Question
### Understanding Earthquake and Plate Tectonics The following questions aim to deepen your comprehension of key geological concepts related to earthquakes and plate tectonics. 1. **The distribution of earthquakes defines the boundaries of which major Earth feature?** *Answer:* 2. **Deep-focus earthquakes are associated with what prominent ocean-floor feature?** *Answer:* 3. **Along what prominent ocean-floor features do shallow-focus earthquakes occur?** *Answer:* 4. **Why do Earth scientists think that rigid slabs of the lithosphere are descending into the mantle near the Tonga islands?** *Answer:* 5. **Describe how paleomagnetism is used to calculate the rate of seafloor spreading.** *Answer:* 6. **Based on your calculations in [Activity 3.7B](#), what are the rates of seafloor spreading for the following ocean basins?** - **North Atlantic basin: _____ cm/yr** - **Pacific basin: _____ cm/yr** *Answer:* 7. **Based on your calculations in [Activity 3.7C](#), what are the ages for the North and South Atlantic basins at the locations examined?** - **North Atlantic basin: _____ million yr old** - **South Atlantic basin: _____ million yr old** *Answer:* 8. **Based on your calculations in [Activity 3.8](#), what is the maximum velocity for the Pacific plate?** - **_____ cm/yr** *Answer:* 9. **Complete the block diagrams in [Figure 3.12](#) to illustrate the types of plate boundaries listed below each diagram. Include arrows to indicate relative motion.** *Explanation:* In [Figure 3.12](#), the diagrams illustrate different types of plate boundaries, including: - **Divergent boundaries:** where plates move apart. - **Convergent boundaries:** where plates move towards each other. - **Transform boundaries:** where plates slide past each other horizontally. Use labeled arrows to show the direction of plate movement for each type of boundary. ### Conclusion These questions and activities will help you understand the relationship between earthquake activity and plate tectonics, as well as the methods used to study seafloor spreading and plate movements. Completing the associated activities and diagrams will provide a comprehensive understanding
