What volcanic eruption type the most violent?
Pelean
What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
What is the most violent type of volcanic eruption?
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
What kind of lava does Mount Shasta have?
What type of eruption does Mt. Shasta have?a composite eruption which is a quiet eruption
What type of eruption does composite volcano have?
The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
quiet nonexplosive eruptionsquiet nonexplosive eruptionsquiet nonexplosive eruptions
Which types of eruptions produce pahoehoe lava?
Pahoehoe is a type of basaltic lava flow. The kind of eruption that causes pahoehoe is a quiet volcanic eruption.
What type of eruption does erebus have?
It's a composite volcano (also known as stratovolcano), which means that it has a big eruption followed by small lava flows. A composite volcano is the deadliest type of volcano and is also the biggest kind.
What type of scientists most likely to study the cooling of lava after a volcanic eruption?
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption
What type of eruptions does Mt Pinatubo have and what causes the eruption to be violent or non-violent?
what causes a eruption to be liolent is the type of lava -felsic lava is non-violent -mafic lava is violent
Why does volcanic ash looks like snow?
It depends on the kind of eruption. In a Hawaiian type eruption parts of the volcano are covered in red hot lava flows and there may be a fountain spewing lava hundreds of feet into the air. In a Strombolian eruption explosions create a firework-like display of airborne lava, which may form lava flows. Some ash may rise from the fountain of lava. In a Vulcanian eruption the volcano produces clouds of ash and sends blocks of rock and globs of lava out at high speeds. In a Pelean eruption the volcano is covered in large clouds of ash. In a Plinian eruption the volcano sends a vertical column of ash miles into the sky to spread out at high altitude. The volcano itself may be covered in clouds of ash.
What shoots out of a volcano during an eruption?
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
