Which type of volcano has a steep sided cone from layers of ash and lava flow from all sides?

• composite volcano

• cinder cone volcano

• shield volcano

Which type of volcano has gentle sloping sides from slow lava flow?

• composite volcano

• cinder cone volcano

• shield volcano

Which type of volcano erupts violently but very rarely.

• composite volcano

• cinder cone volcano

• shield volcano

How does a cinder cone volcano shape the earth?

• It causes the build up of a volcanic mountain over time.

• It causes the formation to grow to tremendous heights because the lava cools and hardens before spreading.

• It shapes the earth becasue it spews lava into the air which falls back to earth and hardens.
