Volcanoes are evidence of the ceaseless tectonic activity that our planet has. The molten core of the earth drives all of the processes we see, including volcanoes, earthquakes, even as high up as the northern lights. The heat that is inside of our planet is the driving force behind volcanoes, however volcanoes form in many different areas, and under many different conditions. Different types of volcanoes are evidence of different processes being present underground. However, to put it simply without the heat from the core of the earth there wouldn't be any volcanoes.
A geyser is an underground volcano with water on the surface of it. This water is then boiled by the magma.
Anywhere that volcanoes, hot springs, or even hot rocks underground can be accessed.
