Do composite volcanoes have high or low silica?
Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
What are three facts about composite volcanoes?
Multiple eruptions form composite volcanoes. Andesite magma is the most common type of magma that erupts from composite volcanoes. Composite volcanoes can grow so high that their slopes become unstable and collapse.
Does a composite volcano have a high gas content?
Yes. Composite volcanoes often have a high gas content in their magma, which is why they often erupt explosively.
Why do composite cone volcanoes with very high viscosity?
um i don't no are you dumb
Does the composite volcano have high viscosity?
Composite volcanoes typically have higher viscosity lava compared to shield volcanoes, resulting in more explosive eruptions. The high silica content in the magma of composite volcanoes contributes to this higher viscosity. However, the exact viscosity of the lava can vary depending on specific factors such as temperature and gas content.
What are the three types volcano?
A shield volcano, cinder cone volcano, and the composite volcano. Shield volcanoes are on of the three types of volcanoes. Shield volcanoes have quiet eruptions and the lava is basaltic. Its slope is shallow compared to a composite volcano and a cinder-cone volcano. They are produced by hotspots and mid-ocean ridge. Cinder-cone volcanoes are the second of the three types of volcanoes. Cinder-cone volcanoes. Cinder-cone volcanoes have explosive eruptions that release lava high in the air. They are created by tephra, volcanic ash. Its slope ranges between 30 degrees and 40 degrees. The lava is andesitic. Composite volcanoes are the third type of volcanoes. Their eruptions vary from loud and explosive to quiet. Composite volcanoes cab rise as high as 8000 feet and are steep. An example of composite volcanoes is Mount Fuji. Composite volcanoes spew felsic lava and they are built up by layers of harden lava, tephra, pumice, and volcanic ash.
Does a composite volcano have silica?
Yes it is high in silica because composite volcanoes are known for being explosive. Composite volcanoes, sometimes referred to as stratovolcanoes, one of Earth's most common type.They form by explosive eruptions of pyroclastic material followed by quieter outpourings of lava. This usually indicates high silica content. High silica makes for thicker magma that can clog up the vent from the volcanoe's last eruption. Which makes the next eruption far more explosive because the magma has to free its self out of the vent, and with tremendous force it succeeds sky rocketing billions of pieces of pyroclastic material out of its vent. (this is known as an explosive eruption.)
Do composite volcanoes have viscous lava?
Volcanoes are named after the lava that comes out.viscous volcanoes (or acid and dome) are the same thing.the lava comes to the surface close to subduction zones,which are found at convergent plate boundaries.it is high in silica content and does not flow easily.it contains gas which cannot escape easily,so eruptions may be explosive and violent.eg Caribbean volcanoes
What is the type of lava in the composite volcanoes?
Composite volcanoes typically erupt with a mixture of lava types, including both viscous lava (andesitic or rhyolitic) that can lead to explosive eruptions, as well as more fluid lava (basaltic) that can flow long distances. This combination of lava types is what gives composite volcanoes their steep-sided profile.
Did AA lava form composite volcanoes?
No, composite volcanoes are typically formed from explosive eruptions caused by viscous lava containing high amounts of silica. A'a lava, on the other hand, is characterized by its rough and blocky texture and typically forms shield volcanoes or cinder cones.
Is plains elevation high or low?
Usually their elevation is low, but sometimes it can be high (for example the highest point in the US High Plains is 7800 ft.).
What does a composite have to do with volcanoes?
Stratovolcanoes or composite volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that gives rise to the name. Stratovolcanoes are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions.
