The magma forms sills and magma chambers.
geothermal
Magma is less dense than rock and is buoyant due to this density difference. It will seek out any weaknesses in the rock above it to reach the surface.
magma chambers
Yes. That is what the asthenosphere is.

magma
the magma in the core of the erath pushes it's self through a crack in the erath's crust and when the magma burst out from the pressure behind it, it becomes lava, so magma is in a volcanoe.
They are made of magma (melted rock) under the water are volcanoes which burst and let magma get out the magma travels up and lays on the water which then drys and turns into an island.
