Volcanoes
There is a lot to a volcano for good example what makes it erupt, can extinct volcanoes come back to life, how volcanoes form and another(prenominal) things like that. If the magma inside a volcano has enough turn gas and water in it, it will quickly snarf to earths fold up making the volcano erupt. Magma rises because it has a low density. A volcano starts as melted flap (magma) which rises from deep inwardly the earth toward the surface. As the gas filled magma rises it melts gaps in the surround shake and forms a large chamber. Pressure from the solid rock around it forms a large chamber. Pressure from the solid rock around it forces the magma up to the surface through the conduit in the weekend part of the rock. The gas and melted rock blast let bug out an opening called the central vent. Another question you tycoon get under ones skin is, can extinct volcanoes become active and the answer is yes. near because a volcano does not erupt doesnt specify it is not active. Volcanoes ar considered extinct when all seismic application has stopped. Deep inside the earth between the molten iron out core and the thin crust at the surface, there is a solid body of rock called the mantel.
When the rock from the mantel melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Also a question you might have is how do volcanoes form. Volcanoes are formed unremarkably near plate boundaries, most commonly convergent/ cataclysmic plate boundaries, such as the Pacific Ring of Fire, which contains closely 68% of Earths volcanoes. A volcano is formed when there are cracks in the plates. When a denser plate, such as the oceanic plate, numbfish ducts under another plate, either a continental or oceanic plate, the plate will melt under organic temperatures in the mantle. This will form cracks in the plates, which results in magma menstruum out from the mantle through the cracks in the plate and out of earths surface. The magma will then harden and...If you want to get a full essay, order it on our website: Orderessay
