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

2. Earth’s Resources
Natural resources provide people with manufacturing materials or 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 7.6 million short tons of coal and used more than half (4.5 million short tons) of it.
