What period of time is from 250-500 million years ago? What is a composite volcano and give an example? How do explosive eruptions affect the earth? What time period are we in now? How old is the earth? describe two of the three types of volcanoes: Include: Type of explosion What the volcanoes look like how the explosion affects the area an example of each volcano 10. What does a non-explosive eruption look like?
