Who's it for?
This chapter of our earth science tutoring solution will benefit any student who is trying to learn about volcanoes and earn better grades. This resource can help students including those who:
- Struggle with understanding types of volcanoes, pyroclastic flow, volcanic hazards or any other volcanoes topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their volcanoes unit
- Cope with ADD or ADHD
- Want to get ahead in earth science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about volcanoes simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live earth science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about volcanoes on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Discuss the nature of volcanoes and volcanic eruptions.
- Identify the three major types of volcanoes.
- Name the main gases released during a volcanic eruption.
- Describe the flow of pyroclastic materials.
- Explain how volcanic landforms form.
- Discuss the different types of volcanic hazards and explore ways to prevent these hazards.
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.
8. Composite Volcano: Definition, Facts & Examples
The earth is not a quiet place, covered with plates in constant motion. Volcanoes come in all shapes and sizes, depending on where and how they have formed. In this lesson, we will look at composite volcanoes, including how and where they form, and where on earth they can be located.
9. Pumice: Definition, Uses & Facts
Learn about pumice, an extrusive volcanic igneous rock with a unique vesicular texture and a wide variety of uses, from beauty products to construction materials. After you have watched the video, test yourself with the quiz questions.
10. What is a Landslide? - Definition, Causes & Facts
Think you know what a landslide is? Did you know there are different kinds? Here you will learn how landslides differ, why they happen, and where they are most likely to occur.
11. Stratovolcano: Definition, Formation & Facts
This lesson covers one of the most dynamic natural features on earth - the stratovolcano. In this lesson, learn how they form, what makes them tick, and the eruptions they produce.
12. Volcanic Deposits: Definition & Explanation
Discover what happens to the landscape after a volcano erupts. Learn how deposits from volcanoes create mountains, islands and even precious minerals.
13. What Are Volcanoes? - Eruption, Types & Facts
Explore volcanoes, from the fiery explosion of Mount St. Helens to the slow-flowing lava on Hawaii's 'Big Island.' Learn about how volcanoes form and how they are classified.
14. What is a Dormant Volcano? - Definition, Facts & Example
Did you know some volcanoes can ''sleep'' for thousands of years while others erupt at regular intervals? In this lesson, we will learn why some volcanoes can wait long periods of time before erupting. We will also look at some examples of dormant volcanoes.
