About This Chapter
Environmental Impacts of Earth's Natural Resources - Chapter Summary
Use this chapter's lessons to review information on the Earth's renewable and non-renewable natural resources. Our instructors will present facts on economic geology, energy conservation and energy efficiency. Other lessons look at mineral concentration and the location of mineral deposits.
You'll review information on the environmental impact of coal mining and the extraction of oil and natural gas as well as hydraulic fracturing, more commonly called fracking. After watching all these lessons, you'll be ready to:
- Name differences in renewable and non-renewable resources
- Discuss economic geology
- Analyze the benefits and disadvantages of biomass for renewable energy
- Look at plate tectonics and the relationship to mineral deposits
- List the pros and cons of using geothermal energy
- Differentiate between energy conservation and energy efficiency
- Report on technologies that can make coal mining cleaner
- Explain how oil and natural gas reserves are extracted
- Describe how humans have impacted the environment
These lessons are developed and taught by expert instructors, and you can contact them if you have any questions. They've created multiple-choice quizzes on each lesson. These quizzes allow you to test your learning and see where you may need further review.
1. What Are Natural Resources? - Definition & Types
Natural resources are materials provided by the Earth that humans can use to make more complex (human-made) products. In this lesson, you will learn some examples of natural resources and how to classify them.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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).
10. 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.
11. 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.
12. Human Impacts on the Environment
The human population continues to grow, but the size of Earth and the resources available for our use are limited. Humans greatly impact the world around them, and our actions can and often do have dramatic and long-lasting consequences.
