Ukuqhuma kweVolcano ye-DIY
Ububanzi bevolcano 12.5 * ukuphakama 7cm, ubungakanani bebhokisi yombala wesiNgesi 16 * 21 * 7cm
Ukuqhuma kwe-volcanic, igama elisetyenziswe kwi-geology, yinto ekhethekileyo ye-geological, ukubonakaliswa kwentshukumo ye-crustal, kunye nokubonakaliswa okunamandla kwamandla ashushu ngaphakathi emhlabeni. Kukukhutshwa kwemagma kunye nokunye ukuqhuma okusuka kumngxuma ukuya kumphezulu ngexesha elifutshane. Ngenxa yokuba i-magma iqulethe isixa esikhulu semicimbi eguqukayo kunye noxinzelelo oluxineneyo lwengxondorha engaphezulu, le micimbi iguqukayo ayinakuphuphuma xa inyibilike kwimagma. Xa i-magma inyukela kufutshane nomphezulu womhlaba, uxinzelelo luyancipha kwaye umba oguqukayo ukhutshwa kabukhali, ngaloo ndlela uyila ugqabhuko-dubulo lwentaba-mlilo. Ukuqhuma kwentaba-mlilo kwenza intaba-mlilo.
