volcano
volcano A naturally occurring vent or fissure at the
Earth's surface through which erupt molten, solid, and gaseous materials. The
viscosity, gas content, and rate of extrusion of the
magma probably determine the shape of the mountain built by the
eruptions. The
magma may reach the surface either through a single channel (see
CENTRAL VENT VOLCANO), or through a series of vertical fractures (see
FISSURE VOLCANO). Types of eruptions are named after volcanoes associated with them. See
HAWAIIAN ERUPTION;
PELÉEAN ERUPTION;
PLINIAN ERUPTION;
STROMBOLIAN ERUPTION;
SURTSEYAN ERUPTION;
VESUVIAN ERUPTION; and
VULCANIAN ERUPTION.
