a. Magma type: ________________________________________________________
b. Viscosity: _______________________________________________________
c. Gas content: _______________________________________________________
3. How does the magma type influence a volcanic eruption?
4. Which type of magma is more viscous - basaltic or rhyolitic?
5. What does the gas content relate to in a volcanic eruption?
6. What is an explosive eruption?
7. What is an effusive eruption?
8. Match the eruption type with the description.
a. Explosive eruption
b. Effusive eruption
___ This eruption releases a large amount of gas and ash into the atmosphere.
___ This eruption releases slow-moving lava flows that do not pose a significant threat to nearby populations.
9. What is pyroclastic flow?
10. Diagram the process of volcanic eruption, labeling the key terms and processes involved.
1-2 points: You demonstrated a basic understanding of the concepts. Keep studying and asking questions.
3-4 points: Well done! You have a good grasp of the material.
5-6 points: Excellent work! You have a deep understanding of the concepts and can apply them to real-world scenarios.
1. A volcano is a geological formation that allows molten rock, ash, and gas to escape to the Earth's surface.
2. a. Magma type b. Viscosity c. Gas content
3. The magma type influences the explosiveness of the eruption - more viscous magma results in a more explosive eruption, while less viscous magma results in an effusive eruption.
4. Rhyolitic magma is more viscous than basaltic magma.
5. The amount of gas in a magma chamber relates to the explosiveness of the eruption.
6. An explosive eruption is a volcanic eruption that expels ash, rock, and gas in a violent manner.
7. An effusive eruption is a volcanic eruption that releases lava flows that move slowly and do not pose a significant hazard.
8. a. Explosive eruption b. Effusive eruption
9. Pyroclastic flow is a fast-moving current of hot gas and rock fragments.
10. Diagram will vary. Key terms and processes involved include magma chamber, conduit, throat, vent, crater, lava flow, ash cloud, pyroclastic flow.
Slide Deck Content and Structure
Slide 1: Introduction to Volcanoes
- A volcano is a mountain that can erupt and release hot and molten rock from inside the Earth.
Slide 2: The Major Types of Volcanoes
- There are three major types of volcanoes: shield, cinder cone, and composite.
Slide 3: Shield Volcanoes
- Shield volcanoes are formed from a slow and gentle eruption of lava that flows out of the volcano.
- They are generally low and flat with a wide base and gentle slopes.
- They are called shield volcanoes because they look like a warrior's shield laying on the ground.
Slide 4: Cinder Cone Volcanoes
- Cinder cone volcanoes consist of layers of hardened ash and rock fragments that are blown into the air during a volcanic eruption.
- They are steep and conical in shape with a single vent at the top.
Slide 5: Composite Volcanoes
- Composite volcanoes are formed from a combination of lava flows and explosive eruptions that result in alternating layers of ash, rock fragments, and lava.
- They are tall and symmetrical with steep sides and a pointed peak.
Slide 6: The Formation of Volcanoes
- Volcanoes are formed when magma rises from deep within the Earth's mantle and collects in a magma chamber beneath the Earth's crust.
- As the pressure builds up, the magma forces its way up through a vent or fissure in the Earth's crust, resulting in an eruption.
Slide 7: Volcanoes and Plate Tectonics
- Volcanoes are often found at the boundaries between Earth's tectonic plates, where the plates are either pulling apart or colliding with each other.
- As the plates move, they create tension that can cause magma to rise to the surface.
Slide 8: Interesting Facts about Volcanoes
- The largest volcano in the solar system is found on Mars and is three times larger than Mount Everest.
- The word “volcano” comes from the name of the Roman god of fire, Vulcan.
- Volcanic eruptions can release gases that contribute to air pollution and global warming.
Slide 9: A Relevant Quote
"Eruptions like earthquakes shift life's tectonic plates. Without them, events such as creating mountains, changing ocean currents and generating volcanic, magnetic, and gravitational fields would have taken billions of years, if they happened at all." - Neil deGrasse Tyson
Slide 10: Conclusion
- Volcanoes are fascinating natural wonders that can help us better understand the inner workings of our planet.
- By learning about the major types of volcanoes and how they are formed, we can appreciate and respect these powerful forces of nature.

1. Can you identify the major types of volcanoes within the Earth's crust? These include cinder, shield, and composite volcanoes, which can be identified based on their physical structure and composition.
2. Among the different types of volcanoes, which type typically holds the title for being the largest in terms of size? Is it the cinder volcano, the composite volcano, the shield volcano, or the caldera volcano?
3. What distinguishes a shield volcano from a composite volcano? Is it the volcano's physical shape, the type of lava that erupts from it, its geographical location, or the frequency of its eruptions?
4. There is a specific type of volcano that is characterized by alternating layers of lava, ash, and other volcanic materials. Can you name this volcano? Is it the cinder volcano, the shield volcano, the caldera volcano, or the composite volcano?
5. The formation of certain types of volcanoes can be attributed to the buildup of gas pressure underneath the Earth's surface. Which type of volcano is formed in this way? Is it the cinder volcano, the shield volcano, the caldera volcano, or the composite volcano?
6. Within the Earth's crust, which type of volcano is generally considered to be the smallest in size? Is it the cinder volcano, the composite volcano, the shield volcano, or the caldera volcano?
7. When examining the physical characteristics of a shield volcano, what feature would one most likely observe? Do they generally have steep sides and a narrow base, erupt a mixture of lava and ash, have a caldera at the top, or are they usually found at the edges of tectonic plates?
8. One type of volcano is formed when there is an explosive eruption followed by the collapse of the volcano's summit. What is the name of this type of volcano? Is it the cinder volcano, the shield volcano, the caldera volcano, or the composite volcano?
9. Some types of volcanoes are characterized by specific traits that set them apart from other varieties. For instance, one type of volcano is formed from a single eruption. Can you identify this type of volcano? Is it the cinder volcano, the shield volcano, the caldera volcano, or the composite volcano?
10. Finally, what are some distinct characteristics of a composite volcano? Do they have steep sides and a broad base, only erupt lava, are they generally found in the middle of a tectonic plate, or do they have other distinguishing features?
