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 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.


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.


Do these hot spot volanoes tend to erupt more explosively than other volcanoes?

no they do not erupt more explosively. It depends on its gas and on its viscosity. an example is Kilauea in Hawaii it does not erupt explosively.

What is a vent called through which gas and ash and magma erupt onto the earth's surface?

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.


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.


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.
