Ch 13: Water, Carbon and Nitrogen Cycles

About This Chapter

Use these video lessons and quizzes to help you understand the water, carbon, and nitrogen cycles. Learn about the cycles of matter and how this applies to human energy needs.

In this chapter, video instructors explain the precipitation, condensation, and evaporation stages of the water cycle. You'll be introduced to other cycles of matter, particularly the nitrogen and carbon cycles. This chapter will discuss photosynthesis and respiration in terms of their relationship to reservoirs of carbon and oxygen.

This chapter explains how the cycles of matter relate to human energy needs and consumption. You'll learn about the advantages and disadvantages of using biomass (organic matter that can be converted to fuel) as a form of renewable energy. As you progress through the chapter, you'll also learn to define fossil fuels and explain the pros and cons of using some typical fossil fuels. When you finish this chapter, you should be able to:

  • Explain the stages of the water cycle
  • Understand the nitrogen and carbon cycles
  • Understand how photosynthesis and respiration affect carbon and oxygen stores
  • Describe the roles of acid rain and fossil fuels in the nitrogen cycle
  • Discuss the pros and cons of biomass and of fossil fuels

Our video lesson instructors strive to make learning the water, carbon, and nitrogen cycles simple. Lessons are short and engaging, using examples you can relate to. Video tags help you navigate through the lessons. Each lesson also includes a transcript, so you can follow along easily, and a brief self-assessment that allows you to track your progress.
