Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
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.
Volcanoes erupt due to the build-up of pressure from molten rock (magma) beneath the Earth's surface. When this pressure becomes too much, it causes the magma to force its way to the surface, resulting in an eruption. Other factors like the composition of the magma and the presence of gases can also influence volcanic eruptions.
Surface tension is a property of the surface of a liquid that causes it to resist external forces, leading to the minimization of its surface area. This results in the surface tending to shrink, rather than expand.
Substance tension refers to the force that holds particles together in a substance. It is responsible for the surface tension of liquids, such as water, which causes them to form droplets and create a "skin" on the surface.

The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
