What is the composition of Mount Rainier?
Mount Rainier is composed mainly of andesite lava flows, lahars (mudflows), and volcanic ash. The mountain is also covered by glaciers which contribute to its iconic snow-capped appearance.
What type of lava does Mount Rainier have Aa or Pahoehoe?
Mount Rainier primarily has andesitic lava, which can exhibit characteristics of both Aa and Pahoehoe types. However, the predominant lava flows associated with Mount Rainier are typically more akin to Aa, as they are often cooler and more viscous, resulting in a rough, jagged surface. Pahoehoe, which is smoother and more fluid, can occur but is less common in this region.
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
What type of lava forms mt rainer?
Mount Rainier is composed primarily of andesite lava, which is an intermediate type of lava that has a higher silica content compared to basaltic lava. This type of lava is more viscous, leading to explosive eruptions and the formation of volcanic cones like Mount Rainier.
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 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.
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.
Is mt rainer a cinder cone volcano?
Mount Rainier is not a cinder cone volcano. It is a stratovolcano, also known as a composite volcano, which is characterized by alternating layers of lava and ash. Stratovolcanoes like Mount Rainier are typically larger and more explosive than cinder cone volcanoes.
What type of volcano is Mount Rainier like a shield volcano but different?
Mount Rainier is a stratovolcano, which is different from a shield volcano in that it is made up of layers of different types of lava and ash, creating a steeper profile. Shield volcanoes, in contrast, have a broad, gentle slope primarily made up of basaltic lava flows.
What type of lava does mt rainier erupt?
Mount Rainier is a stratovolcano that typically erupts andesitic lava, which is a viscous type of lava that can lead to explosive eruptions. This lava tends to build up pressure before erupting, creating the potential for large ash clouds and lahars.
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 type of cone or shape does mt hood have?
where will i get this stupid answer? really you guys useless idiots
What kind of viscosity lava does Mount Tambora have?
Mount Tambora typically produces highly viscous lava due to its high silica content. This results in the lava being thick and slow-moving, leading to more explosive eruptions.
Which type of lava does mount Eyjafjallajokull have?
probably basaltic lava because the 2010 eruption was very explosive
