A crystal of quartz may be part of granite, sandstone, and the metamorphic rock quartzite. Identify how that same crystal could be
found in all three rocks at different times.

HELP ME WITH THIS QUESTION

The list of minerals that commonly form rocks is short. With a little practice you will recognize most of them when you see them. Descriptions of some of the minerals, as they look in rocks, follow Quartz is the last mineral to crystallize, so in igneous rocks it never has any definite shape. In rocks, it does not show flat faces. It is usually gray in igneous rocks; gray, white, yellow, or red in sedimentary rocks; and gray or white in metamorphic rocks. It has a glassy, or sometimes waxy, look to it. Hope this helps :)

Forgot the question hahaha
