Kwiplanethi yethu, izinqubo ezahlukahlukene zamakhemikhali, zomzimba, zebhayoloji zenzeka ngokubamba iqhaza kwezinto nezinto. Zonke izenzo zenzeka ngokuya ngemithetho yemvelo. Ngakho-ke, izinto ezisemvelweni yemvelo ziyajikeleza, zibamba iqhaza kuzo zonke izinqubo ebusweni bomhlaba, emathunjini eplanethi nangaphezulu kwawo. Inzuzo yezinto ezahlukahlukene inemvelo yokujikeleza, equkethe ukuguqulwa kwento isuka kokuphilayo iye kokungajwayelekile. Yonke imijikelezo ihlukaniswe ngemijikelezo yegesi kanye nemijikelezo yensimbi.
Umjikelezo wamanzi
Ngokwehlukile, kufanelekile ukugqamisa umjikelezo wamanzi emvelweni. Kubhekwa njengengxenye ebaluleke kakhulu kukho konke ukuphila emhlabeni wethu. Umjikelezo wayo umelwe ngale ndlela elandelayo: amanzi asesimweni soketshezi, agcwalisa amadamu, ashise futhi ahwamuke angene emkhathini, ngemuva kwalokho aqoqane bese ewela womabili emhlabeni (20%) naseWorld Ocean (80%) ngendlela yemvula (iqhwa, imvula noma isichotho). Lapho amanzi engena ezindaweni ezinamanzi ezinjengeziziba, amachibi, amaxhaphozi, imifula, emva kwalokho aphinde aphumele emoyeni. Uma isiphansi, ingena emhlabathini, igcwalise amanzi angaphansi komhlaba nezitshalo ezigcwalisa. Bese kuba ngumphunga ovela emaqabungeni bese ungena emoyeni futhi.
Umjikelezo wegesi
Uma sikhuluma ngomjikelezo wegesi, kufanelekile ukuhlala ezintweni ezilandelayo:
- Ikhabhoni. Imvamisa, ikhabhoni imelelwa yisikhutha, esisuka ekumuncweni izitshalo kuya ekuguquleni ikhabhoni ibe ngamadwala avuthayo nasentabeni. Ingxenye yekhabhoni idedelwa iye emkhathini ngesikhathi somlilo wephethiloli oqukethe ikhabhoni
- Oxygen. Kuqukethe umkhathi, okhiqizwa izitshalo njengomphumela we-photosynthesis. U-oksijeni ovela emoyeni ungena emzimbeni wezinto eziphilayo ngomgudu wokuphefumula, uyadedelwa uphinde ungene emkhathini
- I-nitrogen. I-nitrogen ikhishwa ngesikhathi sokuwohloka kwezinto, ifakwa enhlabathini, ingena ezitshalweni, bese ikhishwa kuzo ngesimo se-ammonia noma i-ammonium ions
Ama-gyres we-sedimentary
I-Phosphorus itholakala emadwaleni nakumaminerali ahlukahlukene, ama-phosphations angaphili. Kunezakhi ezithile eziqukethe i-phosphorus kuphela ezincibilika emanzini, futhi zimuncwa izimbali kanye noketshezi. Ngokuhambisana neketanga lokudla, i-phosphorus yondla zonke izinto eziphilayo, eziyikhiphela emvelweni kanye nemikhiqizo kadoti.
Isibabule sitholakala ezintweni eziphilayo ngesimo sezinto eziphilayo ezisebenzayo, kwenzeka ezifundeni ezahlukahlukene. Kuyingxenye yezinto ezahlukahlukene, ingxenye yamatshe athile. Ukusakazwa kwezinto ezahlukahlukene emvelweni kuqinisekisa inkambo yezinqubo eziningi futhi kubhekwa njengento ebaluleke kakhulu emhlabeni.
