Questions and Answers

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

    • Which volcano type has relaxed lower slopes and a small crater at its summit?

  • Composite Volcano
  • Caldera Complex
  • Cinder Cone Volcano
  • Shield Volcano (correct)

    • What best describes the formation of a Shield Volcano?

  • Short-lived eruptions with fiery lava fountains
  • Accumulation of layers of magma over time
  • High pressure ejecting fluid lava
  • Slow-moving magma with high levels of gases and silica (correct)

    • Which type of volcano is known for having short-lived eruptions resembling fiery lava fountains?
