Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Dissolved gases trapped in the magma provides the force that causes magma to erupt to the surface. Magma is molten material before it reaches the surface and is lava.

Pressure.
The primary explosive force that results in an eruption is the release of built-up pressure in the Earth's mantle. This pressure is caused by the accumulation of magma beneath the surface, which contains volatile gases such as water vapor and carbon dioxide. When the pressure becomes too great, it causes the magma to explosively erupt to the surface, resulting in a volcanic eruption.
by the earths plates moving and causes force to the volcanoe and it starts erupting.
The force that causes turgor pressure is osmosis.
A force that resists motion of one surface across another surface is called FRICTION(or FRICTIONAL FORCE)
