About This Chapter
Who's it for?
This unit of our AP Environmental Science Homeschool course will benefit any student who is trying to learn about volcanic formation and hazards. There is no faster or easier way to learn about volcanoes. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about the effects of gases released during volcanic eruptions.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need an environmental 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 a volcanoes unit exam confirm understanding or identify any topics that require review.
Volcanoes Unit Objectives:
- Get the definition for a volcano and learn about volcanic eruptions.
- Discuss landslides and tsunamis.
- Study the flow of pyroclastic materials.
- Discuss composite cones and cinder cones.
- Examine methods for preventing volcanic hazards.
- Learn about lava flow and pyroclastic surge.
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.
