About This Chapter
Biogeochemical Cycles - Chapter Summary
Watch the engaging lesson videos of this chapter to get a refresher on the nitrogen and carbon cycle as well as interactions between the four spheres of Earth. The objective of this chapter is to increase your understanding of the following topics:
- The nitrogen and carbon cycles of matter
- Geosphere, hydrosphere, biosphere and atmosphere
- Interactions between the geosphere, hydrosphere, biosphere and atmosphere
- Difference between renewable and non-renewable resources
These short, engaging lesson videos are taught by expert instructors who are available to answer any questions you may have about the topics covered so that you can master the material. Also don't forget to complete the self-assessment quizzes to fortify your comprehension of the lessons and find areas you don't fully understand. Improve your understanding of these areas by returning to the lesson videos via video tags.
1. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle
Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
2. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere
Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.
3. Interactions of Earth's Spheres: Purpose and Examples
The four spheres of Earth drive all of its processes and support life on our unique planet. In this video lesson, you will see examples of how Earth's spheres interact with each other to form an overall complex and connected system.
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.
