From what you have learned about the different types of volcanoes‚ how could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples‚ and briefly discuss how some materials may be linked to different types of volcanoes. Volcanoes generally erode away‚ they are not
