When a volcano erupts hot matter is ejected through the what?

When a volcano erupts, hot matter is ejected through the vent, which is the opening in the Earth's crust through which magma and volcanic gases are expelled.


What you mean by volcanos?

A volcano is a vent (opening) in the earths crust through which molten materials erupts suddenly.


What force that forces magma out of a volcano?

Magma erupts out because of immense pressure inside the earth's crust.


How does the center of the earth cause a natural disaster?

The mantle is made of lava. When lava makes cracks in the crust it makes a volcano. When the volcano erupts it makes a natrual diaster.


A vent or hole in the surface of the earth when this erupts it may release gasses from inside the earth?

You are describing a volcano. When a volcano erupts, it releases gases, ash, and lava from deep within the Earth's crust through vents or openings in the surface. This process can result in various volcanic hazards and eruptions can be explosive or effusive depending on the type of volcano.


What happens when layers of eath crust crack and move?

An Earthquake


Where does the magma get trapped in the layers of the volcano where the magma never reaches outside?

if you mean after it erupts then the magma should be sticking to the sides of the volcano on the inside but it may soon melt because of the scorching heat but if you mean when it doesn't erupt then i don't know


Is kilauea volcano a hot spot?

Yes, Kilauea volcano in Hawaii is considered a hot spot volcano. This means it is formed by a mantle plume beneath the Earth's crust, creating a source of heat and molten rock that erupts to the surface.


What happens when a plate of oceanic crust collides with a plate of Continetal crust why?

the oceanic crust slides down and burns in the mantle and forms a volcano


Do volacnoes erupt as often as earthquakes happen?

no because earthquakes are from mountains split into two sides and the volcano erupts when the crust cant hold the heat from the core


Does the magma and lava from a volcano come from the mantle?

Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.


How does a volcano erupt and what causes it to erupt?

When a destructive boundary of two tectonic plates occurs the oceanic crust sinks underneath the continental crust as it is more dense, the oceanic crust then melts in the subduction zone and becomes magma in the mantle, this increases the pressure in the mantle and causes the magma to shoot up the volcano shaft and burst out of the top, this is an eruption
