About This Chapter
Components of the Solar System & Universe - Chapter Summary
The lessons in this chapter offer an opportunity to refresh your knowledge of the structure of the solar system and the universe. These videos provide an overview of the makeup of the solar system, including a theory on how it was formed.
You'll see how phases of the moon work and also examine the causes of tides. Another lesson explores ideas about how the universe grew right after its birth. By the time you've watched all these lessons, you should know more about topics such as:
- Structure of the solar system
- The planets
- The solar nebula theory
- How the Earth and sun influence the moon's phases
- The influence of gravity, the sun and the moon on tides
- Theories on how the early universe expanded and developed
These short lessons are taught by experts who know how to make learning fun. You can contact them through our message board if you have questions. Every lesson is followed by a short quiz, and the chapter ends with a comprehensive exam. A video timeline in each lesson makes it easy to click over to a specific point in the video for review. There's also text transcript of every lesson with key terms and concepts highlighted for you.
1. What is a Solar System? - Planets & Model
The solar system consists of all the matter that lies within the gravitational pull of the sun. This lesson will describe the formation of the solar system along with the objects in it. At the end there will be a quiz to test your knowledge.
2. Solar System Overview
This lesson will go over the major aspects of our solar system, including the sun, planets, moons, asteroids, comets, meteors, meteorites, and meteoroids.
3. The Solar Nebula Theory: Formation of the Solar System
This lesson will go over the theory that explains how the solar system formed, what theory had once competed with it, and what important implication this theory carries.
4. How Earth & the Sun Affect the Phases of the Moon
This lesson will describe how the moon, Earth, and sun combine to form the phases of the moon. We'll also discuss the important concept of synchronous rotation.
5. How Gravity, the Moon & the Sun Influence Tides
This lesson will define tides, the tidal force, neap tide, and spring tide. It will also talk about how the sun, moon, and Earth interact to produce tidal bulges.
6. The Evolution of the Early Universe
This lesson will describe four important stages of development in the early universe, the radiation era, recombination (decoupling) epoch, the dark age, and reionization era.
