Answer to Question 1

A rock is a naturally occurring aggregate of one or more minerals.

Answer to Question 2

Resources are concentrations of a useful commodity that may be known or unknown. A reserve is the
part of the resource that is known and can be economically recovered. There are several factors that
may make a resource into a reserve, including geographic location, the value of the commodity, the
distance of the commodity from where it will be used, the market price, and the technology available
for recovering the commodity
