The explosiveness of a volcano is determined by two factors. The obstacles in the magma's path and the type of volcano. When there is chunks of rock and hardened magma in the vent the liquid magma builds up until it sprays out at hufe ferocity. If there is little or no debris then the magma simply spews out. As for the type of volcano when the tectonic plates move apart it forms a row of GENTLE volcanoes but when they crash together the volcanoes are much more explosive.

What determines the types of volcanic eruption?
The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.
