Ch 19: The Atmosphere: Help and Review

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.

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.

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.

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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.

12. Global Warming: Atmospheric Causes and Effect on Climate

Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.

13. 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.

14. 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.

15. 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.

16. 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.

17. Thermosphere: Definition, Facts, Composition & Temperature

This lesson is about the thermosphere. We will learn what this layer of the atmosphere is, where it is, what it's made of and why it's called the thermosphere.
