Pogwiritsa ntchito mankhwala ndi zinthu m'thupi, mpweya (C) umachitika nthawi zonse. Izi ndizofunikira pa zinthu zonse zamoyo. Maatomu a kaboni amangoyendayenda m'malo osiyanasiyana padziko lapansi. Chifukwa chake, kuzungulira kwa Carboniferous kumawonetsa kusintha kwa moyo Padziko lonse lapansi.
Momwe kayendedwe ka kaboni kamagwirira ntchito
Kaboni wambiri amapezeka mumlengalenga, womwe umapangidwa ngati kaboni dayokisaidi. Malo okhala m'madzi mulinso mpweya woipa. Nthawi yomweyo, momwe kuzungulira kwa madzi ndi mpweya kumachitika m'chilengedwe, kufalikira kwa C kumachitika m'chilengedwe. Ponena za carbon dioxide, imasakanizidwa ndi zomera zochokera mumlengalenga. Kenako photosynthesis imachitika, pambuyo pake zimapangidwa zinthu zosiyanasiyana, kuphatikizapo kaboni. Mtengo wonse wa kaboni wagawidwa m'magawo:
- zina zimatsalira pakupanga mamolekyulu azomera, kukhalapo mpaka mtengo, duwa kapena udzu utafa;
- pamodzi ndi zomera, kaboni imalowa mthupi la nyama ikamadya zomera, ndipo popuma imatulutsa CO2;
- nyama zodya nyama zikamadya chakudya chodyera, ndiye kuti C imalowa m'thupi la adani, kenako imamasulidwa kudzera m'mapweya;
- Mpweya wina wotsalira mu zomerazo umalowa m'nthaka zikafa, ndipo chifukwa chake, mpweya umaphatikizana ndi maatomu azinthu zina, ndipo onse amatenga nawo gawo pakupanga mchere wamafuta ngati malasha.
Chithunzi chozungulira cha kaboni
Mpweya woipa ukalowa m'malo am'madzi, umasanduka nthunzi ndipo umalowa mlengalenga, kutengapo gawo pakuzungulira kwamadzi m'chilengedwe. Gawo lina la kaboni limasakanikirana ndi zomera ndi nyama zam'madzi, ndipo zikafa, kaboniyo amasonkhana pansi pamadzi pamodzi ndi zotsalira za zomera ndi nyama. Gawo lalikulu la C limasungunuka m'madzi. Ngati kaboni ndi gawo lamiyala, mafuta kapena sedimentary, ndiye kuti gawoli latayika mlengalenga.
Tiyenera kudziwa kuti kaboni imalowa mlengalenga chifukwa cha kuphulika kwa mapiri, pomwe zolengedwa zamoyo zimapuma mpweya woipa komanso zotulutsa zinthu zosiyanasiyana mafuta akawotchedwa. Pankhaniyi, asayansi tsopano atsimikiza kuti kuchuluka kochulukirapo kwa CO2 kumachulukirachulukira mlengalenga, zomwe zimabweretsa kutentha. Pakadali pano, kuchuluka kwazida izi kumayipitsa mpweya, kumakhudza chilengedwe cha dziko lonse lapansi.
Kanema Wopanga Mpweya Wa Carbon
Chifukwa chake, kaboni ndiye chinthu chofunikira kwambiri m'chilengedwe ndipo imagwira nawo ntchito zambiri. Dziko lake limadalira kuchuluka kwake pachikopa china cha Dziko lapansi. Kuchuluka kwa kaboni kumatha kubweretsa kuwonongeka kwa chilengedwe.
