The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

2. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.

The Structure of the Atmosphere

3. The Structure of the Atmosphere

If you've ever climbed a mountain or been to the beach, you know that the atmosphere is different at different levels. This lesson explains how the structure of the atmosphere is really like a layer cake.

Formation of the Moon: Theories

4. 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.

Lunar Geology: Types of Moon Rocks

5. Lunar Geology: Types of Moon Rocks

This lesson will discuss the layers of the Moon's interior, the dark and light colored areas of the Moon's surface, the Moon's craters, and how moon dust has formed over the ages.

The Moon's Atmosphere

6. 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.

Moon Phases: Names & Sequence

7. 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.

How Earth & the Sun Affect the Phases of the Moon

8. 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.

Motion of the Moon: Sidereal Month vs. Synodic Month

9. 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.

Predicting When The Moon Will Rise and Set

10. Predicting When The Moon Will Rise and Set

In this lesson, you'll learn when the moon will rise or set during four distinct phases: full moon, new moon, first quarter moon, and third quarter moon.
