Amadwala e-igneous akhiwa ngenxa yokupholisa kwe-magma endaweni engaphakathi yomhlaba
Impendulo ithi: kwesokudla.
I-Igneous rock wuhlobo lwedwala elakhiwe ukupholisa nokuqiniswa kwe-molten magma.
Lawa matshe atholakala ngaphansi komhlaba futhi angamanye amatshe amadala kakhulu emhlabeni.
Inqubo yokwakheka kwayo iyinkimbinkimbi, ihilela izinqubo ezihlukahlukene ze-geological kanye namazinga okushisa.
Inqubo yokupholisa iqala ngokuthi i-magma ikhuphukele phezulu, lapho iphola khona ngokushesha futhi iqine ibe amadwala avuthayo.
Njengoba i-magma iphola, yakha izinhlobo ezahlukene zamaminerali, ezinikeza amatshe avuthayo izakhiwo zawo eziyingqayizivele.
Amatshe ama-igneous atholakala ezindaweni eziningi emhlabeni jikelele futhi abalulekile ekuqondeni ukuthi iplanethi yethu yakheka kanjani phakathi nezigidi zeminyaka.
