Ch 43: ILTS Biology: Atmospheric Science

About This Chapter

Use our lessons to review facts about topics that include the structure of the atmosphere, the range of conditions organisms will tolerate, causes of climate and types of air pollution as you study for the ILTS Biology exam. These videos are part of a study guide that offers many aids to ensure exam success.

ILTS Biology: Atmospheric Science - Chapter Summary

Use this chapter's lessons to review information about the structure of the atmosphere and rediscover how climates work as you prepare for the ILTS Biology exam. Our videos will help you correctly answer exam questions on the following:

  • Components of the atmosphere
  • Effects of solar radiation
  • The atmospheric cycle
  • Causes of cloud formation
  • Air lift
  • Classifications of climate
  • The harmful impact of a thinning ozone layer
  • Types and causes of precipitation

You can review our lessons at any time by using a computer, smartphone or tablet. The lessons are short, averaging about five minutes, and our instructors make them both entertaining and informational. We provide a written transcript with key terms and concepts highlighted so you can follow along with the video.

ILTS Biology: Atmospheric Science Chapter Objectives

Passing the ILTS Biology exam is one of Illinois' requirements for licensure to teach the subject. This exam has 125 multiple-choice questions, divided into six subareas. The fourth subarea, Earth Systems and the Universe, contains questions on the material covered in our Atmospheric Science chapter.

Like the ILTS Biology exam, the quizzes that accompany each lesson contain only multiple-choice questions. Completing these quizzes will show you what the exam experience will be like. The quizzes also let you test your knowledge of this material and find out where you need additional study.

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.

Organism Tolerance for Atmospheric Conditions

2. Organism Tolerance for Atmospheric Conditions

In this lesson, we'll talk about the different 'comfort levels' that different organisms have for atmospheric conditions. In particular, we'll focus on oxygen levels, but we'll also discuss temperature and other conditions that affect an organism's survival.

What is Solar Radiation? - Definition & Effects

3. What is Solar Radiation? - Definition & Effects

The sun plays an important role to us on Earth. It provides many things such as light and warmth. But, what is solar radiation and how does it affect us? In this video lesson, you'll learn about solar radiation, how it allows us to survive, and the influence it has on our global climate.

Temperature, Clouds, Wind & Humidity on the Atmospheric Cycle

4. 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.

What is Cloud Formation? - Definition, Types & Process

5. What is Cloud Formation? - Definition, Types & Process

There are many different types of clouds that form in the sky. In this video lesson you will learn about how clouds form, as well as the different types of clouds and how they are classified.

Air Lift: Definition & Processes

6. Air Lift: Definition & Processes

In this video lesson, you will learn about air lift. You will also identify the different ways air is lifted, as well as some of the effects each mechanism has.

Climate: Classifications, Distribution & Causes

7. Climate: Classifications, Distribution & Causes

After completing this lesson, you will be able to describe the way that we classify climates, how those climates are distributed across the world, and what factors cause those climates. A short quiz will follow.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

8. 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 Ozone Layer: Importance and the Harmful Effects of Thinning

9. The Ozone Layer: Importance and the Harmful Effects of Thinning

In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.

What is Precipitation? - Definition, Types & Formation

10. What is Precipitation? - Definition, Types & Formation

Precipitation comes in many forms, but it all comes from the same general process. In this video lesson you will identify different types of precipitation, as well as how precipitation forms in the atmosphere from condensation.

What Is Air Pollution? - Definition, Sources & Types

11. What Is Air Pollution? - Definition, Sources & Types

In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.
