About This Chapter
MEGA Earth Science: Energy Resources - Chapter Summary
This chapter's video lessons go into various laws and components of energy resources, detailing in a simple-to-follow fashion all of the following topics:
- The definition of energy
- The first and second law of thermodynamics
- How resources and reserves differ
- Renewable and non-renewable resources and reserves
- The pros and cons of fossil fuels
- Chemical, radiant, and thermal energy
- Wind as a renewable resource
- Solar power and nuclear energy
- Hydroelectric and tidal energy
The lesson transcripts give you another way to review this material on energy resources. After each lesson, you'll have the opportunity to test your knowledge with a practice quiz that you can take and re-take at your discretion.
1. What is Energy? - Definition and Significance in Nature
This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.
2. First Law of Thermodynamics: Law of Conservation of Energy
This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.
3. Second Law of Thermodynamics: Entropy and Systems
In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.
4. Resources and Reserves: Definitions & Examples
You might hear a lot about reserves and resources on Earth, but what exactly is the difference between the two? In this video lesson, you will learn about each, as well as how they represent different things that are quite related to each other.
5. 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.
6. 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.
7. What is Chemical Energy? - Definition & Examples
This lesson describes chemical energy as a type of potential energy stored in chemicals, such as sugar and gasoline. The lesson discusses how energy is transferred from solar energy to chemical energy by plants and how gasoline is a source of chemical energy used to move cars.
8. What is Radiant Energy? - Definition & Examples
This lesson defines and describes radiant energy in its different forms. The different types of electromagnetic waves created by radiant energy are identified and described as well. This includes X-rays, microwaves, and radio waves, to mention a few.
9. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
10. Wind as a Renewable Energy Resource: Advantages & Disadvantages
Wind power is a renewable energy resource, but there are both pros and cons to this type of energy. In this video lesson, you will learn about wind power as well as some of the benefits and drawbacks of using it as a global energy source.
11. What is Solar Power? - Uses, Advantages & Disadvantages
The sun provides us with a constant energy source. In this video lesson, you'll learn how we can harness solar power from the sun. We'll also take a look at the pros and cons of this renewable energy resource.
12. What is Nuclear Energy? - Definition & Examples
You've probably heard of nuclear energy. But what is it? And what is the difference between fusion and fission? This lesson will answer your questions about this exciting form of energy that involves atoms and their nuclei.
13. Hydroelectric Energy: Definition, Uses, Advantages & Disadvantages
In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks of using this type of renewable resource for energy production.
14. Tidal Energy: Advantages and Disadvantages
The tides move a massive amount of water, and the energy from this moving water, known as tidal energy, can be captured and converted into electricity. Learn how tidal energy works and the advantages and disadvantages of this energy source.
