Strombolian
eruptions cause lava to explode from a vent and then a flow
of lava comes out of the volcano. This happens over and over
again until the volcano is finished erupting. Gases inside the
volcano build up and then release a spray of lava that turns
into a lava flow. The lava flow slows down until the gases build
up again. The lava pieces that are thrown out of the volcano
are bombs that take on a rounded
shape as they fly through the air.
