What kind of lava flows from Popocatepetl?
Popocat?petl produces a mixture of andesitic and dacite lava in the current cycle of activity. Andesitic, or Basaltic Andesite, is black volcanic rock that contains 55% silica. Dacite, on the other hand, is an igneous, volcanic rock that has a composition that is between Andesite and Rhyolite.
Mount St Helens has layers of this type of rock as well as Andesite through which several domes of Dacite lava have erupted?
Mount St. Helens is known for its layers of volcanic rocks, including basalt and andesite, with eruptions of dacite lava forming domes. These different types of volcanic rocks indicate the diverse magma compositions present beneath the volcano, leading to varying eruption styles and outcomes.
What rock types does the Cotopaxi volcano have?
The Cotopaxi volcano in Ecuador is primarily composed of andesite and dacite rock types. Andesite is a volcanic rock with an intermediate composition between basalt and rhyolite, while dacite has a similar composition to andesite but with more silica content.
What is the composition of Mt Pinatuba?
Mount Pinatubo is composed of andesite, a type of volcanic rock, as well as dacite. It also contains layers of lahar deposits made up of volcanic ash, rocks, and debris from previous eruptions.
What is the composition of magma of popocatepetl?
A mixture of dacite (65wt% SiO2) and basaltic andesite (53wt% SiO2).
Does mt st helens erupt andesite rock?
In some cases, yes. However the most recent eruptions have produced dacite.
What is the difference in composition between a dacite and an andesite?
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.

What type of lava does the composite volcano has?
It varies in composition, but is usually andesite, dacite, or rhyolite.

Do earthquakes make volcanoe eruptions?
a lot
Is mt shasta a explosive or a non-explosive volcano?
Mount Shasta is considered a potentially explosive stratovolcano due to its composition of andesite and dacite lava which can lead to explosive eruptions. However, its most recent eruptions have been relatively non-explosive with mainly effusive lava flows.
What are some extrusive of igneous rocks?
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
What types of igneos rocks are found in Mount Tambora?
Mount Tambora in Indonesia primarily consists of andesite and dacite rocks. These igneous rocks were formed from the cooling and solidification of magma beneath the Earth's surface. Andesite is a fine-grained rock that is intermediate in composition between basalt and rhyolite, while dacite is a fine-grained volcanic rock with a similar composition to andesite but with higher silica content.
