GEOLOGY

Detailed explanation-1: -Magma. A volcano has a pocket of magma below the surface, called a magma chamber. A long tube, called a pipe, connects the magma chamber to the surface. At the top of a pipe is an opening called a vent (most volcanoes have one primary vent, and one or more secondary vents).

Detailed explanation-2: -The location beneath the vent of a volcano where molten rock (magma) is stored prior to eruption. Also known as a magma storage zone or magma reservoir.

Detailed explanation-3: -The central conduit by which magma rises through a volcano is termed a volcanic pipe. A volcanic pipe may be anywhere from a few yards to about 0.5 mi (0.8 km) in width.

Detailed explanation-4: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. When magma flows onto Earth’s surface, it is called lava.
