Lab Activity: Life on the Edge of the Plates

I. Purpose/Objective: Students will map out the locations of various earthquakes and volcanoes throughout the world. II. Standards Addressed: Earth Science 3a, 3b, 3c, 3d, 3e III. Hypothesis: Describe the location of volcanoes and earthquakes in relation to tectonic plate boundaries. IV. Materials: world map, color pencils V. Procedure 1. Make a color key for earthquakes and volcanoes on your map. 2. Using the latitude and longitude coordinates for the earthquakes and volcanoes label their location on the map using their corresponding letter. 3. Determine the locations of the mountain ranges on the map and write out their names on their specific locations. VI. Data Volcano Longitude Latitude A – Aconcagua 70W 35S B – Tungurahua 80W 0N C – Pelee 61W 15N D – Tajumulco 90W 15N E – Popocatepetl 100W 20N F – Lassen 122W 40N G – Rainier 122W 47N H – Katmai 155W 60N I – Fujiyama 139E 35N J – Tambora 120E 10S K – Krakatoa 108E 5S L – Mauna Loa 155W 20N M – Kilimanjaro 37E 3S N – Etna 15E 38N O – Vesuvius 14E 41N P – Teide 16W 28N Q - Laki 20W 65N

Analysis Questions 1. Which ocean has a ring of volcanoes around it? 2. In relation to the tectonic plate edges, where are most of the volcanoes located? 3. Which volcanoes are not located on the edge of a tectonic plate? 4. Describe the general relationship between the earthquake regions and the tectonic plates. 5. Describe the general relationship between mountain ranges and the tectonic plates. 6. Are all the earthquakes listed found along the edges of tectonic plates? Explain.

VII. Conclusion What is the purpose/objective for this activity? How does you hypothesis compare to the actual locations of most volcanoes and earthquakes? What do you think causes the volcanoes and earthquakes in those locations? What do you think causes volcanoes or earthquakes in the center of a tectonic plate?
