GEOLOGY

Detailed explanation-1: -All volcanoes have a pocket of magma beneath the surface. Beneath a volcano, magma collects in a magma chamber. During a eruption, the magma forces its way through one or more cracks in Earths crust .

Detailed explanation-2: -All volcanoes have a pocket of magma beneath the surface and one or more cracks through which the magma forces its way. Beneath a volcano, magma collects in a pocket called a magma chamber.

Detailed explanation-3: -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-4: -All volcanoes are connected to a reservoir of molten rock, called a magma chamber, below the surface of the Earth.

Detailed explanation-5: -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.
