About This Chapter
Below is a sample breakdown of the Volcanoes chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Definition and types of volcanoes||Nature of volcanic processes, types of volcanoes, including composite cones, cinder cones and shield volcanoes; consideration of composition, size, eruptive style and shape|
|Tuesday||Volcanic eruption||Role of gases and study of gases released during a volcano, including sulfur dioxide, water vapor, carbon dioxide and nitrogen|
|Wednesday||Flow of pyroclastic materials||Discussion of welded tuff, ash, dust, scoria and pumice; dangers of pyroclastic flow|
|Thursday||Volcanic landforms||How volcanoes are formed; types of volcanic landforms, including craters, necks, lava plateaus, calderas, volcanic pipes and fissure eruptions|
|Friday||Volcanic hazards and prevention||Hazards such as lava flows, volcanic earthquakes, lahars, volcanic gases, landslides, debris avalanches and pyroclastic flows; prevention methods|
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.
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.
3. 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.
4. The Flow of Pyroclastic Materials
A pyroclastic flow is the flow of volcanic ash, gases and fragments following a volcanic eruption. Learn about the types of pyroclastic flows and the materials that make them up and contribute to their fluid nature.
5. 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.
6. 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
7. Volcanic Hazards & Prevention: Landslides, Lahars & Tsunamis
Volcanic hazards are any volcanic process that can damage property or threaten life. Learn about volcanic hazards, such as landslides that can trigger lahars and tsunamis, and ways to prevent these hazards from threatening people's lives.
