A volcano is a vent, or opening, in Earthâs surface through which molten rock, gases, and ash erupt. The word also refers to the form or structure, usually conical, produced by accumulations of erupted material.
Types of volcanic materials. Three basic kinds of materials may erupt from a volcano: 1) lava, (2) rock fragments, and (3) gas. The material that erupts depends chiefly on how sticky or fluid a volcano's magma is.he eruption of a volcano. The gas filled magma in the reservoir is under great pressure from the weight of the solid rock around it. This pressure causes the magma to blast or melt a conduit (channel) in a fracture, or weakened part of the rock. The magma moves up through the conduit to the surface.
