What is the vent/side vent?
200
Particles produced in volcanic erutpions.
What is pyroclastic material?
200

A volcano that erupts violently if its magma is thick and sticky.

What is an explosive eruption?
200

Sand-sized particles of igneous rock that form when a spray of liquid magma is blown from a volcanic vent by escaping gas.
