Lava is magma that reaches the surface. Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
What else can I help you with?
The path that magma travels along is called a what?
The path that magma travels along is called a conduit. This conduit allows magma to move from its source deep within the Earth to the surface where it can erupt as volcanic material.
Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.
Into which layer of the earth does the magma chamber extend to?
Magma is generated within Earth's mantle, the thick layer between Earth's crust and outer core. Rock found deep within the crust is extremely hot, soft, and pliable, but rock does not become liquid until much deeper in the upper mantle. Pockets, or chambers of magma, can originate at various depths within the earth. The composition of the magma varies and indicates the source materials and depth from which they originated. Silicondioxide (SiO2) is the predominant ingredient.
What are magma and sediment and how are each formed?
Magma is formed by the heating and cooling of the Earth's crust. Sediment is formed by the soil that is moved downstream from the source of a river to the mouth of the river and the resulting delta.
What is the source of magma for intraplate volcanism?
Rift zone
The liquid part of the earth is called the what?
MAGMA
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
Mantle is part of the Earth's lithosphere.
What is a soft rock that is heated almost to its boiling point?
the answer is magma cause magma is soft nearly molten rock.
What is a cavern beneath Earth's crust that is the source of heat for all Yellowstone thermal features?
A magma chamber.
Which layer of earth is the source of molten rock called magma that sometimes rises to earths surface?
the mantle
The path that magma travels along is called a what?
The path that magma travels along is called a conduit. This conduit allows magma to move from its source deep within the Earth to the surface where it can erupt as volcanic material.
What is pressure and heat that produce magma are caused in part by?
Pressure and heat that produce magma are caused in part by the movement of tectonic plates deep within the Earth's mantle. This movement leads to the melting of rock at high temperatures and pressures, resulting in the formation of magma beneath the Earth's surface.
Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.

Why lava and magma is together?
Magma is just lava inside the earth, and lava is just magma outside the earth.
Hot melted rock inside the earth is called?
The molten rock inside the Earth is called magma. When magma reaches the surface, it is called lava.
