How are Cinder Cone volcanoes formed?

By the accumulation of loose and fluid lava flows (correct)

By highly viscous magma with steep upper slopes

By fluid lava that overflows the crater

By layers of magma building up over time

How do caldera complexes differ from other types of volcanoes?

When calderas explode, they collapse over each other creating new depressions instead of increasing the size of the volcano Signup and view all the answers

What distinguishes composite volcanoes from other volcano types?
