A volcano is a mount (or mountain) that has magma in it. A volcano also is like an earthquake releasing pressure from the inner core of the earth. If there is a lot of pressure to be released this will cause the eruption to be bigger and more destructive, like the volcano Mount Tambora that erupted in 1815.
a volcano is formed by tectonic boundaries. when the magma in Earth's interior gets hotter, it rises out of a volcano which is like an opening. the magma goes out of the volcano.
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.
