  1. Ch. 2: “Renewable and Nonrenewable Resources” Lesson 2.1: “Earth’s Resources”

  2. Earth’s Resources • Natural resources provide people with manufacturing materialsor energy.

  3. Earth’s Resources • The definition for natural resources also includes the following: 1. All of Earth’s organisms 2. air 3. water 4. soil 5. oil 6. gas 7. ores

  4. Renewable Resources List and describe 7 different renewable resources: 1. food & fiber 2. soil 3. wind   4. sun   5. water   6. biomass fuels   7. geothermal energy

  5. Nonrenewable Resources • List and describe 3 different nonrenewable resources: 1. ores 2. rocks 3. fossil fuels

  6. Fossil Fuels • List and describe 3 different nonrenewable resources known as fossil fuels: 1. coal 2. petroleum 3. natural gas

  7. Fossil Fuels • Explain the steps in coal formation and describe the composition of each step: 1. peat = 50% carbon 2. lignite = 70 % carbon 3. bituminous coal = 85% carbon 4. anthracite = 90% carbon

  8. Fossil Fuels • List the world’s 3 leading coal producers and the percentage of coal they each provide: 1. former Soviet Union = 50% 2. China = 20% 3. US = 15%

  9. Fossil Fuels • Describe the formation and extraction process of petroleum and natural gas: • Oil & gas are the remains plants, bacteria, algae, & other microscopic marine organisms. During millions of years of burial, chemical & physical reactions take place that change the organic matter into liquid & gaseous compounds.

  10. Global Energy Use and Production • Experts say that the world’s total energy consumption increased by nearly 50% from 1973 to 1993. • Is this upward trend expected to continue? Yes • Global coal use is expected to increase more than 50% over the next two decades.

  11. Global Energy Use and Production • Developing nations, especially Asia, will require the greatest increase in coal consumption. • The amount of oil needed is also expected to rise rapidly, predominantly in areas such as China, India and Thailand. Developing nations consume more than half of all commercial energy. • Experts predict that over the next few decades, developing and primarily agricultural nations will increase their share of energy use to nearly 40%.

  12. Alternative Energy Resources • Describe the following types of energy resources: 1. solar energy = 2. wind = 3. hydropower = 4. geothermal energy = 5. nuclear power = 6. trash = 7. hydrogen =

  13. Fossil Fuel Production and Consumption in PA • PA uses more petroleum and natural gas than is actually produced in the state. • PA produced about 7.6million short tons of coal and used more than half (4.5 million short tons)of it.
