Gasses do not necessarily cause a volcanic eruption, but they often countribute. Water vapor is generally the most significant gas, but others such as cabon dioxide and sulfur dioxide are also present.

What shoots out of a volcano during an eruption?
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
How did the wolf volcano erupt?
The lava flowed down the volcano and gas got in the side vents
How does the release of trapped gases in magma cause a volcano to erupt?
Some of the trapped gas in a magma will be water vapour, but at very high temperature. As the magma rises in the volcanic pipe, the pressure will lower, and the entrained vapour will expand rapidly = an explosion.
What is a vent called through which gas and ash and magma erupt onto the earth's surface?
This is known as a volcano.
Does a composite volcano have a high gas content?
Yes. Composite volcanoes often have a high gas content in their magma, which is why they often erupt explosively.

How many times will a volcano erupt on Jupiter?
No volcanoes will erupt on Jupiter because it is a gas planet. As far as science knows there is no solid ground within the gas of Jupiter, therefore no volcanoes can exist.

Yes. Composite volcanoes often have a high gas content in their magma, which is why they often erupt explosively.
Is volcano and volcanic the same thing?
No. Volcano is a noun describing a mountain or hole in the ground through which lava, ash, and gas can erupt. Volcanic is an adjective that means "of, relating to, or produced by a volcano or volcanoes."
How can you predict WHERE a volcano is going to erupt.?
A volcano will is generally a prominent feature that stays in one place. Monitoring seismic activity, gas emissions, and shifts in the surface on and near a volcano can be used to determine if an eruption is likely.
Why are volcanoes that erupt infrequently more destructive then volcanoes that erupt continuously?
Volcanoes erupt infrequently more destructive and active than volcanoes that erupt continuously because the volcano that didn't erupt in a while had more pressure than the volcano that erupts constantly. When more pressure builds up, gas wants to get out as soon as possible. When it does, the magma comes out, it pushes and pushes out since all thee pressure builded up.
What caused the eruption of the Arenal volcano in Costa Rica on June 29th 1968?
All volcanoes erupt for the same reason: magma making its way to the surface of the water inside the volcano, where it turns into steam and gas. The steam and gas propels the magma from the volcano, causing the eruption.
Can you tell that a volcano is about to explode by looking at it?
Not just by looking at it. Scientists do detailed analysis using seismographs, and chemical samples of gas and,where possible, lava. These can point to whether or not a volcano is getting read to erupt.
Would a volcano flow lava then explode?
Not usually. It is more common for a volcano to erupt explosively and later extrude gas-depleted lava. That being said, lava domes can sometimes explode.
