Ch 20: Atmospheric Cycle & Solar Energy

About This Chapter

The atmosphere's structure and key components are among the focuses of this chapter. All of the topics in this Atmospheric Cycle & Solar Energy chapter are presented through engaging video lessons.

Atmospheric Cycle & Solar Energy - Chapter Summary

The major variables that affect the weather, such as wind and cloudiness, are examined in this chapter. You'll come across the definitions of solar energy and learn about the the atmospheric effects of Earth's tilt in other lessons. You additionally get to review info on the following:

  • Components and structure of the atmosphere
  • Factors that change the atmospheric cycyle
  • Types of heat transfer, including, conduction, radiation and convection
  • Kinds of greenhouse gases and the Greenhouse Effect
  • Ways that solar radiation is transferred

Video lessons last only 5-10 minutes each. Spread these videos out across bits of free time or watch them back-to-back according to your schedule. Revisit any portions of these videos for additional review with the video tags. The chapter features practice quizzes with each lesson so that you can demonstrate your understanding as you progress through the material.

Major Components of the Atmosphere

1. Major Components of the Atmosphere

Our atmosphere is a complex mixture of many different gases. In this video lesson you will identify the major components of Earth's atmosphere as well as how much there is of each.

The Structure of the Atmosphere

2. The Structure of the Atmosphere

If you've ever climbed a mountain or been to the beach, you know that the atmosphere is different at different levels. This lesson explains how the structure of the atmosphere is really like a layer cake.

Temperature, Clouds, Wind & Humidity on the Atmospheric Cycle

3. Temperature, Clouds, Wind & Humidity on the Atmospheric Cycle

Weather is the current state of the atmosphere and is determined by factors like temperature, pressure and humidity. These factors that cause periodic changes in the Earth's air masses are explored in this lesson.

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.

Greenhouse Gases and the Enhanced Greenhouse Effect

5. 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.

Solar Energy: Effects on Earth's Temperature

6. Solar Energy: Effects on Earth's Temperature

In this video lesson, learn about solar energy and how it affects temperatures on Earth. You will also learn what causes changes in day length and why some parts of Earth experience seasonal differences throughout the year.

Solar Radiation Transfer: Absorption, Reflection & Scattering

7. Solar Radiation Transfer: Absorption, Reflection & Scattering

The sun constantly showers Earth with radiation. Some is absorbed, some is reflected, and some is scattered by the atmosphere. Here, we will explore what happens to this radiation and finish with a brief quiz.
