Volcanoes

media type="custom" key="22027350" ==Volcanoes are produced when molten rock (Magma) rises through the Crust to the surface. These locations can be along the edges of the Plates that make up the Crust or a hole through the Plates called "hot spots". The Hawaiian Islands are volcanoes formed by a "hot spot" in the center of the Pacific Plate. Upon reaching the surface, the molten rock is called Lava.==

**The Molten rock material forms 3 types of volcanoes depending on how the Lava cools and the layers of the materials that form.** media type="youtube" key="4F9ovQf9-dg" width="560" height="315"

 * = ==[[image:Strato_Volcano.jpg]]== ||= ==Stratovolcanoes form from the buildup of lava and ash layers. These volcanoes tend to erupt when the opening becomes "capped" by cooled lava. The pressure builds up inside the volcano until the "cap" is blown off the volcano as a violent eruption.== ||
 * = ==[[image:Shield_Volcano.jpg]]== ||= ==Shield volcanoes are among the largest of volcanoes. They form from layers of lava that flow freely and then harden. The Hawaiian Islands are Shield volcanoes that have formed from a "hot spot" in the Pacific plate of the Crust. As the Pacific plate moves slowly over the "hot spot", lava is released. As time goes by, new Hawaiian Island will form. Mauna Loa is the largest volcano on Earth and is found in Hawaii.== ||
