Detailed explanation-1: -A volcano is an opening in the Earth’s crust that allows molten rock, gases, and debris to escape to the surface. A volcanic eruption may release acid, gases, rocks, and ash into the air. Lava and debris can flow at up to 100 miles per hour, destroying everything in their path.

Detailed explanation-2: -A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt.

Detailed explanation-3: -Vent-The opening or place at Earth’s surface through which magma, rock fragments, and/or volcanic gases are emitted. Volcanic edifice-A mountain or cone that is the main portion of a volcano.

Detailed explanation-4: -Answer and Explanation: An opening in the Earth’s crust is called a vent. A vent is where magma can come above the surface as lava. A vent can also be the source of gas or ash.

Detailed explanation-5: -A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. This molten rock is called magma when it is beneath the surface and lava when it erupts, or flows out, from a volcano. Along with lava, volcanoes also release gases, ash, and solid rock.
