8. Mineral Resources (2 types) MetalNonmetal Anything classified as a metal on the periodic table. 1.Shiny 2.Conductor of heat and electricity 3.Bendable and ductible

9. Mineral Resources (2 types) MetalNonmetal Anything classified as a metal on the periodic table. 1.Shiny 2.Conductor of heat and electricity 3.Bendable and ductible Compounds of metals and nonmetals, or nonmetals on periodic table. SiO 2 ~ glass CO 2 ~ carbon dioxide H 2 O ~ water

10. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed.

11. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed. Differentiation As magma cools, the more dense metals sink to bottom of magma, or Earth.

12. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed. Differentiation As magma cools, the more dense metals sink to bottom of magma, or Earth. Contact Metamorphism Hot water spreads throughout cracks in rock. Water evaporates and leaves mineral.

13. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed. Differentiation As magma cools, the more dense metals sink to bottom of magma, or Earth. Contact Metamorphism Hot water spreads throughout cracks in rock. Water evaporates and leaves mineral. Vein Small bands of minerals. Small.

14. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed. Differentiation As magma cools, the more dense metals sink to bottom of magma, or Earth. Contact Metamorphism Hot water spreads throughout cracks in rock. Water evaporates and leaves mineral. Vein Small bands of minerals. Small. Mother lode Lots of veins in one place.

15. Ores Deposits of minerals, from which metals and nonmetals can be profitably removed. Differentiation As magma cools, the more dense metals sink to bottom of magma, or Earth. Contact Metamorphism Hot water spreads throughout cracks in rock. Water evaporates and leaves mineral. Vein Small bands of minerals. Small. Mother lode Lots of veins in one place. Placer Deposits Ores are deposited in one of two ways. 1.Settle in curve of a stream 2.Settle in “pockets” in a stream.

16. THE ONLY SURE WAY TO CONSERVE MINERALS IS CONSERVATION (WHICH MEANS TO USE LESS). 1.Recycling is not bad 2.Using other types of resources is not bad. 3.Conservation is best.

17. Section 11.1 Review 1.What is an ore? 2.Explain how some ores from through the process of contact metamorphism. 3.What are some uses of the metals gold, silver platinum and copper? 4.Explain what is meant by renewable and nonrenewable resources.

18. Section 11.1 Review 1.What is an ore?Minerals that can be mined profitably. 2.Explain how some ores from through the process of contact metamorphism.Ot water will move through cracks in rocks. The water will evaportate, and leave the minerals behind. 3.What are some uses of the metals gold, silver platinum and copper? Gold can be used for conductors, Silver can be used for jewelry, and photographic film, Copper can be used for wiring and pipes. 4.Explain what is meant by renewable and nonrenewable resources. Renewable means it can be replaced in one human lifetime (like a tree), nonrenewable means it cannot be replaced in a lifetime (oil, coal, gold).
