Volcanoes. They are all over the earth, both on land, and under the sea. Volcanoes are not exclusive to Earth though, as they can be found on other planets. What is a volcano? A volcano is a spot in the crust where molten magma can escape through the surface causing an eruption, spitting out lava, ash, and various gasses into the atmosphere. Volcanoes can be blamed for both creation and destruction. When erupting, a volcano typically releases molten lava, ash, and gasses unto the surface, and into the atmosphere. They can most often be found where tectonic plates push or pull towards or away from each other, respectively. Where tectonic plates move past each other there is much less volcanic activity. If a volcano is found in the middle of a tectonic plate rather than the edges it is called intraplate volcanism. Intraplate volcanism is caused by hotspots, places in the middle of tectonic plates where molten magma pools in chambers miles under the surface that can be miles both wide and high. When a volcanic eruption occurs lava is the first thing people think of that is emitted. This one of many materials that come out. The typical volcano people think of is a mountainous land mass that spits lava from a crater in the middle of it. This is indeed a volcano, but only one of a few types of volcanoes. These types include shield volcanoes, lava domes, cryptodomes, cinder cones, stratovolcanoes, supervolcanoes, submarine volcanoes, and subglacial volcanoes. Of those types, the major volcano types are shield volcanoes, stratovolcanoes and cinder cones. Active volcanoes are either volcanoes that erupt frequently, or usually have volcanic activity ranging from earthquakes or tremors to gas emissions. Eruptions can last from a few days to a few months. If a volcano has erupted even as far back as historic times a volcano may be called active. Volcanoes are not all necessarily dangerous, some are even dormant or extinct. A dormant volcano is one that is no longer active....
