The molten material that a volcano vents is called magma when it is still underground and lava when it reaches the surface. Magma is generated by the partial melting of rocks in the Earth's mantle, and its composition can vary depending on the type of volcano. When a volcano erupts, it releases lava, gases, and ash onto the Earth's surface.

What is it called that connects pool of magma to the crater?
Magma usually refers to molten rock when it is still underground, and a crater is a cup shaped depression in the surface whether in a volcano or not. If a crater were full of molten rock we'd call it lava. It might be fed by a magma pool below the surface.
What is the focus point of a VOLCANO?
The focus point of a volcano is the opening or vent at the Earth's surface through which molten rock, ash, and gases are erupted during an eruption. It is where the volcanic activity is concentrated and where materials are expelled from the volcano.
What is newly formed hot forced upward that forms volcanic mountains?
Magma is newly formed hot molten rock that is forced upward from Earth's mantle through a vent or fissure in the crust. When this molten material reaches the surface, it solidifies and accumulates over time to form volcanic mountains.
What is the definition of volcano?
A volcano is a mountain that opens downward to a pool of molten rock below the Earth's surface. When pressure builds up, eruptions occur, sending lava, rock, ash, and gases into the air.
What are the top definitions of the word volcano?
A vent in the Earth's crust where magma, gas, and ash are expelled. A mountain formed by the accumulation of volcanic materials around a vent. A geological feature often associated with explosive eruptions and lava flows.
What is a molten material that leaves a volcanoes vent is called?
it's called lava! lava is what's on the surface of a volcano, and magma is what's underneath
What is the opening through which molten rock flows out to the surface called?
The opening through which molten rock flows out to the surface is called a volcano vent or volcanic vent. It is a rupture on the Earth's surface that allows magma, gases, and ash to escape during a volcanic eruption.
What is a molten material that leaves a volcanoes vent called?
it's called lava! lava is what's on the surface of a volcano, and magma is what's underneath
Is the molten rock from the mantle that rises up the vent and flows out of a volcano?
yes. :)
Is vent a volcanoes name?
No. A vent is the part of the volcano from which material erupts. One volcano can have multiple vents.
What does molten rock and gas leave the volcano through?
Molten rock and gas leave the volcano through an opening in the Earth's crust called a vent. The molten rock, known as magma when underground and lava when at the surface, flows out of the vent during an eruption. Gases such as water vapor, carbon dioxide, and sulfur dioxide are also released into the atmosphere during volcanic activity.
How does volcano differ from magma chamber?
A volcano is a vent or hole in the ground where molten rock and associated gasses erupt. A magma chamber is a chamber underground, often under a volcano, where molten rock is stored.
What is the material which is forced out of volcano vent called?
The general term for the different types of material that a volcano spews out is ejecta.
Is a vent at the top of a volcano?
If the volcano is active, there may be vents around the volcano as well as on top. A vent is where volcanic material (lava, steam, ash) is being released.
What you mean by volcanos?
A volcano is a vent (opening) in the earths crust through which molten materials erupts suddenly.
When a volcano erupts does the molten material create magma plateaus?
yes
What is the rock material called that has filled in the vent of a volcano and hardened?
Basalt
