What else can I help you with?
Is the core of a volcano a magma chamber?
Yes.. the only do if its extinct im a proffeser btw
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.
When lava breaks through the earth's crust?
that is a volcano starting 100 years would pass and then it becomes more of a 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.
Can a mountain become a volcano or viceversa?
Yes, a mountain can become a volcano if tectonic activity causes magma to rise and erupt through the surface. On the other hand, a volcano can also become a dormant or extinct mountain over time if there is no longer any active magma movement.
What is a constructive boundarie?
At a constructive plate boundary two plates move apart. As they move apart the magma from the magma chamber flows up to fill the gap. This causes a volcano. However, as the magma can escape easily it flows down the volcano with only a little bit of force. So it has a gentle erupt.

Do volcanoes have to be a specific type of rock for lava not to melt through?
No. Some melting of rock occurs in and under a volcano from the magma, but it is only a small fraction of the volcano's rock. There are two reasons for both stemming from the first law of thermodynamics: energy can neither be created nor destroyed, only converted between different forms. This means that for magma or lava to heat up and melt a rock, the lava itself must cool down. In terms of temperature, the magma in a volcano is closer to solidifying than the rock is to melting. Second, the volume of solid rock in a volcano is much larger than the volume of magma.
If a tall shield volcano has been built by many eruptions over thousands of years the magma that helped build the volcano contained?
a lot of silica and only a little water vapor
What makes a volcano scary?
Imagine your at the bottom of a volcano. The volcano has just erupted and the magma is oozing out turning to lava and headed toward your house. The lava looks like its going slow but you only have a couple minutes to get out. Would you be scared in this situation?
When metamorphic rock melts turns into?
Metamorphic rock that melts turns to magma. This only becomes lava if it is erupted to the surface in a volcano.

How does a volcano stop erupting?
As far as i know, I believe that the plate of earth underneath that's spitting out the lava has a little time limit going over it. Any volcano can erupt from a couple seconds to maybe even a couple minutes. ~Mega :]
Is lava and magma the same?
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
