Composite Volcanoes – Structure, Example, Formation and Life Cycle
Composite Volcanoes: Composite volcanoes, also referred to as stratovolcano, are a type of volcano that has a distinctive shape and also eruptive characteristic. These volcanoes are tall, steep-sided cones and are formed through a combination of both explosive as well as effusive volcanic activity. Let us understand more about the structure, eruptive behavior, formation, and characteristics of composite volcanoes.
