The opening that you are asking about is called a vent. Magma can burst through any weakness in the side of a Volcano or underground passage where Magma is close to the surface. There are also openings called Tubes that are sometimes formed that Magma flows through that are like channels and the Lava stays very hot and flows very fast through them to the end where it comes out very fluid.
This is called the magma chamber.
Before lava reaches the surface it is called magma.
It's called magma when it is under the earth's surface. Once it erupts or becomes visible on the surface, its called lava
Magma in mantal is under great heat and high temperature. Once there is a crack or we called a line of weakness appears on crust's surface,magma would escae to the surface from mantal.Volcanic ashes,gases and magma would throw out and causes volcanic eruptions.

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.
This is called the magma chamber.
