In this lab, you will explore how differences in tectonic setting result in volcanoes with different types of magma, and therefore different eruptive styles, landforms, and hazards. You will compare and explore the differences between stratovolcanoes, caldera-type eruptions, cinder cones and shield volcanoes. Plate Tectonic Setting Use the Dynamic Planet Map in lab, or Figure 1.6, page 4 in your textbook to locate volcanoes and plate boundaries. Notice that volcanoes also occur where there are no plate boundaries.
Hot spots can also occur under continents - Yellowstone is a nearby example.
For the volcanically active plate boundaries that you identified above, and for the hot spot locations listed below, identify the type of rock that melts, and the characteristics of the magma. Click on each to see definitions. Shield volcano Caldera Stratovolcano Cinder cone Flood basalt 2. Shield volcanoes, flood basalts and cinder cones are all composed of basalt. Each of these eruptions leaves behind a very different volcanic landform.
