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.

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.


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.
