Why do valcanoes erupt?
A volcano is formed by pressure building up below the Earth's crust. Magma forces it way through weaknesses in the earth's crust. When the magma emerges it is called lava. When it cools, it solidifies into rock,or it may emerge though thin cracks,which are called fissure.Or it may be forced though wider pipes,that starts to build up, to a volcano.
Does lava erupt because of the heat?
NO, it erupts because of the build-up of pressure in the magma containment. When the pressure becomes so strong that there is no other way to release it, the lava rushes up and blows off the top of the volcano.
What provides the force that causes magma to erupt to the surface?
The force that causes magma to erupt to the surface is primarily due to the build-up of pressure from the expansion of gases within the magma chamber. As the pressure exceeds the strength of the surrounding rock, the magma forces its way through the crust to reach the surface, resulting in an eruption.
What is the source of heat for Yellowstone's geysers?
The heat for Yellowstone's geysers comes from magma beneath the Earth's surface. This magma heats up the water in underground reservoirs, creating pockets of steam that eventually erupt through geysers.
Is the build up of hardened lava at openings in the Earth's crust from where magma is able to erupt?

What happens inside volcanoes when erupt?
When magma is Heat up at that time magma also gain the kinetic Energy and Explosion occure................

What are the steps a volcano has to go through to erupt?
1. Pressure in the magma chamber begins to build up. 2. The pressure forces the magma to go up through the vent. 3. Then it will erupt

Water !!. . . naah Magma what else ?? !!

When does an active volcano erupt?
An active volcano erupts when there is an accumulation of magma beneath the surface that builds up pressure and eventually forces its way out through the volcano's vent. Factors such as the composition of the magma, tectonic activity, and gas content can influence the frequency and intensity of eruptions.
What is the cause for volcano eruption?
injection of new magma into a chamber that is already filled with magma of similar or different composition. This injection forces some of the magma in the chamber to move up in to the conduit and erupt at the surface.
How do volcanoes aruped?
the magma pushes up and becomes lava. when there is enough pressure lava spews out. that is how a volcano erupt
What causes magma to flow out of a weak spot in the earths crust?
Magma flows out of a weak spot in the Earth's crust due to the build-up of pressure from the molten rock beneath the surface. This pressure can result from the heat and movement of tectonic plates, creating pathways for magma to rise and eventually erupt onto the surface as lava.
