Mzunguko wa jiokemia ya kaboni-silicate, pia unajulikana kama mzunguko wa kaboni isokaboni, unaelezea mabadiliko ya muda mrefu ya miamba ya silicate hadi miamba ya kaboni kwa hali ya hewa na mchanga, na mabadiliko ya miamba ya carbonate kurudi kwenye miamba ya silicate kwa metamorphism na volkano . [1] [2] [3] Dioksidi kaboni huondolewa kutoka angahewa wakati wa mazishi ya madini yaliyokauka na kurudishwa angani kupitia volkano . Katika mizani ya muda ya miaka milioni, mzunguko wa kaboni-silicate ni jambo muhimu katika kudhibiti hali ya hewa ya Dunia kwa sababu inadhibiti viwango vya kaboni dioksidi na kwa hiyo joto la kimataifa. [3]
Kiwango cha hali ya hewa ni nyeti kwa mambo ambayo yanabadilisha ni kiasi gani cha ardhi kinafunuliwa. Sababu hizi ni pamoja na usawa wa bahari, topografia, litholojia, na mabadiliko ya mimea . [5] Zaidi ya hayo, mabadiliko haya ya kijiografia na kemikali yamefanya kazi sanjari na nguvu ya jua, iwe kutokana na mabadiliko ya obiti au mabadiliko ya nyota, ili kubainisha halijoto ya uso wa dunia . Zaidi ya hayo, mzunguko wa carbonate-silicate umezingatiwa kuwa suluhisho linalowezekana kwa kitendawili cha vijana dhaifu cha Sun. [6]
