Ch 7: Tectonic Plates, Volcanoes & Earthquakes

About This Chapter

Get all the information you need to perform well on a test that assesses your understanding of tectonic plates, volcanoes and earthquakes. Watching the informative video lessons and taking the short quizzes in this chapter can help you fully comprehend these parts and movements of Earth.

Tectonic Plates, Volcanoes & Earthquakes - Chapter Summary

This chapter offers an entertaining overview of tectonic plates and their movement. The lessons ensure you understand the ins and outs earthquakes and volcanoes. Once you've completed this chapter, you will be ready to do the following:

  • Describe the unifying theory of Earth's surface changes
  • List and describe causes of tectonic plate movement
  • Differentiate between shield, cinder cone and composite cone volcanoes
  • Detail the different types of volcanic landforms and how they form
  • Define and list components of an earthquake
  • Explain what causes an earthquake to occur
  • Discuss the use of seismic activity to identify and understand earthquakes

This chapter offers lessons in two formats: videos and transcripts. The videos let you review the lessons as fun visual presentations, while transcripts offer the option to study the lessons as texts you can read online or print to review at a later time. These lessons are accompanied by mini quizzes you can take to find out how well you understand the topics covered. If you want a broader review of tectonic plates, volcanoes and earthquakes, be sure to take our practice exam.

Plate Tectonics: A Unified Theory for Change of the Earth's Surface

1. Plate Tectonics: A Unified Theory for Change of the Earth's Surface

After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.

Causes of Tectonic Plate Movement

2. Causes of Tectonic Plate Movement

In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull. Students will learn how these processes complement each other and form a theory for tectonic plate movement.

Types of Volcanoes: Shield, Cinder Cones & Composite Cones

3. Types of Volcanoes: Shield, Cinder Cones & Composite Cones

The earth ejects lava, rock fragments, hot vapor and gases during volcanic eruptions. Volcanoes vary based on size, shape, composition and eruptive style. Learn about the different types of volcanoes, such as shield, cinder cone and composite cone.

Volcanic Landforms: Types & Formation

4. Volcanic Landforms: Types & Formation

Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas. Learn about these volcanic landforms and how they are created.

What is an Earthquake? - Definition and Components

5. 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.

The Causes of Earthquakes

6. 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.

Identifying and Understanding Earthquakes Using Seismic Activity

7. 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.
