About This Chapter
Plate Tectonics Theory - Chapter Summary
Study the basics of plate tectonics theory without setting foot in a traditional classroom. Our online lessons make it easy to explore or refresh your knowledge of sea floor spreading, mid-ocean ridges and subduction from home or on-the-go. Once you've completed this chapter, you will be able to:
- Define and list components of plate tectonics
- Share the theory of and facts about sea floor spreading
- Explain the relationship between polar reversal and sea floor spreading
- Describe the formation of mid-ocean ridges
- Detail the process of subduction
- List different types of mountains and explain how they form
- Discuss how the geological progression of a landscape is described through a landform diagram
- Make calculations to describe the motion history of geological features

1. What is Plate Tectonics? - Definition, Theory & Components
Imagine ice floating in a glass. Would you believe that we are all living on giant pieces of floating rock, just like the ice in that glass? This lesson explains that theory, an idea known as plate tectonics.
2. Sea Floor Spreading: Definition, Theory & Facts
The continents are on the move and sea floor spreading helps to explain how. Here you will learn what sea floor spreading is, how it works, where it is happening, and what led to its discovery.
3. Sea Floor Spreading and Polar Reversal
Sea floor spreading is the process by which new oceanic crust is formed by the upwelling of magma through diverging tectonic plates. Learn about the relationship between sea floor spreading and polar reversals detected on the ocean floor.
4. Mid-Ocean Ridge: Definition, Facts, Formation & Example
Mid-ocean ridges...on the surface, it sounds obvious what these might be, but there are complicated forces that create them. Here, you will learn what mid-ocean ridges are, where they are, how they are created, and what makes them fascinating geological formations.
5. Subduction: Definition & Process
Subduction is a geological term for one of Earth's tectonic plates sinking under another. When this happens, we can get earthquakes, volcanoes, and a recycling of Earth's rocks. Let's explore this more in this lesson.
6. The Processes of Mountain Building
In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.
7. How a Landform Diagram Describes the Geological Progression of a Landscape
This lesson describes what a landform diagram is. We'll also discuss some basic laws of geology that can help scientists deduce both the order of events that create a landform and the geologic events that occur after a landform's formation.
