What else can I help you with?
What determines the frequency and types of eruptions you can expect from a volcano?
The crystal and gas content and temperature of a magma help determine a volcano's eruption style. • Crystals in magma make it more viscous, so magma with a high crystal content is more likely to explode than flow. • Gases create explosions if they cannot easily escape from viscous magma, but they can also be released without explosions (or with only minor ones) from fluid magma. • High-temperature magmas usually erupt effusively, while low-temperature magmas cannot flow easily and are more likely to erupt explosively.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
How many types of magma are there?
their are many types of magma because when a volcano has soft magma that means it either exploded small or the magma was going really slow and fast magma and big exploding volcano's are hard magma.:)
Which type of volcano sometimes erupts violently due to the intense pressure that builds up when the vent becomes sealed by thick magma?
A stratovolcano, also known as a composite volcano, can erupt violently due to the buildup of pressure from thick magma. The thick magma can block the vent, leading to explosive eruptions as the pressure is released. These types of eruptions often result in ash clouds, pyroclastic flows, and lahars.
What is the difference of an active volcano and a dormant volcano?
An active volcano is one which maintains a hot magma chamber, so that it might erupt anytime in the future. An inactive (extinct or dormant) contains mainly cooled lava and is not likely to erupt unless there is a new supply of hot magma.
Type of mountain where magma breaks the surface?
The type of mountain where magma breaks the surface is a volcano. Their are three types of volcanos, composite, shield, and cinder cones.
Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt

WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.

What determine the type of volcano?
Its magma composition.different types of volcanic eruptions form different types of volcanoes
What cause volcano to eurption?
Volcanoes erupt due to the build up of magma (rocks are cooled magma which is made liquid by intense heat) in the Earth's crust below the place they erupt. This is called seismic activity. Some types of volcanoes are: New ones which erupt sometimes after other thermal activity becomes apparent sometimes unexpectedly but usually in an area where there are other volcanoes or thermal activity. An example is the Volcanic Plateau in New Zealand which is part of the Pacific Rim of Fire where many extinct, dormant and active volcanoes are situated. Other volcano types are: extinct, nothing happening for a very long time dormant, they have not erupted for a long time but might become active in 500-1000 years active, they 'dribble or spew' all the time
What types of volcanoes are created when andesitic magma erupts?
Andesitic magma will result in the formation of a stratovolcano, also called a composite volcano.
Why eruption of each volcano different?
Different types of volcanoes erupt differently due to different compositions of the magma chambers as well as differnt magma types being present within the volcanoes. The three main types of magma are Basalt, Andesite, and Rhyolite. These erupt in very different manners.Basalt - Basalt eruptions are ften known as Hawaiian style eruptions, they are categorized by curtains of fire and long rift zones. The magma itself is very fluid in nature, it does not readily trap gasses to explosive levels and therefore has very placid and erupts in flows and layers. Volcanoes of this type are known as shield volcanoes.Andesite - This is an intermediate magma in its viscosity, it will flow but not as well as basalt does. This magma also has the ability to trap dissolved gasses to explosive levels. It is an intermediate viscosity and a volcano of this type would be a stratovolcano or cinder cones.Rhyolite - The most viscous basic form of magma, it does not want to flow and will build into lava domes around active vents. This magma is known for its ability to drive very powerful explosions through its ability to maintian dissolved gas and only let it escape through explosive decompression. A volcano of this type can be a Stratovolcano or a Caldera.
