Is mount Krakatoa a shield volcano?
No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.
Does a composite volcano erupt quietly or explosively?
A composite volcano is the most explosive type of volcano there is. Mt. St. Helens and Mt.Vesuvious in Pompeii are both examples of composite volcanoes, and look at the damage they did. a composite volcano usually has pyroclastic flows to accompany the traditional lava and ash.
Cinder cones are the most dangerous volcanoes?
Cinder cones are typically small volcanoes that have short and relatively mild eruptions compared to larger composite volcanoes or stratovolcanoes. While they can erupt with explosive force, their eruptions are usually confined to the immediate area surrounding the cone and do not pose as much risk to human populations as other types of volcanoes.
Where are composite volcanoes usually found-?
in the north pole during the winter months.
Why are the eruptions of stratovolcanoes usually more destructive than the eruptions of shield volcanoes?

What kind of volcanoes form along subduction zones?
Composite or stratovolcanoes typically form along subduction zones. These volcanoes are characterized by their steep-sided profile, explosive eruptions due to the presence of viscous magma, and alternating layers of lava flows and volcanic ash. Subduction zones are where one tectonic plate slides beneath another plate, leading to magma formation and volcanic activity.
What kind of mafic lava do composite volcanoes have?
Composite volcanoes usually do not erupt mafic material. Intermediate material is the most common. The mafic material they do erupt is usually basalt.
Do composite cone volcanoes have mafic lava?
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
What kind of you eruptions do composite volcanoes make?
Composite volcanoes can contain a wide variaty of magmas ranging from basaltic to rhyolitic.
Compare shield volcanoes to composite volcanoes?
A shield volcano is made from lava flows that flow far, making a very wide, not very steep mountain. A cinder cone volcano is the most common type of volcano. It is formed from volcanic fragments and is very steep sided, although not always extremely tall. They usually have just one main vent, and can also sometimes form from a vent of a larger volcano, growing and becoming a whole new volcano. Composite volcanoes resemble very large cinder cone volcanoes at first, but have bigger particles making them up usually and also have multiple vents more often. They also are potentially more explosive.
What are the similarities and differences between the types of volcanoes?
Shield volcanoes have fluid basaltic flows that are lower in silicates, making the lava very fluid without a tendency to form pyroclastics. Composite Cone volcanoes contain the highest percentage of silica content making the magma thicker with the greatest tendency to form pyroclastics and are the most dangerous volcanoes.
