Plate Tectonics are related to the formation of volcanoes due to the fact that volcanoes occur during the movement of crust or plates come together. This is when on plate subducts under another which then forces that amount of rock deeper into the earth which begins a melting process. Due to high temperature and pressure the lighter rock that was push under another will melt and become magma which feeds active volcanoes and then builds pressure under the volcano. Once a volcano receives too much pressure the magma can rise out of the volcano and start to flow down the sides or even create an eruption. This flows and eruptions can create larger volcanoes and even create islands. Usually volcanoes are formed on plate boundaries which are in valleys in the ocean ridges and between two continental plates. These are ocean subducts beneath a continental plate or another

Unformatted text preview: ocean plate in which one is pushed under the other. A popular volcano in the United States is Kilauea in the big island of Hawaii. This volcano, which is considered a national park, is the most visited volcanoes among all other volcanoes in the world. This volcano is also said to have the longest uninterrupted eruption in the world because of the unceasing explosions that have been happening sense 1983. The second volcano I am mentioning is because I am a Washington state resident, of course this is Mount Saint Helens. This volcano erupted in 1980 and showed a 5.1 on the Richter scale, which lead to the collapse of the north side of the mountain and resulted in a lot of avalanche debris. This also burnt down around 230 square miles of forest and killing 60 people, this eruption also dramatically changed the landscape surrounding the mountain....
