Students will review:
This chapter helps students review the concepts in an Atmosphere on Earth and Other Planets unit of a standard Intro to Astronomy course. Topics covered include:
- Major components of the atmosphere
- The structure of the atmosphere
- Defining and describing atmospheric pressure
- The general circulation of the atmosphere
- Pressure: definition, units and conversions
- Dalton's law of partial pressure
- The gain or loss of atmospheric gas
- The atmosphere on Earth
- The surface and atmosphere on Mars
- The surface and atmosphere on Venus
- The surface and atmosphere on Mercury
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. 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.
4. Pressure: Definition, Units, and Conversions
Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.
5. Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures
In this lesson, you will learn how gases behave when they are mixed together and how to use Dalton's law of partial pressures to calculate partial and total pressures of gases. You will also learn how to use this information to explain how to find the partial pressure of a gas collected over water.
6. The Gain or Loss of Atmospheric Gas
This lesson will discuss how a planet's atmosphere is formed, how it is shaped by the planet's characteristics, and how it evolves with time. Afterwards, you can take a short quiz to test your knowledge of planetary atmospheres.
7. 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.
8. The Surface & Atmosphere on Mars
One little mistranslation spawned generations worth of theories about life on Mars. But is there any real evidence for the possibility of life on Mars? What is the Martian atmosphere and surface really like? Can it support life? Find out in this lesson.
9. The Surface & Atmosphere on Venus
This lesson will discuss the terrible atmosphere located on Venus, as well as its surface features and how the planet differs from Earth's geologic processes.
10. The Surface & Atmosphere on Mercury
This lesson will describe the planet Mercury's surface components and how they came to be as the planet formed. It will also go into the planet's interior and atmosphere.
