Is Mount Rainier an explosive or non explosive volcano why or why not?
It is an explosive volcano. Mount Rainier is a stratovolcano, characterized by layers of ash from explosive eruptions and cooled lava flows from effusive eruptions. The high viscosity and gas content of its magma are the reason for its explosive nature.
What kind of viscosity lava does Mount Tambora have?
High viscosity.
What type of lava does mt rainier erupt?
Much of Mount Rainier is composed of andesitelava flows. Lava flows may accompany explosive eruptive activity, but they occur more often after explosive activity declines. The term "andesite" refers to the chemical composition of the rock. Andesite lavas tend to be moderately viscous and rather slow moving: on gentle slopes, they may move much more slowly than a person can walk.
Does mt.st.helens have a high or low silica content?
Because Mount Rainier is a Strato Volcano it has both quiet and explosive eruptions. Explosive(pyroclastic) flows have a high silica level. Quiet have low silica levels. The more silica the thicker the magma.
Is mount st Helens high in silica or low in silica?
Mount St Helens produces mostly dacite lava, which is relatively high in silica.

What kin d of volcano is mount rainer?
Mount Rainier is a stratovolcano. This means that it is comprised of several layers of hardened rock, lava nad volcanic ash. Mount Rainier is thought to be one of the most dangerous volcanoes in existence.
What will happen if the volcano has high vicosity magma but very low gas content?
The result will be a slow extrusion of lava which will either form a thick block lava flow or a lava dome. If the magma is too viscous it may fail to erupt and instead plug the volcano.
What kind of viscosity lava does Mount Tambora have?
High viscosity.

Low or high viscosity in mount saint Helen's?
The lava in Mt. St Helen has high viscosity.
When Mount Vesuvius last erupted did the lava have high or low viscosity?
High eruption violence.
What type of lava does mt hood have high silica or low silica?
Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
What type of lava is Mount Everest?
Mount Everest has no lava because it is not a volcano
Does Mount Rainier erupt felsic lava?
Like many stratovolcanoes, Mount St Helens has produced material of mafic, felsic, and intermediate composition. Overall, much of the material is itermediate. The 1980 eruption and later activity have produced dacite, which has an intermediate-felsic composition
