How does magma go into a volcano?

Answer 1

Being a less dense liquid, it rises toward the surface, seeking the path of least resistance. The volcano is simply a structure created by the rising magma and the surface features of its lava.

Answer 2

Lava, which is called magma when it is underground, originates from the upper mantle where conditions sometimes allow hot rock to melt. This molten rock rises because it is less dense than its surroundings. It follows underground conduits that eventually lead to volcanoes.

Answer 3

Molten rock, called magma when it is underground, originates in the upper mantle and travels toward the surface through cracks and by melting some of the surrounding rock. In many cases it is stored in a magma chamber a few miles underground before finally following conduits to the surface that lead to volcanoes.

Answer 4

The lava, called magma when it is inside the earth, usually forms in the upper part of earth's mantle where temperatures are in the thousands of degrees. Pressure keeps the rocks here in a solid or semisolid state, but the reduction of pressure or the addition of gasses can trigger melting. This magma then rises up by melting and fracturing the earth's crust, eventually reaching the surface to form volcanoes. Magma is usually stored beneath the volcano in a magma chamber, which is occasionally fed by fresh magma from the mantle. In some cases the magma is no directly from the mantle, but results from crust rocks melted by mantle magma. This tends to generate cooler, more viscous magma, which contains minerals that have lower melting points.

Answer 5

Inside a volcano is molten rock. When there is too much pressure and heat in that volcano, the rock melts and becomes magma, when it reaches the Earths surface it is now lava.

Answer 6

Magma comes out of the mantle through a crack in a plate into a volcano and then it sits in the magma chamber (magma is lava before it comes the volcano)

Answer 7

Magma rises into the magma chamber from the mantle.

Answer 8

The lava from a volcano is the same as that of the lava in the centre of the earth :)

Answer 9

The magma in volcano's is stored in a magma chamber in the earth crust. When the Volcano needs to erupt the lava flows thew the volcano
