When cool magma sinks and warm magma rises, yes that is convection.
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.

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.
lava dome
magma rises up out of a volcano by the build up of pressure
