Mineral Resources (2 types)
Metal Nonmetal
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.
SiO2 ~ glass
CO2 ~ carbon dioxide
H2O ~ water
Ores
Deposits of minerals, from which metals and nonmetals can be profitably removed.
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.

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.

Placer Deposits
Ores are deposited in one of two ways.
1. Settle in curve of a stream
2. Settle in “pockets” in a stream.
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.
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.
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).
