Ch 41: MTEL Biology: Environmental Pollution

About This Chapter

The Environmental Pollution chapter goes over the human causes of eutrophication for part of its content. The chapter's videos and transcripts cover a number of other topics that could appear on the MTEL Biology exam.

MTEL Biology: Environmental Pollution - Chapter Summary

Lessons about environmental problems associated with groundwater such as overdrawing will give you an effective review of material you've already learned and may even have some new information. Other issues this chapter goes into that will give you more review for the MTEL Biology exam include:

  • Chemical, biological and physical pollution
  • Sources and types of water pollution
  • Activities that affect the water supply
  • Habitat destruction and eutrophication
  • Overexploitation issues, such as overfishing
  • Human factors in endangerment and extinction
  • Cultural differences based on geography and climate
  • Air pollution and measures for controlling it

You'll also see a refresher lesson that highlights the differences between physical, chemical and biological pollutants with examples. The short and fun videos throughout have video tags you can use to pinpoint any specific focus areas.

MTEL Biology: Environmental Pollution Chapter Objectives

The questions on the MTEL Biology exam about information in the Environmental Pollution chapter will be on the last multiple-choice subarea on the exam: Populations, Ecosystems and the Environment. The environmental pollution content covered in this chapter's text and video lessons could be seen in any of the relevant exam subarea's 16 to 18 questions. The open-response questions that come after the Populations, Ecosystems and the Environment subarea may also ask about the material that's in this chapter, as well. The Environmental Pollution chapter lets you see questions that look similar to MTEL Biology items with its practice quizzes.

Pollution: Physical, Chemical & Biological

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.

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

2. 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.

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

3. 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.

Geography and Climate: Effects on Civilizations

4. Geography and Climate: Effects on Civilizations

In this lesson, we will look at the relationship between geography, climate, and civilization. We will learn why civilizations develop in particular regions and how this leads to lifestyle and cultural differences.

Water Resource Issues: Activities Affecting the Water Supply

5. Water Resource Issues: Activities Affecting the Water Supply

This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.

Human Causes of Eutrophication

6. Human Causes of Eutrophication

Eutrophication occurs when a body of water becomes overly enriched with nutrients. While this can happen naturally, accelerated eutrophication is typically the result of human activities. Learn about the human causes of eutrophication.

Environmental Problems Associated With Groundwater

7. Environmental Problems Associated With Groundwater

Groundwater is an important natural resource, but like many of our other resources, it's affected by the surrounding environment and human activities. In this video lesson, you'll learn about some of the environmental problems associated with groundwater and why groundwater is especially vulnerable to them.

Water Pollution: Definition, Types, and Sources

8. 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

9. 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.

Controlling Air Pollution: How Developed & Developing Nations Differ

10. Controlling Air Pollution: How Developed & Developing Nations Differ

In this lesson, you will learn how air pollution is controlled in developed and developing nations. You will also learn about the U.S. Clean Air Act and how it has evolved over the years to address air pollution in the United States.
