Which of the following types of volcanoes has a cauliflower-like shape? (A) Strombolian type (B) Hawaiian type (C) Vulcanian type (D) Pelean type

Vulcanian type volcanoes produce characteristic cauliflower-like ash clouds during eruptions. These eruptions are moderate to violent, involving the explosive release of gas and pulverized rock. The resulting clouds are dark, dense and turbulent, expanding outward as they rise into the atmosphere. This distinctive, billowing shape is caused by the interaction between rising volcanic heat and the surrounding, cooler atmospheric air. ANSWER: (C) Vulcanian type

  1. Vulcanian eruptions are named after the island of Vulcano in Italy. They occur when sticky magma clogs the vent, causing gas pressure to build until it explodes. The hallmark of this eruption is the massive eruption column that looks like a giant cauliflower. This billowing effect happens as the hot, ash-heavy gas surges upward and expands rapidly in all directions. These clouds can reach altitudes of several kilometers and carry large volcanic bombs. The cauliflower appearance is a result of the high-velocity turbulence within the cloud, which carries fine ash and dust across large distances.
