lava dome
magma
It makes a volcano because as it rises it pushes up the sea floor and it rises.
Magma rises when it is being pushed or heated from below.
Mama rises when it is less dense than the rock surrounding it, and when the area around it allows free movement. The pressure allows the magma to convert form a liquid to a gas, which causes it to rise.
Dikes and sills may form when magma rises and bulges Earth's crust.
Water that is heated expands and rises to the surface of the tray. Similarly, the magma expands and rises to the surface of the tray. Similarly, the magma nearer the core expands and rises to top of the mantle.
When cool magma sinks and warm magma rises, yes that is convection.

magma rises up out of a volcano by the build up of pressure
When magma is being heated it rises. When it is cooled, it sinks.
term that is used to describe when magma rises to earth's surface but does not occur at a boundary
Magma rises through fractures from beneath the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. As more magma rises up below it, the pressure in the chamber grows.
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
