Answer to Question 1A rock is a naturally occurring aggregate of minerals, while minerals are naturally occurring, inorganic
crystalline solids. Rocks are made up of minerals, not vice versa.
Answer to Question 2A mineral is a naturally occurring, inorganic, crystalline solid with a narrowly defined chemical
composition and characteristic physical properties. Naturally occurring: a manmade substance cannot
be a mineral; inorganic: anything that was once alive cannot be a mineral; crystalline solid: constituent
atoms are arranged in a three-dimensional framework; narrowly defined chemical composition: the
chemistry of a mineral may vary but within a very specific range.
