GEOLOGY

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: -A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne.

Detailed explanation-5: -Earth’s crust is made up of tectonic plates that creep in all directions across the planet, traveling as much as a few inches per year. Volcanoes most often form where tectonic plates-thick slabs of crust on the Earth’s surface-meet.
