Basics of Environmental Science - Chapter Summary
This chapter contains a collection of fun lessons covering the basics of environmental science. Work through topics such as greenhouse gases and recycling at your leisure. Once completed, you should be able to:
- Outline greenhouse gases and the enhanced greenhouse effect
- Identify the 3 Rs of reducing solid waste
- Discuss the differences between renewable and non-renewable resources
- Define renewable energy
- Explain physical, chemical and biological pollution
If these concepts have been challenging for you in the past, this chapter makes them approachable and easy to understand. You can work at your own pace as you review as many or as few of the lessons as you need. Take the self-assessment quiz included with each lesson to ensure that you're ready for the test.
1. Pollution: Physical, Chemical & Biological
Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.
2. Greenhouse Gases and the Enhanced Greenhouse Effect
In this video lesson, you will learn about the five main greenhouse gases and how their unnaturally high concentrations are leading to the enhanced greenhouse effect and global climate change on Earth.
3. The 3 Rs of Reducing Solid Waste: Reuse, Reduce & Recycle
Reduce, reuse, recycle! In this lesson, we will explore the three Rs of reducing solid waste. We will also investigate examples of each of the three Rs, and how people can do their part to help reduce solid waste.
4. 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.
5. What Is a Renewable Energy Source? - Definition & Example
Right now, you are using electricity to power your computer. Most of our power comes from nonrenewable sources that can run out. In this lesson, learn about the many types of renewable energy sources that will never run out and could be used instead.
