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.

∙ 12y agoMagma comes from the melting of mantle due to the presence of high temperature at greater depth. This means that the magma comes from the center of the earth.

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.
Magma that has emerged from the earth?
Magma that has emerged from the earth is basically lava.....
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.
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
What is the molten rock found beneath the surface of the earth?
Molten rock beneath the earth's surface is called magma.
The liquid part of the earth is called the what?
MAGMA
What is a soft rock that is heated almost to its boiling point?
the answer is magma cause magma is soft nearly molten rock.
Which layer of earth is the source of molten rock called magma that sometimes rises to earths surface?
the mantle
What is a cavern beneath Earth's crust that is the source of heat for all Yellowstone thermal features?
A magma chamber.
Does the weather cause a volcano to erupt?

Why lava and magma is together?
Magma is just lava inside the earth, and lava is just magma outside the earth.
What is magma and what does it do?
Magma is lava underneath the earth. The tectonic plates of the earth float on it.
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.
How does magma change the earth surface?
When magma erupts on to the earth's surface it hardens and forms new land.It depends on if your talking about magma or lava, lava is on the surface of the Earth and magma is inside (underground).
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
