About This Chapter

If you need assistance prepping for the CEOE Physical Science exam, you can always get help from us and complete this chapter's engaging video lessons. They contain important information that you will see on the actual test.

CEOE Physical Science: Human Effects on the Environment - Chapter Summary

While you go through the video lessons compiled in this chapter, you will get to strengthen your knowledge of the relationship between humans and the environment. This chapter prepares you to take on any questions about the following:

  • The nitrogen cycle
  • The carbon cycle
  • Fossil fuels and greenhouse gases
  • Different forms of pollution
  • Over-exploitation
  • Habitat destruction

Not only do these lessons help you review different environmental topics, but they can possibly help you pick up new information that you will need to know for the exam. You can take a quiz after each lesson, and a chapter exam can be completed once you've gone through all of the lessons.

Test your knowledge with a 30-question chapter practice test
The Nitrogen Cycle, Acid Rain and Fossil Fuels

1. The Nitrogen Cycle, Acid Rain and Fossil Fuels

Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.

The Carbon Cycle and Long-Term Carbon Storage

2. The Carbon Cycle and Long-Term Carbon Storage

All living organisms have a role in the carbon cycle. Do you know you understand how humans, animals and plants use carbon? This lesson will introduce you to the carbon cycle and explain how it functions on a global scale.

Fossil Fuels, Greenhouse Gases, and Global Warming

3. Fossil Fuels, Greenhouse Gases, and Global Warming

In this video lesson, you'll learn what roles fossil fuels and greenhouse gases play in global warming, as well as what life on Earth can expect due to rising carbon dioxide levels within Earth's atmosphere.

Pollution: Physical, Chemical & Biological

4. 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.

Water Pollution: Definition, Types, and Sources

5. Water Pollution: Definition, Types, and Sources

In this lesson, you will learn about the different types and sources of water pollution. You will gain an understanding of both surface water and groundwater pollution and the similarities and differences between them.

What Is Air Pollution? - Definition, Sources & Types

6. What Is Air Pollution? - Definition, Sources & Types

In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.

The Ozone Layer: Importance and the Harmful Effects of Thinning

7. The Ozone Layer: Importance and the Harmful Effects of Thinning

In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.

Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

8. Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

In this lesson you will learn about two ways humans contribute to species extinction. We break up habitats by building roads and clearing land, and we pollute both land and water. You will also learn about the specific terms used to describe the processes, habitat fragmentation and anthropogenic pollution.

Deforestation, Desertification & Declining Biological Diversity

9. 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.

Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

10. Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

In this lesson, you'll learn how humans overexploit or overharvest species. You will discover the primary way in which humans are responsible for overfishing. You will also learn about how this negatively impacts ecosystems.
