About This Chapter
Understanding Earthquakes - Chapter Summary
The interactive quizzes and engaging video lessons in this chapter will help middle school students review information on earthquakes, including the definition, causes, and components of an earthquake. The comprehensive video lessons will also address seismic activity, foreshocks and aftershocks, the Richter scale, and the destruction that earthquakes can cause. The videos can be replayed as many times as your student needs to fully grasp each concept, and they also feature an interactive timeline that allows students to jump to specific topics.

1. What is an Earthquake? - Definition and Components
Earthquakes are well known for the damage and destruction they leave behind. But what is an earthquake? In this video lesson you will learn about what causes earthquakes and the various components involved in these powerful natural disasters.
2. The Causes of Earthquakes
In this video lesson you will learn what causes earthquakes and where they occur. You will also understand the theory of elastic rebound, and how this relates to movement of the earth's crust.
3. Identifying and Understanding Earthquakes Using Seismic Activity
Scientists can learn a lot about earthquakes by studying how they move ground. Using seismic activity, we can learn where an earthquake originated as well as how strong it was. In this video lesson, you will learn about seismic activity and how it relates to our understanding of earthquakes.
4. Aftershocks & Foreshocks of an Earthquake
An earthquake is not an isolated event of ground shaking. Foreshocks and aftershocks occur with most earthquakes, and in this video lesson you will learn about them and how they are part of the overall process.
5. Using the Richter Scale to Measure Earthquakes
In this video lesson, you will learn about earthquake magnitude and how it is measured. You will also learn how that relates to the amount of energy released during an earthquake, as well as how common different magnitude earthquakes are around the world.
6. Destruction Caused by Earthquakes
Earthquakes are well-known for their damage and destruction, and in this video lesson you will learn about the different types of damage that these dangerous natural disasters can cause.
