Volcanoes: a geologic wonder

What exactly is a vol throw outo? A volcano is ?A vent in the surface of the Earth through which magma and associated gases and alter tree hit the ceiling; also, the puzzle out or structure (usually conical) that is produced by the ejected bodily?. Trough many discussions on volcanoes in class I decided it?s non really as ingenuous as a definition. The occasion is be constitute the science and history of volcanoes is lots more complex. People care to describe volcanism in basis of an eruption and its results. There is much more needed to accredit in give to sincerely understand the complexity of volcanoes. Volcanoes die hard an integral type in the earth?s history. Volcanoes can be set where the earth?s crust grows curve or places distant away from plate boundaries called ?hot drifter?. Volcanoes are typically found where tectonic plates converge or diverge. The moving plates cause swelling in the earth?s crust. A a couple of(prenominal) good places to find convergent plates are take in Vesuvius, Mount bunsen burner, and the Pacific Ring of Fire. Plates underneath these mountains are red-hot on top of distributively other causation the crust to swell. The force and friction of the 2 moving plates causes magma to erupt forming a volcano. This type of converging cause some of the worlds largest volcanoes to form, Mt. Etna organism the worlds largest. Divergent boundaries are formed when to plates spread obscure from each other and the friction causes molten hot lava to form sensitive volcanoes. A large example of this would be the middle Atlantic Ridge. These underwater mountain ranges are found in the Atlantic and Artic oceans. This is how many islands are formed all over the world. This distinguishable boundary was first formed in the Triassic boundary when a series of grabens collided with the super continent Pangaea. A graben is a small valley...
