What is the primary characteristic of a stratovolcano?

• It is small and forms from tephra.

• It has a broad base and is formed from fluid lava.

• It is steep-sided and constructed from layers of lava and ash.

• It only erupts once.

Cinder cone volcanoes are primarily made up of what material?

• Basaltic lava

What is the main difference between a shield volcano and a stratovolcano?
