Read each question carefully and answer to the best of your ability. For multiple-choice questions, select the best option. For short answer, provide concise and accurate responses.
1. Which type of plate boundary is most commonly associated with both earthquakes and volcanoes?
Divergent boundary
Convergent boundary
Transform boundary
Passive margin
2. What is the primary factor that determines the explosivity of a volcanic eruption?
Volume of magma
Temperature of magma
Silica content and gas dissolved in magma
Depth of the magma chamber
3. The point on the Earth's surface directly above the focus of an earthquake is called the .
4. Volcanic eruptions that produce lava flows with low viscosity typically form volcanoes.
5. The Richter scale measures the intensity of an earthquake, while the Mercalli scale measures its magnitude.
True
False
6. Shield volcanoes are characterized by steep slopes and explosive eruptions.
True
False
7. Briefly explain the concept of plate tectonics and its relationship to earthquakes and volcanoes.
8. Describe the primary differences between an earthquake's focus and its epicenter. Refer to the diagram below.
9. Compare and contrast the characteristics and formation of composite volcanoes (stratovolcanoes) and shield volcanoes. You may refer to the illustration below.
