Ch 12: Understanding the Earth's Atmosphere

About This Chapter

To help you solidify your understanding of the atmosphere of the Earth, we've put together this engaging and mobile-friendly chapter. The short and professionally designed lessons and self-assessment quizzes here are meant to assist you as you prepare for an upcoming exam.

Understanding the Earth's Atmosphere - Chapter Summary

In this chapter, we've provided short lessons on understanding the Earth's atmosphere for you to review at your convenience. Here you'll study greenhouse gases, mechanisms of heat transfer and global wind patterns, among other related topics. Once you complete this chapter, you should be ready to:

  • Outline the components and structure of the Earth's atmosphere
  • Detail the seven major regions of the electromagnetic spectrum
  • Discuss greenhouses gases and the enhanced greenhouse effect
  • Define conduction, radiation and convection as mechanisms of heat transfer
  • Identify the global wind patterns of the three wind belts
  • Provide the definition and impact of insolation
  • Explain weather fronts and air masses
  • Differentiate between the carbon cycle and the nitrogen cycle

Feel free to work at your own pace and review these lessons as many times as needed to feel comfortable with this material. Testing your knowledge is easy using the quizzes provided with the lessons and the comprehensive test at the end of the chapter. Any questions that come up along the way can be submitted to one of our instructors through the Dashboard.

Test your knowledge with a 30-question chapter practice test
Earth's Atmosphere: Components & Structure

1. Earth's Atmosphere: Components & Structure

After completing this lesson, you will be able to describe the layers of Earth's atmosphere, what they contain, and the components (gases) that make up the atmosphere. A short quiz will follow.

The 7 Major Regions of the Electromagnetic Spectrum

2. The 7 Major Regions of the Electromagnetic Spectrum

This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.

Greenhouse Gases and the Enhanced Greenhouse Effect

3. Greenhouse Gases and the Enhanced Greenhouse Effect

In this video lesson, you will learn about the five main greenhouse gases and how their unnaturally high concentrations are leading to the enhanced greenhouse effect and global climate change on Earth.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

4. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

The Global Wind Patterns of the Three Wind Belts

5. The Global Wind Patterns of the Three Wind Belts

You are familiar with wind, but did you know there are different wind belts depending on where you are on the earth? This lesson will examine the three main wind belts: polar easterlies, tropical easterlies and prevailing westerlies.

Insolation: Definition, Global Wind Patterns & Impact

6. Insolation: Definition, Global Wind Patterns & Impact

Insolation is the amount of incoming solar energy over an area per unit of time, which is unevenly distributed on the Earth. In this lesson, we will explore how insolation creates global wind patterns and affects the climate in a particular region.

Air Masses and Weather Fronts

7. Air Masses and Weather Fronts

After completing this lesson, you will be able to explain what an air mass is and how the movement of weather fronts leads to weather patterns you see every day.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

8. 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.
