Concept #8 Quiz
Choose the best possible answer to the following questions about Key Concept 8 "Mineral resources."

This activity contains 4 questions.

	What is the difference between a “resource” and a “reserve” with respect to mining?   reserves are resources of which we do not know or predict the location reserves are resources of which we know the location, or predict the location reserves are resources of which we know the location and cannot mine today only reserves are resources of which we know the location and can mine today only

	What is the difference between what is called an “ore” and what is classified as “industrial rocks and minerals”? Choose the two that apply.   Ores are typically easily mined, whereas industrial materials are usually much more difficult to collect and process. Metallic ores are usually formed by igneous and metamorphic processes, whereas industrial materials are not. Ores are used for building and other construction purposes, whereas industrial materials are useful metallic minerals that are mined. Ores are widespread minerals and rocks, whereas industrial materials are usually much rarer, causing their costs to be relatively higher. Ores are useful metallic minerals that are mined, whereas industrial materials are used for building and other construction purposes.

	When is an element or mineral considered valuable? Choose two that apply.   An element must be located in a "region" at about its average crustal abundance. A mineral must be throughout a rock, and that rock must be in a "region." An element must be concentrated in a "mineral deposit" above its average crustal abundance. An element must be concentrated in a mineral, and that mineral must be concentratied in a "deposit."

	What controls whether or not a deposit is "profitable" for mining? Choose all that apply.   Work force fluctuation. Climate changes. Economic changes. Technological advances.
