Let's match the words in Column A with their corresponding descriptions in Column B step by step. ### Column A and Column B 1. **Circumpacific Belt** - **Match:** G. location where crustal plates are weak - **Explanation:** The Circumpacific Belt, also known as the "Ring of Fire," is an area where many tectonic plates meet, leading to volcanic and seismic activity. 2. **Crust** - **Match:** B. first layer of the earth - **Explanation:** The crust is the outermost layer of the Earth, where we live. 3. **Earthquake** - **Match:** A. shaking and trembling of the ground - **Explanation:** An earthquake is characterized by the shaking of the ground due to seismic waves. 4. **Epicenter** - **Match:** I. area above where the earthquake originates - **Explanation:** The epicenter is the point on the Earth's surface directly above the focus of an earthquake. 5. **Intensity** - **Match:** F. refers to the effects of the earthquake - **Explanation:** Intensity measures the effects of an earthquake at different locations. 6. **Magnitude** - **Match:** E. amount of energy released by an earthquake from its focus - **Explanation:** Magnitude quantifies the energy released at the source of the earthquake. 7. **Tectonic earthquake** - **Match:** D. caused by the movement of the earth's crust - **Explanation:** Tectonic earthquakes occur due to the movement of tectonic plates. 8. **Volcanic earthquake** - **Match:** C. happens with a strong volcanic eruption - **Explanation:** Volcanic earthquakes are associated with volcanic activity and eruptions. 9. **Seismograph** - **Match:** H. used to detect earthquakes - **Explanation:** A seismograph is an instrument that measures and records the motion of the ground during an earthquake. 10. **Focus** - **Match:** J. break in the ground caused by pressure of the moving rocks - **Explanation:** The focus (or hypocenter) is the point within the Earth where an earthquake originates, often associated with a fault line. ### Summary of Matches 1. Circumpacific Belt - G 2. Crust - B 3. Earthquake - A 4. Epicenter - I 5. Intensity - F 6. Magnitude - E 7. Tectonic earthquake - D 8. Volcanic earthquake - C 9. Seismograph - H 10. Focus - J This completes the matching activity!
