Ch 20: TASC Science: Weather & Climate

About This Chapter

The components of the atmosphere, climate classification and the four spheres of Earth are some of the many topics you'll see discussed in this chapter's lessons. Our Weather & Climate chapter helps you prepare for the TASC Science exam through engaging videos and text lessons.

TASC Science: Weather & Climate - Chapter Summary

Gain familiarity with the different weather patterns and ocean circulation with the short videos and lesson transcripts in this study guide. The Weather & Climate chapter also goes into the following material to help you prepare for the TASC Science test:

  • The structure and main components of the atmosphere
  • The Earth's spheres
  • Major climate classifications and where they are found
  • Factors of regional climate
  • Patterns of ocean circulation
  • The differences between weather and climate
  • General circulation of the atmosphere
  • Air mass types and their effect on weather
  • Sources and types of air pollution
  • Greenhouse gases and the greenhouse effect

There are numerous bolded key terms in the transcripts that help you find the chief lesson points quickly. These key terms also are likely to be seen in some of the chapter's practice questions that you can complete for self assessment.

Objectives of the TASC Science: Weather & Climate Chapter

TASC Science is one of the five TASC subject area tests used to examine your content knowledge toward earning a high school equivalency credential. The test's questions are mostly multiple choice, with the paper-based and computer-based formats each having close to 50 multiple-choice questions. You will also see a constructed-response type question with each test format, and the computerized version has an additional technology-enhanced item. The Earth and space sciences subarea is where you will see questions dealing with the topics in this Weather & Climate chapter; this subarea makes up 28% of the total test questions.

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.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

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.

Interactions of Earth's Spheres: Purpose and Examples

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.

Climate Classifications & Their Global Distribution

5. Climate Classifications & Their Global Distribution

Earth has many climates, but we can categorize them based on common characteristics. In this video lesson you will identify the 5 major climate classifications on Earth, as well as where on Earth these climates are found.

Natural Factors That Determine a Region's Climate

6. Natural Factors That Determine a Region's Climate

Climate is influenced by factors like atmosphere, ocean currents, landforms and plate tectonics. This lesson explains how these effects affect our weather patterns, which determine climate.

Ocean Circulation: Patterns & Effect on Climate

7. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Weather vs. Climate: Definition, Differences & Effects

8. Weather vs. Climate: Definition, Differences & Effects

This video lesson will guide you in understanding the difference between climate and weather. Discover how they are different but related and how they are the ways you can describe atmospheric conditions on Earth.

The General Circulation of the Atmosphere

9. The General Circulation of the Atmosphere

The Sahara Desert, tropical rainforests, and cold polar winds are all due to Earth's rotation. In this video lesson, you will learn how this rotation has created global air circulation patterns on Earth and how it is responsible for such diverse climate patterns across the globe.

Types of Air Masses & Their Effect on Weather

10. Types of Air Masses & Their Effect on Weather

Air masses affect weather in a number of different ways. In this lesson, you will learn about the different types of air masses found on Earth and how the movement of air masses creates changes in the weather.

Greenhouse Gases and the Enhanced Greenhouse Effect

11. 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.

What Is Air Pollution? - Definition, Sources & Types

12. 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.
