These video lessons are available in a flexible online format that allows you to study at your own pace. In addition to the videos, there are also quizzes, transcripts that include key terms and a chapter test that can be useful when you're preparing for test day.
HiSET: The Atmosphere Chapter Objectives
Similar to the GED, the HiSET is a high school equivalency exam that is available in a select group of states. The test includes five separate exams that can be taken in any order. They cover reading, writing, math, science and social studies.
The science portion of the test includes questions in multiple content areas, including chemistry, physics, geology, weather and astronomy. There are 50 multiple-choice questions, and 10 -11 of these are typically related to the Earth sciences (which may include atmosphere-related questions). You can prepare for these questions though our video lessons on 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.
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. 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.
5. 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.
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.
7. 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.
8. 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.
9. 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.
10. 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.
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.
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.
