Plug or a Neck or both? in Many geologists use the terms “neck” and “plug” terchangeably, while others believe the terms apply to while others believe the terms apply terchangeably, types of volcanic structures. Some geologists different definitions of lava and magma to make use the different a volcanic the distinction between a volcanic “neck” and rock beneath “plug.” Magma is molten or partially molten surface. Magma collects inside a volcano’s the earth’s breaches magma chapter before it erupts. When magma surface, the magma becomes lava and a the earth’s volcano is formed. Geologists who make the distinction between volcanic necks and plugs consider a volcanic “neck” indicative of an actual volcano – a column of igneous rock formed by congelation of lava in the conduit or vent of a volcano and later exposed by the erosion of surrounding rocks. In contrast, these geologists consider a volcanic “plug” to be a structure formed by a body of magma that never the softer exterior surface. Over time, reached the earth’s leaving behind the now-cooled rocks eroded away, a “plug” is an intrusive body formed magma. Put simply, by magma which cooled underground and was later exposed by erosion.
