About This Chapter
Who's it for?
This unit of our Middle School Earth Science Homeschool course will benefit any student who is trying to learn about earthquakes. There is no faster or easier way to learn about the causes and components of these natural disasters. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about earthquake causes, aftershocks and foreshocks, seismic activity, the Richter scale and earthquake destruction.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need an Earth science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and an earthquakes unit exam confirm understanding or identify any topics that require review.
Understanding Earthquakes Unit Objectives
- List the components of an earthquake
- Describe an earthquake's causes
- Explain how seismic activity is used to study earthquakes
- Differentiate between aftershocks and foreshocks
- Relate steps on the Richter scale to earthquake magnitude
- Identify the types of destruction caused by earthquakes
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.
