Ch. 2: “Renewable and Nonrenewable Resources”

Lesson 2.1: “Earth’s Resources”

Earth’s Resources

• Natural resources provide people with manufacturing materials or energy.

Earth’s Resources

• The definition for natural resources also includes the following:1. All of Earth’s organisms2. air3. water4. soil5. oil6. gas7. ores

Renewable Resources

List and describe 7 different renewable resources:1. food & fiber2. soil3. wind

4. sun 5. water 6. biomass fuels 7. geothermal energy

Nonrenewable Resources

• List and describe 3 different nonrenewable resources:1. ores2. rocks3. fossil fuels

Fossil Fuels

• List and describe 3 different nonrenewable resources known as fossil fuels:1. coal2. petroleum3. natural gas

Fossil Fuels

• Explain the steps in coal formation and describe the composition of each step:1. peat = 50% carbon2. lignite = 70 % carbon3. bituminous coal = 85% carbon4. anthracite = 90% carbon

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%

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.

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.

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%.

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 =

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.
