About This Chapter
Who's it for?
Anyone who needs help learning or mastering introductory astronomy material will benefit from taking this course. There is no faster or easier way to learn introductory astronomy. Among those who would benefit are:
- Students who have fallen behind in understanding the layout and formation of the solar system
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the solar system's formation
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Formation of the Solar System chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Formation of the Solar System chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any question about the formation of the solar system. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students will review:
This chapter helps students review the concepts in a formation of the solar system unit of a standard intro to astronomy course. Topics covered include:
- Solar nebula theory
- Condensation sequences and planetary formation
- Growth of protoplanets
- The layout of the solar system
- Gravity and the solar system
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.
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.
3. 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.
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.
5. 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.
6. 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!
7. 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.
8. 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.
9. 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.
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.
11. Albedo: Definition, Effect, Equation & Measurement
Albedo helps determine the temperature of the Earth and also affects the weather. In this lesson, learn about albedo, its effects on the climate and weather, and how to measure it.
12. Planetesimal: Definition, Theory & Hypothesis
Planetesimals are small rock fragments that combined together to eventually form planets. This lesson will discuss the theory behind planet formation and the importance of planetesimals. After the lesson, there will be a quiz to test your knowledge.
