Does Mount St Helens lava flow violently or quietly?
Lava can't flow violently. Highly explosive eruptions such as the 1980 eruption of Mount St. Helens do not produce lava flows: they produce clouds of ash, gas, and pumice. Mount St. Helens has produced "quiet" lava flows at times.
Do water based paint spray areas require explosion proof fixtures?
No, they do not. No explosive fumes are produced.
What created when alkaline earth metals and water combined?
When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.
What type of lava flow did mt st helens have?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was a plinian eruption that produced aolumn of ash and pyroclastic flows. Pyroclastic flows are avalanche-like masses of hot ash, rock, and gas that rase away from an erupting volcano at speeds that can reachinto the hundreds of miles per hour.
What type of flow does mt st helens have?
Mount St. Helens has produced lava flows in the past. However, the famous eruption in 1980 produced something much more dangerous: pyroclastic flows. These are avalanche-like currents of hot ash, rock, and gas that race out of a volcano. The initial pyroclastic flow from the lateral blast may have briefly been supersonic.
Can non explosive volcanoes have pyroclastic flows?
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
What does tephara mean?
"Tephra" refers to fragments of volcanic rock, ash, and other material ejected during a volcanic eruption. These fragments can vary in size from ash particles to large blocks. The term is often used in volcanology to describe the material that is produced during explosive volcanic activity.
Are pahoehoe and AA are produced during explosive eruptions?
Pahoehoe comes from an explosive eruption, whereas AA comes from quiet eruptions.
Are Mount St Helen's eruptions quiet or explosive?
Mount St Helens has produced both quite and explosive eruptions. It is best known for a very large explosive eruption in 1980.
Is the Yellowstone volcano quiet explosive or both?
Yes. The Yellowstone volcano has produced several VEI-8 eruptions, the most explosive level of eruption possible.
What kind of eription is produced when basaltic lava that is low in silica flows from a volcan?
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
Is mt vesuvius a quiet eruption or explosive?
The 1980 eruption was very explosive. Ash was blown 80,000 feet into the air and the mountain is a quarter mile shorter than it was before the eruption.
Is mount st helens explosive or nonexplosive?
Mount St. Helens is known for its explosive eruptions. In 1980, it erupted violently and produced a massive explosive eruption that caused significant devastation to the surrounding area. Subsequent eruptions have also been explosive in nature.
What is the name of the cloud that volcanos make when they erupt?
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
Is mount tambora an explosive volcano?
No, Mt. Stromboli is a very active Volcano.
What do you call the fast-travelling stream of hot gas and fragmental material that is produced during an explosive volcanic eruption?
Pyroclastic flow
When Mount Pinatubo erupted it caused lava flow?
No. The 1991 eruption of Mount Pinatubo was a highly explosive Plinian eruption. Instead of lava flows it produced a massive column of ash and pyroclastic flows.
