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.

∙ 8y agowhat pushes magma to the surface? the explosion of a volcano is similar to the soda water bubbling out of a warm bottle of a SODA pop. you cannot see the carbon dioxide gas in a bottle of a soda pop because it is dissolved in the liquid. but when you open the bottle the pressure is released. the carbon dioxide expands and forms bubbles dissolved gases are trapped in magma. these dissolved gases are under tremendous pressure.So yeah and then i brush meh hair then brush meh teeth then play with my my little ponies! there so fun!!!!!! Don't forget the soda it's yummy!!!!

∙ 14y agoIt's the pressure built up inside that causes this to happen.

∙ 7y agoThe magma rises because it is under pressure and is usually less dense than the surrounding rock. When it gets close to the surface expanding gasses can make an eruption explosive.

Can dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
No. Dissolved gasses trapped under pressure provide the force.
What burst out of volcano?
When a volcano erupts, the earth is opened up to produce lava, which is magma that has reached the surface. Sometimes, there are materials, or fragments, that are ejected from the volcano by the force of the volcano erupting. These blobs of lava are called Pyroclastic material.
Is a volcano caused by subduction?
Yes, volcanoes usually develop on subduction plate boundaries. The subducting plate pushes up magma to the earth's surface
What provides the primary explosive force that results in a eruption?
The primary explosive force that results in an eruption is the release of built-up pressure in the Earth's mantle. This pressure is caused by the accumulation of magma beneath the surface, which contains volatile gases such as water vapor and carbon dioxide. When the pressure becomes too great, it causes the magma to explosively erupt to the surface, resulting in a volcanic eruption.
What factors determine whether a volcano has a violent or quiet eruption?
A volcano erupts when enough pressure builds up inside of it to unplug it's crater. The stronger the plug, the more force is needed to expel it, which results in a more violent eruption. Also, the stickiness of the lava is a factor. The more sticky the lava, the stronger the eruption.
What force pushes out magma out of a volcano onto the surface?
Pressure.
When you swim what is the force of the water which pushes you toward the surface?
The buoyant force pushes you toward the surface.
What force that forces magma out of a volcano?
Magma erupts out because of immense pressure inside the earth's crust.
Can dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
No. Dissolved gasses trapped under pressure provide the force.
Which force pushes a volleyball out of the water when you attempt to hold it beneath the surface?
buoyancy
Is a spring of heated groundwater that erupts with force from the earth's surface?
Well i don't know why u asking me

Which force changes Earth's surface most slowly?
i think volcano
Why do objects seldom move when forces are applied?
If the object doesn't move, that means there is an opposing force. In that case, the net force on the object is zero. Two typical cases are: * An object resting on a surface is pulled down by gravity. The surface pushes the object up. * In the case of a force that pulls or pushes sideways, the opposing force is usually friction.
What is a contact force between two boxes?
It is an external force that pushes on two boxes in contact on a horizontal surface. You can determine the acceleration of the boxes and the magnitude of the force between them.
What force makes a car begin to move?
1. The forces involved are arise in response to the action of an applied force. 2. Discuss the interaction between an object and a surface it is resting on; the object pushes down on the surface; the surface pushes up on the object with an equal force; this is called the reaction of the surface. 3. Discuss the interaction between two surfaces which slide (or tend to slide) relative to each other; each surface experiences a force in the direction which prevents (or tends to prevent) relative movement; this interaction is called friction.
How does a hydraulic device work?
a hydraulic system multiplies a force by applying the force to a small surface area.the increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area
