Read each question carefully and provide thoughtful answers. Refer to your knowledge of volcano types and geological processes.
Observe the diagram below illustrating different types of volcanoes.
1. Which type of volcano is characterized by its broad, gently sloping sides and effusive eruptions of low-viscosity lava?
Stratovolcano
Shield volcano
Cinder Cone volcano
Caldera
2. What is the primary cause of explosive eruptions in stratovolcanoes?
Low silica content in magma
High water vapor content in magma
High viscosity of magma trapping gases
Rapid cooling of lava
3. A large, basin-shaped depression formed when the roof of a magma chamber collapses after an eruption is called a .
4. Cinder cone volcanoes are typically built from pyroclastic fragments that accumulate around a vent, forming a relatively steep-sided, -shaped hill.
5. Shield volcanoes are known for their violent, explosive eruptions due to highly viscous magma.
True
False
6. Stratovolcanoes are also known as composite volcanoes because they are built up by layers of hardened lava and tephra.
True
False
7. Compare and contrast the eruption styles of shield volcanoes and stratovolcanoes. Include details about magma viscosity and gas content.
8. Describe the formation of a caldera. What geological events lead to its creation?
Match each volcano type with its characteristic description.
9. Shield Volcano
a. Formed by explosive eruptions of pyroclastic material.
10. Stratovolcano
b. Broad, gently sloping cone built from fluid lava flows.
11. Cinder Cone
c. Steep-sided cone composed of alternating layers of lava and ash.
