A volcano erupts because there is mass pressure under it. In a volcano there is hot, melted rock called lava. The hot lava produces gasses that build up underground until there is too much for the rock to contain, that makes the eruption. When there is too much, it bursts the volcano.
There are two types of eruptions. Non explosive and explosive. When they are explosive, it is caused by clouds of hot debris and gases.

What is the usually explosive discharge of steam and volcanic material in a volcano?
The event is called an eruption.
What is the coefficient of discharge?
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.
Which mountain is formed by volcanic material?
A volcanic mountain.
What is volcanic tuft made from?
The correct spelling is volcanic tuff instead of volcanic tuft. Volcanic ash that has been ejected from vents during eruption makes volcanic tuff.
