Zonke izici zingabangela isimo sezulu ngaphandle
Impendulo ithi: amandla adonsela phansi.
Zonke izici zingabangela isimo sezulu ngaphandle kwalezo ezingashiwongo uthisha we-geography noma uthisha we-sociology futhi ezingashiwongo encwadini yomfundisi.
Lokhu kuhlanganisa ukumuncwa kwamanzi, inqubo yokuguqula ubuso bomhlaba ngokuhlukana kwamadwala, nezinye izinqubo okungenzeka ukuthi azinakwa.
Isici esiyinhloko esimweni sezulu esingokomzimba ukuqhwaza kwamanzi emifantwini kanye nokwanda lapho lokhu kwenzeka, okubangela ukuba idwala liqhekeke ukuze livumele ukwanda okwengeziwe.
Ezinye izici zihlanganisa ukushintsha komoya nezinga lokushisa, ukusabela kwamakhemikhali afana ne-oxidation, izinqubo zebhayoloji ezifana nokukhula kwezitshalo, nokuguguleka kwezinhlayiya ezinjengesihlabathi.
Zonke lezi zici zingaholela esimweni sezulu esingokomzimba ngokuhamba kwesikhathi, nakuba ezinye zingase ziphumelele kakhulu kunezinye kuye ngokuthi isimo sezulu kanye nendawo ezenzeka kuyo.
