What else can I help you with?
If granite within earth melts and then erupts at the surface what type of extrusive rock is likely to form?
If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
This type of volcano erupts with some degree of regularity?
A stratovolcano is a type of volcano that erupts with some degree of regularity due to its composition of thicker, more viscous lava. This viscosity can lead to pressure build-up and explosive eruptions, causing periodic activity.
What factors influence whether a volcano erupts explosively?
the concentration of AA in the magma
What magma is called after it erupts above ground?
Magma is called lava once it erupts above ground. Lava is molten rock that flows from a volcano during an eruption.
A volcano that no longer erupts is said to be?
Dormant.
What type of magma does mount Pinatubo have?
Mount Pinatubo primarily erupts dacitic magma.
How often does mt Pinatubo errupt?
It erupts every 500 years or so.
What is material with granitic composition that erupts at Earth's surface?
Material with a granitic composition that erupts at the surface is called rhyolite.
Mt Pinatubo will erupt in the near future?
yes,actually every volcano erupts on the right time
Could Mt Pinatubo will erupt in the near future?
yes,actually every volcano erupts on the right time
What type of eruption did mount Pinatubo have?
Mount Pinatubo had LATERAL eruption. It means, generally volcano erupts at its highest peak where its vent finds an opening, but mount Pinatubo got a weak side and therefore it erupted laterally.
How do you use catastrophe in sentence?
"The end of the world describes the Earth's catastrophism."
How often does mount Pinatubo erupt?
Mount Pinatubo erupts on an irregular basis, about every 3,000 to 5,000 years. The last big eruption began in 1991.It typically will erupt multiple times during an eruption period before going dormant again.
What lava flow does Mount Pinatubo have?
Mount Pinatubo is most famously known for its 1991 eruption, which resulted in a massive column of ash and volcanic materials being expelled into the atmosphere. This eruption did not involve a lava flow, but rather a pyroclastic flow, which is a mixture of hot ash, gas, and rock fragments that surged down the slopes of the volcano at high speeds.
What is mt vesuvius composition?
Mount Vesuvius' magma is comprised mostly of pumice stone. It is low density molten rock that erupts at a high temperature.
How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What is mount etna magma composition?
Mount Vesuvius' magma is comprised mostly of pumice stone. It is low density molten rock that erupts at a high temperature.
