Ch 57: General Science: The Solar System

About This Chapter

In the state of Arizona the NES General Science exam has replaced the AEPA General Science test. As you prepare for the NES General Science exam review this chapter to reinforce your understanding of the formation and characteristics of the solar system.

AEPA General Science: The Solar System - Chapter Summary

As you watch the lessons of this chapter, improve your understanding of the theories about the origins of the solar system, planetary formation, major characteristics of the planets in our solar system and the temperature of our solar system. These lessons are taught by professional instructors and are mobile-device-friendly so that they can be an effective and versatile way of studying the:

  • Solar nebula theory
  • Patterns of planetary motion
  • Condensation sequences of planetary formation
  • Calculations of the age of the solar system
  • Planetesimals and protoplanets
  • Jovian problem
  • Key characteristics of our solar system's planets
  • Temperature of our solar system

For an alternative review of the material, read over the lessons transcripts that offer a written version of the lessons that highlight in bold some of the key terms and figures of this chapter. After you've completed these lessons take the lessons quizzes to test your retention of the material and discover areas of weakness. Improving your understanding of these areas is made easy with video tags that will take you to the locations of the lessons that discussed them.

Test your knowledge with a 30-question chapter practice test
Solar System Overview

1. 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.

The Solar Nebula Theory: Formation of the Solar System

2. 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.

Solar Nebula Theory & Patterns of Planetary Motion

3. Solar Nebula Theory & Patterns of Planetary Motion

This lesson will tie together the solar nebula theory and the patterns of motions of the planets in our solar system and why Venus and Uranus are exceptions in the solar system.

The Condensation Sequences & Planetary Formation

4. The Condensation Sequences & Planetary Formation

In this lesson, you'll learn why the planets have different densities despite being formed from the same solar nebula. We'll cover condensation, uncompressed densities, the ice line, and the condensation sequence.

What is the Age of the Solar System?

5. What is the Age of the Solar System?

This lesson will tell you how old our solar system is and how we know that's the case thanks to radioactive decay, isotopes, half-life, and the solar nebula.

What Are Planetesimals?

6. What Are Planetesimals?

This lesson will define what planetesimals are, how they relate to the solar nebula and protoplanets, and how they interacted with one another to eventually help form the planets in our solar system.

How Do Protoplanets Grow?

7. How Do Protoplanets Grow?

This lesson will teach you about protoplanets, how they formed, and most importantly, how their formation resulted in the planets we see today. We'll also cover outgassing, gravitational collapse, heat of formation, differentiation, and more!

What Is the Jovian Problem?

8. What Is the Jovian Problem?

This lesson goes over the two ways the Jovian planets may have formed, called the core accretion model and disk instability model, as well as the Jovian problem and which model solves it.

Major Characteristics of Planets in the Solar System

9. Major Characteristics of Planets in the Solar System

This lesson will go over some characteristics of the planets in our solar system with respect to their masses, diameters, temperatures, densities, and rotation.

Theoretical vs. Actual Temperature in our Solar System

10. Theoretical vs. Actual Temperature in our Solar System

This lesson will go over the predicted vs. observed temperature of major celestial bodies in our solar system, if there's a discrepancy between them, and why.
