Lesson 3 Reading Guide - Vocab ore gemstone Sources and Uses of Minerals

Lesson 3-1 Minerals are valuable resources used to construct many parts of a home.

Lesson 3-1 Rock that contains high enough concentrations of a desired substance that it can be mined for a profit is called an ore.ore Ores of the elements iron (Fe) and aluminum (Al) are among the most abundant of the metallic mineral resources used every day. Mineral Resources

Lesson 3-1 Aluminum is abundant in Earth’s crust but rarely occurs as a native element. Gold occurs in a ration of 1 part gold to 4 billion parts rock in Earth’s crust, but in large enough concentrations to be mined for profit. The technology industry is dependent upon metallic mineral resources like platinum. Mineral Resources (cont.)

Lesson 3-1 Humans use nonmetallic minerals that are not ores, such as the raw materials used for road construction, building stone, and fertilizers. Mineral Resources (cont.)

Lesson 3-1 A gemstone is a rare and attractive mineral that can be worn as jewelry after it is cut and polished.gemstone Mineral Resources (cont.)

Lesson 3-1 The physical properties of gemstones also make them useful in industry. Sometimes human-made gems are less expensive than the same natural gems. Mineral Resources (cont.)

Lesson 3 - VS An ore contains high enough concentrations of a desired substance that it can be mined at a profit. Mineral resources are used in the construction of buildings, cars, and planes. A gemstone is a valuable mineral known for its beauty, rarity, or durability.
