Define the term rock. How do rocks differ from minerals?
What will be an ideal response?
A rock is a solid aggregate of minerals or of mineral-like matter. Rocks may have a single mineral composition (such as marble—formed only of the mineral calcite) or a multimineral composition (such as granite—formed mainly of quartz, orthoclase, plagioclase, and biotite), or be made of nonminerals (such as coal—formed from heated and compressed plant matter, or pumice, which is formed from volcanic glass). Minerals, by contrast, have a very specific definition.
