Ch 12: OAE Earth & Space Science: Natural Resources

About This Chapter

This chapter gives you a closer look at Earth's natural resources. Watch these convenient video lessons in advance of taking the OAE Earth and Space Science examination to assist in answering questions about minerals, fossil fuels, coal mining, and more.

OAE Earth and Space Science: Natural Resources - Chapter Summary

Watching the videos in this chapter can teach you more about the products and services that can be created from the Earth's raw materials. Through the process of preparing for the OAE Earth and Space Science examination, you'll review some of the methods used to extract minerals. You can also examine the ways in which fossil fuels can be utilized as low-cost energy resources. This chapter's online videos can help you to:

  • Explore economic geology
  • Differentiate between mineral deposits and ore
  • Discuss the concentration of mineral resources
  • Understand the process of finding, extracting and evaluating minerals
  • Describe where Earth's mineral deposits, oil and gas reserves can be found
  • List the advantages and disadvantages of fossil fuels
  • Explore the technologies that create cleaner coal
  • Understand the uses for rangelands
  • Discuss the implications of desertification and deforestation

Expand your knowledge of these topics with the help of the well-qualified lesson instructors. Use the videos as a way to review Earth's natural resources whenever time permits. Video tags make it easy to navigate the lessons. You can also check the written transcripts, submit your questions and take the short self-assessment quizzes that follow each of the lessons.

OAE Earth and Space Science: Natural Resources - Chapter Objectives

Domain II of the OAE Earth and Space Science examination covers geology. Adding up to 25% of the total assessment score, this domain is where you'll translate your grasp of this chapter's material into knowledge-driven test answers. The entire assessment consists of 150 multiple-choice questions. You'll be allowed up to 180 minutes to complete the computer-based examination, but this doesn't include a 15-minute tutorial.

What is Economic Geology?

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.

What Distinguishes Ore from Other Mineral Deposits?

2. What Distinguishes Ore from Other Mineral Deposits?

Ore deposits provide the raw materials that allow our society to function. In this lesson, we'll look at the driving forces that cause ore deposits to be unique from non-valuable mineral deposits.

How Minerals Become Concentrated

3. 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.

Plate Tectonics and the Location of Mineral Deposits

4. 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.

Finding and Assessing Mineral Resources

5. Finding and Assessing Mineral Resources

Because mineral resources are so rare, they are not easy to locate. In this lesson, we'll learn the process that geologists use to find and assess valuable mineral deposits.

Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use

6. Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use

In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.

What Are Fossil Fuels? - Definition, Advantages & Disadvantages

7. What Are Fossil Fuels? - Definition, Advantages & Disadvantages

Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable. Learn more about these fuels, including the pros and cons of using them.

Oil and Natural Gas Reserves: Availability, Extraction and Use

8. 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.

Coal Mining: Environmental Impacts and Technologies Used To Make Cleaner Coal

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).

Rangelands: Uses and Degradation

10. Rangelands: Uses and Degradation

Rangeland covers much of the land area of the world. The lack of rainfall in these areas makes it useful land for grazing livestock and provides environmental benefits. Learn about the uses of rangeland and the potential for rangeland degradation.

Deforestation, Desertification & Declining Biological Diversity

11. Deforestation, Desertification & Declining Biological Diversity

When trees are lost due to deforestation, the result can be a drier climate and desertification or the transformation of the once fertile land to desert. Learn how deforestation and desertification can lead to a decline in biological diversity.
