About This Chapter
The Sun-Earth-Moon System - Chapter Summary
These video lesson cover the interactions of the Sun-Earth-Moon system, including how the Earth and sun affect the phases of the moon and the sequence of the moon phases. After completing this chapter, you should be able to:
- Differentiate between the different motions of the moon
- Discuss the effects of the Earth's revolution and rotation
- Explain how the moon, sun, and gravity sun influence tides
- Understand tidal friction and how energy moves in the sun
- Define a lunar and a solar eclipse
- Identify the structure of the sun
- Describe the Babcock Model of the sun's magnetic cycle and the stages of the sun's life cycle
The short video lessons give you an in depth look at the topics in this chapter, and our expert instructors make learning fun. The video tags allow you to go back and re-watch key points in the video, and the quizzes allow you to check your understanding. Stay organized by checking your dashboard as you go through this chapter and the course.
1. Interactions in the Sun-Earth-Moon System
Learn how the sun, earth, and moon interact with each other to create tides, phases, eclipses, seasons, solar winds, and precession. Take a quiz and see how much you've picked up.
2. 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.
3. Moon Phases: Names & Sequence
This lesson will go over the phases of the moon. The full moon, new moon, waxing, waning, and gibbous phases and the order in which they occur and what they look like are discussed.
4. Motion of the Moon: Sidereal Month vs. Synodic Month
This lesson will teach you about the sidereal month and synodic month, how long they are, and how they are measured with respect to the stars and sun.
5. Effects of the Earth's Rotation & Revolution
This lesson explores the factors that influence seasons, daylight, and temperatures on our planet, including rotation and radiation. At the end, you can test your knowledge with a brief quiz.
6. 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.
7. Tidal Friction: Effects on Earth & the Moon
This lesson will go over the concept of tidal friction, why it occurs, and how all of that has affected Earth's spin and day length, as well as the moon's rotation and distance from Earth.
8. How Energy Moves Within the Sun
This lesson will describe how energy is carried from the inner reaches of the Sun, through the radiative zone, then the convective zone, and finally into space.
9. Lunar Eclipse: Definition & Types
This lesson will teach you about the lunar eclipse. You'll learn the difference between a penumbral, partial, and total lunar eclipse, and see what totality means with respect to a total lunar eclipse.
10. What Is a Solar Eclipse?
This lesson will describe what a solar eclipse is, why it's possible, when a partial or a total one will occur, and what cool effects occur during one.
11. Structure of the Sun
Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.
12. The Babcock Model of the Sun's Magnetic Cycle
This lesson will cover a model called the Babcock model or Magnetic-Dynamo model, which helps to explain how many of the features of the solar and sunspot cycle occur.
13. Stages of the Sun's Life Cycle
Discover our sun, the provider of energy for life on Earth. Learn how the sun was born, how it lives as a main sequence star, how it will age into a red giant and how it will die as a white dwarf.
