When magma reaches the top of the asthenosphere it can start to work its way through the lithosphere, potentially reaching the surface to erupt from volcanoes.
When the subducting plate reaches about 100 kilometers (60 miles) into the Earth's hot mantle, it triggers partial melting of the overlying plate and forms new magma. Some of the magma rises and erupts as volcanoes.
Molten rock (magma) that spews from a volcano is called lava, When it cools, the lava forms igneous rocks.
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
Molten rock under the surface is called "magma". When magma reaches the surface it is called "lava".
Hot liquid rock is called magma when it is beneath the Earth's surface and lava when it reaches the surface through a volcano.

contains hot molten rocks or magma
The molten rock inside the Earth is called magma. When magma reaches the surface, it is called lava.
All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.

The Lowwer Mantle, reffered to as Asthenosphere.

Hot liquid rock is called magma when it is beneath the Earth's surface and lava when it reaches the surface through a volcano.
Hot liquid rock is called magma when it is beneath the Earth's surface. Once it erupts and reaches the surface, it is referred to as lava. Both magma and lava are composed of molten rock, minerals, and gases.
Magma is the hot molten rock found in underground chambers, which forms when rocks melt at high temperatures and pressures beneath the Earth's surface. When magma reaches the surface, it is called lava.
