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
The atmosphere is a protective layer composed of a variety of gases surrounding the entire planet. Discover the major atmospheric components, such as the specific mixture of gasses, the contributions of greenhouse gases, and the ecological significance of the ozone layer.
2. The Structure of the Atmosphere
The Earth's atmosphere is made up of four layers. The one we are most familiar with is the troposphere, which contains the air we breathe, but there are also the stratosphere, mesosphere, and thermosphere. Through the lens of a rocket launching into space, explore the structure and characteristics of the Earth's atmosphere, including where each layer begins and ends.
3. The General Circulation of the Atmosphere
General circulation of the Earth's atmosphere includes the Doldrums, trade winds, high pressure descending air, low pressure rising air, westerlies, and polar easterlies. Explore how the Earth's rotation produces wind cells, and review the general circulation of the atmosphere at the equator and horse latitudes. Learn about the Doldrums, Hadley cell, Ferrel cell, polar front, and polar cell.
4. Pressure: Definition, Units, and Conversions
Talking about pressure is talking about the force per unit area in a container. Learn about the definition of pressure, explore some of the units that are used to express measurements of pressure, and discover how to make conversions among units.
5. Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures
Dalton's Law of Partial Pressures is used to calculate the partial and the total pressures of gases. Explore how gases behave after being mixed together and discover how to apply Dalton's Law to scientific problems concerning water vapor.
6. The Gain or Loss of Atmospheric Gas
The gain or loss of atmospheric gas depends on various factors such as temperature, mass, and velocity. Learn more about the primary and secondary atmosphere, how such factors can affect the atmospheric gas, and the process of atmospheric gas shift.
7. The Atmosphere on Earth
The atmosphere on earth evolved into the current one with a protective ozone layer. Learn about the earth's ancient atmosphere, how the ozone layer has changed, and how human pollution has affected the ozone layer and led to global warming.
8. The Surface & Atmosphere on Mars
The surface and atmosphere on Mars is different from Earth. Learn about the planet Mars and its moons, the Martian atmosphere, the surface of Mars, and water and life on Mars.
9. The Surface & Atmosphere on Venus
The surface and atmosphere on Venus is extremely hot, dry, and rocky. Learn about the planet Venus, the atmosphere of Venus, the surface of Venus, and the subsurface of Venus.
10. The Surface & Atmosphere on Mercury
Mercury, the closest planet to the sun, has a very different surface and atmosphere compared to the Earth's. Learn facts about the planet Mercury, and explore the planet's surface, interior, and atmospheric conditions.
