About This Chapter
Cycles and Spheres of Earth - Chapter Summary
Get a quick review of the main elements and macronutrients making up living organisms before exploring the various ways in which these molecules are cycled through the environment. Our experienced instructors walk you through the interactions between the hydrosphere, geosphere, biosphere, and atmosphere. Lessons in this chapter can also help you examine the following topics:
- Phosphorus cycle
- Nitrogen cycle
- Carbon cycle
- Earth's four spheres
This brief chapter includes video lessons lasting less than ten minutes each, transcripts with key terms in bold, and self-checking quizzes to help determine when you've mastered these chapter topics. Plus, you can access any and all of these resources at your convenience, wherever you take your mobile device.
1. Biogeochemical Cycling and the Phosphorus Cycle
In this video lesson, we'll take a look at how elements large and small use other elements to grow. This is achieved through cycles. We'll look at macronutrients, trace elements and the biogeochemical and phosphorous cycles.
2. 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.
3. 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.
4. 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.
