Volcanoes supplied by subduction zones usually erupt due to buildup of pressure of these gases. This lava tends to erupt explosively as solid pieces of ash, cinders, bombs, etc. often filled with gas bubbles. Volcanoes supplied by deep mantle hotspots have almost no gas in their lava and erupt due to buildup of magma rising from the hotspot. This lava tends to erupt quietly as a fluid.
Subduction.

Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
Mount Teide erupted in 1706 due to the buildup of pressure within the volcano. This is the reason that volcanoes erupt in general.
