About This Chapter
Volcanic Landforms - Chapter Summary
Volcanoes are among the many amazing landforms found on Earth. But while they are beautiful in appearance, we all know the dangers they pose when they erupt. Learn more about volcanic landforms by reviewing the short lessons in this chapter. Prepared by top instructors, these lessons provide the insights you need to correctly identify types of volcanoes, explain how they erupt and more in your science course. To gauge your comprehension of the lessons, take short multiple-choice quizzes and a chapter exam. If you have questions about any lesson concepts, be sure to submit them to our experts. Topics covered in this chapter include:
- Differences and similarities between three types of volcanoes
- Gases released and other effects of volcanic eruptions
- Volcanic landforms and their formation
- Types of volcanic hazards
1. 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.
2. 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.
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.
4. 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
