GEOLOGY

Detailed explanation-1: -All volcanoes contain a central vent underlying the summit crater of the volcano. The volcano’s cone-shaped structure, or edifice, is built by the more-or-less symmetrical accumulation of lava and/or pyroclastic material around this central vent system.

Detailed explanation-2: -A side vent is an opening in the side of a volcano through which volcanic materials ( lava and gases) erupt.

Detailed explanation-3: -Throat: The uppermost section of the main vent is known as the volcano’s throat. As the entrance to the volcano, it is from here that lava and volcanic ash are ejected.

Detailed explanation-4: -Hawaii has volcanoes with many side vents that have built the islands with very wide bases. Some volcanoes on the other hand have few or no side vents. The materials that makes up the magma (gases, minerals, steam) determines how the magma will arrive at the surface.
