Well, water is really what a tsunami is. An earthquake triggers that and so as a volcano. That's the similarities.
Or, some volcanoes can be in water.
I'm just guessing. Maybe the second one won't count.
because
A geyser is an underground volcano with water on the surface of it. This water is then boiled by the magma.
because volcanoes can also be caused by plates
they are not
No. Mercury is a geologically dead planet. It has no volcanoes, not atmosphere, and no water.
A volcano is not like a forest fire. Oceans have no affect on volcanoes. The heat within the Earth that drives volcanoes is too great to be extinguished by surface water. See related link for video.
Volcanoes are not biological therefore do not 'live' anywhere.
Pressure. Do a Google search on the relation between volcanoes and pressure, or even your question.
how are volcanoes and the process of plate tectonics related
badly
yes
