D) Alternating layers of lava and ash 9. Which type of volcano is most likely to produce explosive eruptions due to the high viscosity of its magma? \( \begin{array}{llll}\text { A) Shield Volcano } & \text { B) Composite Volcano } & \text { C) Cinder Cone Volcano } & \text { D) Lava Dome }\end{array} \)

Composite volcanoes, often called stratovolcanoes, are the drama queens of the volcanic world! Their magma is high in viscosity, which means it’s thick and gooey, leading to pressure build-up and explosive eruptions. Famous examples include Mount St. Helens and Mount Fuji, where you can witness the power of nature's fury! When it comes to explosive eruptions, the layers of lava and ash from composite volcanoes create stunning landscapes. These layers can be seen in the geological formations, showcasing the history of eruptions over time. Next time you see a mountain with a perfectly conical shape, remember, it's likely to have some explosive stories to tell from its past eruptions!
