What else can I help you with?
What forces pushes magma out of a volcano into the surface during a volcano?
it is side vents
How magma moves upward though a volcano and reaches the surface during an eruption?
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
What causes magma beneath the volcano to rise to the surface?
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
What cause an eruption of an volcano?
The amount of pressure that pushes up the magma in a volcano
How does volcanoes from and erupt?
Volcanoes erupt when pressure from inside the earth pushes magma through a weakness in the earth's surface. As more and more magma erupts, the volcano is formed and grows.
Where does the force of an volcano come from?
The force of a volcano comes from the build-up of pressure beneath the Earth's surface due to the movement of magma within the Earth's mantle. When this pressure becomes too great, it can cause an eruption as the magma is expelled through the volcano's vent.
Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
As a volcano erupts what force pushes magma out of a volcano onto the surface?
Pressure does all the work when magma is pushed out of the volcano, because when gasses mix with the lava and certain minerals go into the lava, the heated gasses create a condensed pressure that blows all the lava out of the volcano.
The order of parts through which magma out of volcano onto the surface?
The order of parts through which magma reaches the surface of a volcano is the magma chamber where it accumulates, followed by the central vent or conduit where it travels upwards, and finally the crater or vent at the surface where it erupts and flows out as lava.
How is a volcano born?
A volcano is born when magma from beneath the Earth's surface rises and collects in a magma chamber. As pressure builds, the magma forces its way to the surface through a vent, resulting in an eruption. Over time, repeated eruptions can build up a volcano's cone shape.
Does magma shoot from a volcano or lava?
Magma is lava before it actually reaches the surface of the Earth. So magma comes from a volcano, not lava.
What is the liquid called when the volcano is underground?
It's called magma when it is under the earth's surface. Once it erupts or becomes visible on the surface, its called lava
