### Educational Content: Seismic Wave Propagation **Diagram Explanation:** The image consists of two main sections: a cross-sectional diagram of Earth's layers and a graph showing wave velocity. 1. **Cross-Sectional Diagram:** - **Lithosphere:** The outermost section of Earth, labeled with a thin arrow pointing to the top left. - **Asthenosphere:** Situated beneath the lithosphere, shown with a gradient color transition, indicating a more ductile layer. - **670-km Phase Transition & 400-km Phase Transition:** Two key transitions marked with arrows at different depths in the mantle. - **Outer Core & Inner Core:** Deeper layers labeled in bright orange and red indicating Earth's core regions. 2. **Wave Velocity Graph:** - **Velocity Scale (km/s):** Ranges from 3 to 12 km/s, located at the top of the graph. - **S-wave Velocity:** Represented by the black curve on the left, which stops at the outer core, indicating that S-waves do not travel through the liquid outer core. - **P-wave Velocity:** Shown by the red curve on the right, which continues through both the outer and inner core. - **Low-velocity Zone:** A region depicted in light pink, indicating reduced speed in the upper mantle. - **Discontinuities:** Areas marked as “400-km discontinuity” and “670-km discontinuity” illustrate changes in wave speeds at these depths. **Question 12:** "In the figure above, what is the approximate speed of S-waves and the P-waves as the earthquake starts?" **Options:** A) 2km/sec and 4km/sec B) 3km/sec and 6km/sec C) 10km/sec and 2km/sec D) 4km/sec and 6km/sec E) 8km/sec and 10km/sec This question assesses the ability to interpret the seismic wave velocities from the diagram. Note when the S- and P-wave velocities are at the Earth's surface, helping determine the correct answer from the options given.

### Earthquake Locations and Plate Boundaries #### Diagram Description The image is a world map showing the locations of five significant earthquakes. Each location is marked with a red dot and labeled with details about the earthquake, including the year, place, and magnitude. 1. **1964 Prince William Sound, Alaska** - Magnitude: 9.2 2. **1952 Kamchatka, Russia** - Magnitude: 9.0 3. **1960 Southern Chile** - Magnitude: 9.5 4. **2004 Sumatra–Andaman** - Magnitude: 9.1 5. **1957 Aleutian Islands** - Magnitude: 8.6 #### Question 11. In the figure above, the largest earthquakes correlate with which type of plate boundaries? - ☐ Convergent (continental - continental) - ☐ Transform plate boundaries - ☐ Divergent plate boundaries - ☑ Subduction zones (continental - oceanic) ### Explanation The map highlights regions prone to major earthquakes, which typically occur in subduction zones where an oceanic plate collides with and moves beneath a continental plate.
