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 is the name for the volcano when magma breaks through the crust?
When magma breaks through the Earth's crust, it is referred to as a "volcano." Specifically, the term "vent" is used to describe the opening through which the magma, now called lava when it erupts, escapes. The entire geological structure formed as a result of this eruption is also known as a volcanic cone or a volcano.
Does every volcano form in the mantle?
No, the Earth's mantle is to deep and warm for this. Magmas are generated in the upper mantle by a process called partial melting and the melt collects in the crust (in magma chambers at varying depth).
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 can magma form beneath volcanoes?
Magma is hot liquid lava that erupts out of a volcano, it's already under the entire surface of the Earth. In areas where the crust is weak, that's where the magma forms.
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 force that forces magma out of a volcano?
Magma erupts out because of immense pressure inside the earth's crust.

What is lava called before it erupts?
Lava that is still below the earth's crust is called magma.
The movement of magma through the Earth's crust is known as?
The movement of magma through the Earth's crust is known as intrusion.

A volcano erupt when molden rock flows through a central opening which is called?
A volcano erupts when molten rock, known as magma, flows through a central opening in the Earth's crust called a vent. This release of magma, gases, and ash can result in a volcanic eruption.
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
When magma erupts what does it go through?
It goes through, a fault, crack, vent or hole on a volcano.
What are divergent boundaries also called?
They are called constructive boundaries. New crust is constructed as the plates move apart and magma erupts.
