Where does a volcano get its lava from?

Answer 1

Lava gets its heat from deep within the Earth. When the Earth was forming, it was molten and it still has not cooled down completely. The mantle, which is beneath the Earth's crust, is where magma, or lava as it is called when above the Earth's surface, is held. Ruptures in the crust will cause lava to escape from the mantle.

Answer 2

The Mantle, but ultimately from radioactive decay.

(This question occupied geologists for a long time until the discovery of radioactivity and its properties, for earlier estimates of the Earth's age based on ordinary thermodynamics failed as more was learnt of the age of rocks andgeological processes.)

Answer 3

lava makes there own lava since some volcanos are in the ocean its closest to the middle of the earth and the middle of the earth is really hot so it melts the rocks to make LAVA !!!!!!!!!!!!!

Answer 4

Volcanoes get their heat from inside the earth. Some of this is heat left over from earth's formation, and some, some comes from radioactive decay and from the crystallization of minerals, and some is believed to come from nuclear fission at earth's core.

Answer 5

The lava, called magma when it is underground, is usually stored in a magma chamber beneath the volcano. The magma chamber is occasionally refilled by new magma which formed by melting rock in the upper mantle.

Answer 6

The lava originates from Earth's mantle, which is extremely hot due to a combination of residual heat from Earth's formation and heat from radioactive decay.
