About This Chapter

This chapter's video lessons were created to remind you about the different origins and classifications of volcanoes. Refresh your memory of these topics so that you're better-prepared to take the OAE Earth and Space Science examination.

OAE Earth and Apace Science: Volcanoes - Chapter Summary

Study this chapter's lessons in order to review the characteristics of volcanoes and the gases they produce. While you watch the video lessons, you can further explore the functions of volcanic conduits as well as the formation of craters. You'll also get a better idea of the intensity of volcanic hazards, such as lava flow. As you get ready to sit for the OAE Earth and Space Science examination, the lessons in this chapter could help you to:

  • Define and classify volcanoes and explain the origins of the name
  • Discuss various types of volcanoes
  • Describe the formation of volcanic landforms and the effects of released gases
  • Note the distinctions between pyroclastic flow, tephra and pyroclastic surge

Experienced educators present these topics through online video lessons. As long as you have an Internet-connected device, you can brush up anywhere and at any time. Use the video tags to find and study the information you need to review. Corresponding written transcripts and self-assessment quizzes are included in this chapter.

What is a Volcano? - Definition & Eruptions

1. What is a Volcano? - Definition & Eruptions

Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.

Types of Volcanoes: Shield, Cinder Cones & Composite Cones

2. 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

3. 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.

Volcanic Eruption: Gases Released & Their Effects

4. Volcanic Eruption: Gases Released & Their Effects

Volcanic eruptions emit water vapor and toxic gases into the atmosphere. Learn about the gases emitted from an erupting volcano, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid and carbon monoxide and their effects in this video lesson.

Lava Flow, Pyroclastic Flow, Pyroclastic Surge & Tephra: Preventing Volcanic Hazards

5. Lava Flow, Pyroclastic Flow, Pyroclastic Surge & Tephra: Preventing Volcanic Hazards

Volcanic hazards are any type of volcanic process that leads to destruction or threatens life. Learn about specific volcanic hazards including lava flows, pyroclastic flows, pyroclastic surges and tephra and measures used to prevent or reduce damage
