Liquid magma flows upward through cracks in rock because it is less dense than the surrounding material
The term for the flow of magma through cracks in the Earth's surface is called volcanic eruption. During an eruption, magma is forced through fissures or vents onto the surface, leading to the formation of volcanic features like lava flows, ash clouds, and pyroclastic flows.
That definition could apply to any volcano.
Yes, that is correct. Magma is less dense than the solid rock around it, causing it to rise towards the surface through cracks and fractures in the Earth's crust. This movement occurs due to the buoyancy of the less dense magma compared to the denser surrounding rock.
Any movement of magma inside the Earth is called magma migration. Magma migrates due to differences in pressure, density, and temperature within the Earth's mantle, moving towards the crust through fissures or fractures. This movement can lead to volcanic activity when the magma reaches the surface.
Magma floats to the surface because it is less dense than the surrounding rock. As magma rises, its buoyancy overcomes the pressure of the rock above it, allowing it to flow upward towards the surface. The expansion of gases within the magma also helps to propel it upward.

A lava flow may flow over the surface from a fissure deep enough to reach the magma layer. Or, if under pressure, an eruption from a volcano.

An opening in the Earth's surface through which lava can flow is called a volcano. When pressure builds up beneath the Earth's crust, it can force magma to erupt through a vent in the form of lava, gases, and ash.
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption
The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.

magma flows upward mixed with ash. it cools quickly when thrown up in the air and become pyroclastic blocks bombs and boulders which are the main cause of fatalities
magma is less dense than the surrounding rock, so it is forced upward to the earth's surface
