PANGANGAN NATIONAL HIGH SCHOOL Lomboy, Calape, Bohol ACTIVITY SHEET NO. 2 Name: Score: Year and Section: Date: Subject: SCIENCE Type of Activity: Activity/Exercises Activity Title: Let’s Mark the Boundaries Learning Target: Describe the distribution of active volcanoes, earthquake epicenters, and major mountain belts. Determine the scientific basis for dividing the lithospheric plates. References: Title: Science 10 Learner’s Materials Page Numbers: 11 – 14 Materials: • Figure 5: Map of earthquake distribution • Figure 6: Map of active volcanoes of the world • Figure 7: Mountain ranges of the world • 2 pieces plastic sheet used for book cover, same size as a book page • marking pens (two different colors) Figure 5. Map of earthquake distribution (Red, green, and blue dots represent earthquake epicenters) Procedure: 1. Study Figure 5 showing the earthquake distribution around the world. Trace the approximate locations of several earthquake “clusters” using a marking pen on one of the plastic sheets. Figure 6. Map of active volcanoes (Red areas represent presence of volcanoes) 2. Study the map of active volcanoes in Figure 6. 3. On the second plastic sheet, sketch the approximate locations of several volcanoes using a marking pen. 4. Place the earthquake plastic sheet over the volcano plastic sheet. Figure 7. Mountain ranges of the world 5. Study Figure 7, the orange portions indicate mountain ranges of the world. 6. Now that you have seen the location of volcanoes, mountain ranges, and majority of earthquake epicenters, study Figure 2 on page 7, Map of Plate boundaries once more. The places on Earth where most of the earthquakes originated or some mountains and volcanoes were formed mark the boundaries of each lithospheric plate. As mentioned earlier, each plate is slowly moving relative to each other, causing geologic events to happen along their boundaries. Exercises: Q1. How are earthquakes distributed on the map? Q2. Where are they located? Q3. Where are there no earthquakes? Q4. Why is it important for us to identify areas which are prone to earthquakes? Q5. How are volcanoes distributed? Q6. Where are they located? Q7. Based on the map, mention a country that is unlikely to experience a volcanic eruption. Q8. Compare the location of majority of earthquake epicenters with the location of volcanoes around the world. Q9. How will you relate the distribution of mountain ranges with the distribution of earthquake epicenters and volcanoes? Q10. What do you think is the basis of scientists in dividing Earth’s lithosphere into several plates?
