Ch 26: Formation & Phases of the Moon

About This Chapter

Check out this chapter's video lessons to review key topics regarding the moon's development and phases. Theories about how the moon was created and the makeup of the lunar atmosphere are discussed.

Formation & Phases of the Moon - Chapter Summary

This chapter covers each of the different phases of the moon along with their sequence. The ways in which our planet and the sun influence these phases are looked at in these lessons. Before completing the chapter, you'll also get to watch videos that explore:

  • The length of the sidereal and synodic months
  • Different kinds of lunar eclipses
  • Conditions allowing for lunar and solar eclipses to happen
  • How the moon causes tides
  • The definition of tidal friction

These videos can be viewed on various handheld devices in addition to computers. Video tags let you pinpoint any segments that you'd like to revisit after your initial review. Take the self-assessment quizzes matched up with each lesson across the chapter to make sure you have a solid grasp of the issues.

Formation of the Moon: Theories

1. Formation of the Moon: Theories

Explore the four major theories on the formation of the Moon. The theories include the fission theory, capture theory, condensation theory and giant impact theory. Also look at both information supporting and flaws found in these theories.

The Moon's Atmosphere

2. The Moon's Atmosphere

This lesson will go over the lunar atmosphere, its composition, where it gets it atmosphere from, how it may lose its atmosphere, and what the technical term for the lunar atmosphere is.

How Earth & the Sun Affect the Phases of the Moon

3. 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.

Moon Phases: Names & Sequence

4. 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.

Motion of the Moon: Sidereal Month vs. Synodic Month

5. 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.

Lunar Eclipse: Definition & Types

6. 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.

How Can We Predict An Eclipse?

7. How Can We Predict An Eclipse?

This lesson will tell you when lunar and solar eclipses are possible, what nodes have to do with it, how long eclipse seasons last, and what the Saros cycle is.

How Gravity, the Moon & the Sun Influence Tides

8. 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.

Tidal Friction: Effects on Earth & the Moon

9. 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.

What Is a Solar 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.
