| What major natural events are described in Quaking Earth, Racing Waves? | Earthquakes and tsunamis (racing waves) |
| Who is one scientist mentioned in the text who works to understand earthquakes? | Kerry Sieh |
| What technique did scientists use when “reading the corals”? | They examined coral growth patterns to infer past sea levels and tectonic movements. |
| What causes an earthquake, according to the text? | Movements of Earth’s tectonic plates and shifts along faults. |
| Why can’t people feel the regular, slow movements of tectonic plates on Earth’s surface? | Because those movements are gradual and very slow, they don’t produce enough force for people to sense. |
| What is the difference between a tsunami and a normal ocean wave? | A tsunami is caused by undersea earthquakes and involves much more water moving deeply and powerfully, while a normal wave is surface motion (wind-driven). |
| How do underwater shifts in land lead to racing waves (tsunamis)? | When a portion of the sea floor suddenly moves, it displaces huge volumes of water, sending waves racing outward. |
| What evidence do scientists use to try to predict earthquakes? | Patterns in coral growth, fault movements, historical seismic activity, and stress accumulation on plates. |
| What advice does Kerry Sieh give to people who live south of Tello? | He advises them to prepare for earthquakes, have emergency plans and be aware of warning signs. |
| What is the central idea of Quaking Earth, Racing Waves? | That although we cannot predict earthquakes with precision, scientists study Earth’s movements to better understand them and help communities prepare. |
| How does the author use domain-specific (scientific) vocabulary in the text? | Words like “tectonic plates,” “fault,” “displacement,” “tsunami” help make the science clear and rigorous. |
| What is the author’s purpose in writing this text? | To inform readers about how earthquakes and tsunamis occur and how scientists study them. |
| Identify one challenge scientists face when trying to predict earthquakes. | Uncertainty in timing and magnitude, incomplete historical record, or complex Earth dynamics. |
| How do coral formations act like a “record” of Earth’s history? | Corals grow layer by layer responding to sea levels; changes in growth patterns reflect uplift or subsidence events. |
| In what ways does the text show that Earth is dynamic, not static? | Shifts in plates, sudden movements, rising/falling land, tsunamis — all evidence of change. |
| What effect do racing waves (tsunamis) have on coastal areas? | They can flood, destroy structures, erode coastlines, and cause loss of life and property. |
| How does the author connect past events to present-day risk for people? | By discussing past earthquakes and tsunamis and linking them to preparedness in modern communities. |
| What role does monitoring and observation play in earthquake science, as shown in the text? | Continuous measurement and watching for changes help refine models and warnings. |
| What can a reader infer about the importance of community preparedness from the text? | That while we can’t control earthquakes, being ready (education, plans, early warning) can reduce harm. |
| What evidence from the text shows that scientists are cautious in their predictions? | They refer to estimates, patterns, probabilities, and avoid claiming certainty — they emphasize preparation and warning instead of absolute predictions. |
