What are the four major rock-forming minerals?
they are quartz, mica, feldspar, and calcite.
Calcite bubbles when it comes in contact with hydrochloric acid because the calcite releases?
Either a. Quartz. b. Calcite. c. Feldspar. d. Mica
What minerals occur in granite?
Granite is composed of feldspar, quartz, biotite and muscovite mica. It has a high amount of silica. Granite is an igneous rock.
Why is quartz abundant in soils?
Quartz is abundant in soils for three reasons. First, it is an abundant mineral to begin with. Second, it is hard and tough; it doesn't break up and crumble into smaller and smaller pieces very easily. Third, it's more resistant to water and weathering than most other minerals you'll find at the surface of the Earth. Consider granite. It contains quartz, feldspar, and mica. Water eventually degrades the feldspar and mica to clay minerals, but it leaves the quartz behind.
