About This Chapter

Review basic meteorology concepts with this comprehensive study resource. The chapter includes lessons on the Earth's atmosphere and different types of weather systems, such as thunderstorms and hurricanes.

Basics of Meteorology - Chapter Summary

This helpful collection of lessons can help you review the basics of meteorology. As you progress through the chapter, you'll study concepts such as the Earth's atmosphere, the atmospheric cycle, clouds and wind. The chapter also covers the causes and formation of several types of weather phenomena, including thunderstorms, tornadoes and floods. You can also look at different types of weather maps. Upon completion of this chapter, you'll be able to:

  • Describe the structure of the Earth's atmosphere
  • Understand the effects of atmospheric pressure
  • Know how temperature, clouds, wind and humidity relate to the atmospheric cycle
  • List the causes, characteristics and properties of wind
  • Identify types of cloud formations
  • Determine how different types of weather fronts affect weather
  • Analyze weather maps and images
  • Explain how thunderstorms are formed
  • Recognize the causes of tornadoes, hurricanes and floods
  • Measure humidity
  • Define precipitation

These lessons simplify the learning process by presenting essential meteorology definitions and concepts into bite-sized chunks. Each lesson is taught by a subject-matter expert, and you can use the accompanying self-assessment quizzes to make sure you've fully grasped the information you've learned. If you need to review a specific concept, quickly jump to that topic using the video tags in the Timeline. Lesson transcripts are available to print for further study.

The Structure of the Atmosphere

1. 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 Atmosphere on Earth

2. The Atmosphere on Earth

This lesson describes the evolution of the Earth's atmosphere, from its ancient past to the present day to how it's being changed by humans today. You'll learn about how outgassing, photosynthesis, and oceans all played a role in its formation, what air is composed of, and the real effect of human pollution on our changing atmosphere.

Atmospheric Pressure: Definition & Effects

3. Atmospheric Pressure: Definition & Effects

Atmospheric pressure is around us all of the time. The air you are breathing has weight, and although it doesn't weigh a lot, there is a lot of it around. This lesson will cover atmospheric pressure and its effects.

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 Wind? - Definition, Causes, Properties & Characteristics

5. What is Wind? - Definition, Causes, Properties & Characteristics

Wind is an important phenomenon that we have all experienced. In this lesson, you'll learn more about the definition, its causes, and characteristics. Then, test your knowledge with a quiz.

What is Cloud Formation? - Definition, Types & Process

6. 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.

Understanding Weather Fronts: Types & Their Effect on Weather

7. Understanding Weather Fronts: Types & Their Effect on Weather

In this video lesson you will learn about how air masses with different characteristics create weather fronts. You will also identify the different types of fronts, as well as what type of weather occurs along them.

Types of Weather Maps & Images

8. Types of Weather Maps & Images

Ever think that weather forecasters just make up their predictions? While they don't always get it right, weather forecasters have a great deal of information at their disposal, as this lesson demonstrates.

What Are Thunderstorms? - Definition, Types & Formation

9. What Are Thunderstorms? - Definition, Types & Formation

Thunderstorms are common all over the world. In this video lesson, you will learn what they are, how they form and how they create thunder and lightning.

What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

10. What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

Tornadoes are dangerous storms that affect millions of people. In this video lesson, you will learn how and where they form, as well as how scientists classify tornadoes using the Enhanced Fujita Scale.

Hurricanes: Types, Formation, Causes & Effects

11. Hurricanes: Types, Formation, Causes & Effects

Hurricanes are dangerous storms that affect millions of people each year. But what are hurricanes and how do they form? In this video lesson you'll learn about where and how hurricanes develop as well as the types of hurricanes that are possible.

What Are Floods? - Causes, Types & Prevention

12. What Are Floods? - Causes, Types & Prevention

In this video lesson, you will study floods, their causes and their effects. You will learn to identify various methods that are used to prevent floods and explore how preventing natural flood cycles can lead to dangerous flood events.

What is Humidity? - Definition, Measurements & Effects

13. What is Humidity? - Definition, Measurements & Effects

Humidity is an important aspect of the atmosphere because it affects both weather and climate. In this video lesson you will learn about the different types of humidity and understand how temperature affects water vapor in the air.

What is Precipitation? - Definition, Types & Formation

14. 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.
