What is the definition of dome volcano?
a lava dome is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano.
a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.
I don't know about viscous, but a lava dome is a steep-sided dome of thick lava extruding from a volcanic vent. a viscous lava dome is when the lava from the volcano contains alot of silica. Viscous=sticky. So the lava cools quickly of the sides of the volcano. And often a viscous lava dome volcano is explosive.
A lava dome volcano is also referred to as dome volcano. It forms when lava blocks the vent. The lava cools, then breaks apart, new lava covers the cooled lava (molten rock) which makes a dome shape. The lava involved in these domes is extremely viscous, and so does not readily flow away from the source.
lava dome has a more vicious lava than of a shield volcano.lava dome is formed by relatively, small bulbous gases,however for the shield volcano it is made up of BASIC lava.the basic lava spreads over a wide area before it solidifies for lava dome it is too vicious to flow any great distance. shield volcano produces a gently sloping cone.an example of a shield volcano is the mauna loa in Hawaii where as an example…
