Correct option is A
- A. Pelean type: The Pelean type eruptions are characterized by extremely viscous lava with a violent eruption (IV). This type of eruption typically produces pyroclastic flows.
- B. Hawaiian type: Hawaiian eruptions are known for more fluid basaltic lava which is effusive and quiet in nature (I). This type of eruption generally involves lava fountains and lava flows.
- C. Strombolian type: Strombolian eruptions have less fluid basaltic lava and are known for their explosive nature (II), with short bursts of gas and lava.
- D. Vulcanian type: Vulcanian eruptions are characterized by viscous lava that does not remain liquid after contact with air, making the eruptions more explosive and violent (III).
Information Booster:
- Pelean eruptions are known for pyroclastic flows and are very explosive due to the high viscosity of the lava.
- Hawaiian eruptions, which are typically the least violent, involve more fluid lava that travels easily, creating lava flows.
- Strombolian eruptions are moderate and explosive, often producing lava bombs and short-lived eruptions.
- Vulcanian eruptions have very viscous lava that leads to explosive eruptions, often involving pyroclastic material.
- Different types of volcanic eruptions are influenced by the lava's viscosity, which determines the eruption's intensity and behavior.
