Much of the gas that comes out of a volcano was originally trapped in the magma under pressure. When the magma encounters lower pressure the gas comes out. The process is similar to soda fizzing when the bottle is opened. some of the gas may be steam the formed from groundwater boiling from the intense heat.
The gas was trapped in the magma.
gas gets trapped doesn't it and magma or lava gets shot out
yes.
yes
A volcano " vents " gas when pressure builds up
Wear gas masks, stay inside, and be prepared to evacuate if neccicary.
Gas is stored in the Magma chamber at the bottom of the volcano, along with the magma.
A volcano may release smoke, or volcanic gas, both before and after it erupts. This gas can be a sign of increased activity within the volcano and may indicate that an eruption is imminent. It is important to monitor changes in gas emissions along with other volcanic activity to predict eruptions accurately.
It trickles slowly down the volcano and then turns into solid and becomes part of the volcano. That's why volcanos are so HUGE!!
A volcano is made of solid rock.
a mountain
Smoke and sulfuric gas
