About This Chapter
Natural Resources & Energy - Chapter Summary
The lessons in this chapter look at the Earth's energy resources. You'll learn about economic geology, mineral deposits and the difference in renewable and non-renewable resources. Other lessons examine concerns with geothermal energy, coal mining and hydraulic fracturing. After watching these lessons, you should be familiar with:
- Differences in renewable and non-renewable resources
- Benefits and drawbacks of biomass for renewable energy
- Plate tectonics
- Pros and cons of geothermal energy
- Energy efficiency and conservation
- Environmental impact of coal mining
- Extraction of oil and natural gas reserves
- Concerns about hydraulic fracturing (fracking)
You can watch these lessons as your schedule permits on a computer or mobile device. The quizzes that accompany them allow you to test your knowledge, and video tags make it easy to return to the lesson to review key topics. Written transcripts are available, too. Some link to text lessons that provide additional information.
1. What is Economic Geology?
Explore the field of geology that provides us with the raw earth materials we need. In this lesson, we'll learn the scope of economic geology and introduce some topics that will be covered in greater detail in the rest of the chapter.
2. How Minerals Become Concentrated
In order to locate valuable mineral resources, geologists have to understand how these resources are concentrated in the earth. This lesson examines the six methods through which valuable minerals are concentrated by natural processes.
3. Renewable & Non-Renewable Resources: Definition & Differences
We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
4. Biomass for Renewable Energy: Pros and Cons
Biomass is organic material that can be used to generate heat, electricity, and even fuel. In this lesson, you will learn about the advantages of this abundant and renewable energy source as well as the disadvantages.
5. Plate Tectonics and the Location of Mineral Deposits
In this lesson, we learn why a large portion of Earth's valuable mineral deposits are located along current and ancient tectonic plate boundaries. We'll also review the types of plate boundaries and how mineral resources are formed at each type.
6. Geothermal Energy: Advantages and Disadvantages
Geothermal energy is heat energy that is stored within the earth. Learn the methods being used to tap into this thermal energy to heat buildings and generate electricity as well as the advantages and disadvantages of this renewable energy source.
7. Energy Conservation and Energy Efficiency: Examples and Differences
Saving energy is an important topic, but energy conservation and energy efficiency are not the same thing. Learn what the difference is and some examples of both energy conservation and energy efficiency.
8. Coal Mining: Environmental Impacts and Technologies Used To Make Cleaner Coal
Coal is an abundant fuel source, but burning coal is problematic for the environment. In this lesson, you will learn about clean coal technologies, such as coal washing, flue gas desulfurization systems, low-NOx burners, gasification, and Carbon Capture and Storage (CCS).
9. Oil and Natural Gas Reserves: Availability, Extraction and Use
Oil and natural gas reserves are found underground and must be extracted using a drilling method. In this lesson you will learn about the many uses of oil and natural gas, the availability of these valuable resources and how they are extracted.
10. Shale Gas: Hydraulic Fracturing and Environmental Concerns
Shale gas is a type of natural gas that is found trapped within sedimentary rock. It is extracted using a procedure called hydraulic fracturing. In this lesson, you will learn about hydraulic fracturing and the environmental concerns raised by use of this extraction technique.
