhi kanyekanye ukukhanya emkhathini, okuyinto cishe ezingeni ukuphakama amakhilomitha 50 ngenhla Earth. Ngokusho kwezazi, lo ku ezahlukene Schroth Earth ukujiya ehluke ngokuphelele nendawo jikelele. Nokho, ngokuvamile lokuhlushwa izidakamizwa emkhathini okwamanje azinakwa. Ngokwesibonelo, uma ukuqoqa yonke impahla kwelinye ungqimba, uzinameke iplanethi yethu, ukushuba we ungqimba lwe-ozone kuyoba eshumini a milimitha.

Kuyini ungqimba lwe-ozone

Into okuthiwa i-ozone ingenye kwezinhlobo eziningi izinhlayiya zomoya-mpilo, esakhiwa zama-athomu amathathu (O³). Leli nto ezingqimbeni phakathi Stratosphere. Kulapha ngaphansi isenzo ultraviolet emisebeni yelanga ukubola izinhlayiya zomoya-mpilo ku athomu amabili ukuthi kamuva angene ukusabela eziyinkimbinkimbi namanye amangqamuzana, futhi umphumela uba O³ trihydric.

Okufanele ukwazi

Ungqimba lwe-ozone yaziwa ukudlala indima ebalulekile ekuqinisekiseni isimo abahlala emhlabeni. Kuyinto ngiyabonga kuye, ngomqondo ongokomfanekiso, ivinjiwe yingozi zonke izinto eziphilayo, emisebeni ilanga. Sonke siyazi ukuthi imisebe ultraviolet kunganciphisa izivikeli mzimba, kubangele ukusha ngisho kuholele enjalo izifo eziyingozi ezifana nomdlavuza. Ukuze izitshalo nezilwane, lolu hlobo nethonya futhi okungekuhle. Ngakolunye uhlangothi, uma lolu hlobo Ukuvikelwa bebungekho, njengoba ososayensi bathi, ukuphila emhlabeni bekungeke kwenzeke kuphela ezilwandle nakuzo olwandle, lapho izinto eziphilayo emanzini ikholomu kungaba basitshekelwe emiphumeleni elimazayo ilanga. Ngakho, singasho ukuthi ungqimba lwe-ozone uyisihlangu kweqiniso embulungeni, esivikela yona izinkulungwane zeminyaka. Ochwepheshe akakwazi, ngeshwa, ukusho ngokuthe ngqó lapho kumiswa ke. Nokho, ngokuvumelana idatha yakamuva emakamu yalolu ketshezi emkhathini uwile ngokucijile eminyakeni edlule embalwa, okwaholela ekusungulweni okuthiwa izimbobo-ozone. I enkulu umgodi enjalo endaweni phezu Antarctica.

Izizathu ukwakheka imbobo-ozone

Ochwepheshe bakholelwa ukuthi isizathu esiyinhloko lesi simo, okokuqala kunakho konke, umsebenzi ezimbonini lomuntu. Into wukuthi manje kukhona omkhulu isikali kwekhabhoni amakhemikhali ayingozi emkhathini. Ngisho noma manje isintu uzoma yonke imisebenzi yayo, amandla ngokugcwele liyobuyiselwa kuphela ngemva kweminyaka engu-50.

Vienna Convention on Ozone Layer Ukuvikelwa

Umzamo wokuqala ahlangene isimo ukuvikela ungqimba lwe-ozone senziwa ngo-1985, lapho amazwe wasayina okuthiwa Vienna Convention. Lo muzi liye ngokusemthethweni wamemezela nomqondo ukongiwa statosfery indawo, futhi esasayinwa ngo emazweni amaningi. Ukuzibophezela lala mazwe kuhlanganisiwe ekwakhekeni inqubomgomo kazwelonke kanye okwalandela ukuqaliswa izinyathelo okuzokwenziwa okuhloswe ngazo ukunciphisa ukonakaliswa umoya emhlabeni. Kubalulekile wazi ukuthi iSivumelwano Samazwe akazange anikeze isikhathi eqondile uhlelo bamukela noma yimuphi unswinyo emazweni ahluleka ukuhambisana nezinhlinzeko zalo neziqinile.
