I don't get this either. :( A certain rock has large crystals of feldspar mica and quartz. explain how and where the rock might have formed.

Deep below Earth surface where magma cools slowly.

The answer is granite

Explanation:

granite contains feldspar,mica and quartz as well as other things.Granite is known as a igneous rock.Granite is formed when thick magma slowly cools and crystallises long before it is able to reach the Earth's surface.so it is formed in magma

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
