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.

When magma rises and bulges the crust?
Dikes and sills may form when magma rises and bulges Earth's crust.
Why does magma rise when it is nearer to the core?
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.
Is cool magma sinking and warm magma convection?

How does the magma rise from the volcano?
magma rises up out of a volcano by the build up of pressure

How is a magma chamber formed in a volcano?
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.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
