A volcano erupts, and lava spews everywhere, burning every living thing it touches. By the time the eruption is over, not a single blade of grass is still living in the area. Volcanoes and their magma have always been viewed as chaotic, uncontrollable objects. But what if humans could use them for their own advantage? Geothermal energy is energy from Earth’s heat. Geothermal energy has some advantages over other types of energy. One is that it is available over 90% of the time compared to coal plants

and the hot magma beneath the caldera can cause an eruption which will cover Las Alamos, and many small towns in the region Brandon Neel 4/9/2014 English 218 History One of the largest and youngest volcanoes and considered a super volcano in the United States is known as the Valles Caldera. The location of the volcano is in the Jemez Mountains by Santa Fe New Mexico. New research from the scientists in the Valles Caldera concerning ejected microscopic textured rock and hot magma beneath the

on the earth’s crust. The rupture leads to a pool of molten magma, near the core of the earth. When the earth’s crust ruptures, pressure builds up, resulting in an eruption occurring to release the pressure. Toxic gases and rocks shoot up through the opening, overflowing the air with hot lava fragments. This can bring floods, avalanches, and can even provoke tsunami and earthquakes. How are they formed? Volcanoes are created when magma from within the Earth's crust rises to the surface. At the

Mount St. Helens, Mount Rainer, and Crater Lake. Volcanoes have three common features such as craters, caldera, and geysers and hot springs. A caldera is a huge depression that is formed after the eruption from the collapse of a partially emptied magma chamber. In the last million years, ten major caldera formed after eruptions, which included Crater Lake in Oregon. Mount Mazama, also known as Crater Lake, was a large composite volcano that was constructed by the episodic growth of many overlapping

plate and the Juan de Fuca tectonic plate. The plate boundary is a divergent plate boundary, meaning that the two plates are slowly pulling away from each other. This causes a gap to be left behind in the ocean’s crust. Magma from deep below races to fill in the gap. Once the magma reaches the ocean water, it is cooled into a solid

oceanic plate and a continental plate. When the denser oceanic plate subducts beneath the less dense continental plate, solid mantle material melts at the subduction zone. This forms magma that is kept in a magma chamber. Pressure in the magma chamber builds up over time and when this pressure is released, the magma rises through the earth’s crust to cause volcanic eruptions. The lava from the eruption cools to form new crust and the layers of ash and lava form the volcano. Aerial Volcano is an

Volcanoes have been around for many centuries and will continue to exist for many more to come. Many people have their ideas of what they believe volcanoes are. Most believe that it is basically a mountain that shoots out lava, destroying anything and everything nearby. This assumption is actually proven accurate. Volcanoes are considered one of the most dangerous natural disasters; they can erupt suddenly, destroying everything in its way. People tend to be so afraid of volcanoes that most of them

● The Yellowstone Supervolcano The first part of this memo is going to discuss the Yellowstone supervolcano. For years people have traveled regularly to Yellowstone to enjoy the beauty of its 300 geysers and thousands of mud pots and steam vents that bubble and boil at the service. These tourist are completely oblivious to the massive supervolcano deep underneath the surface of Yellowstone. For decades scientists specializing in the world of geophysics have studied the Yellowstone volcano. It

Sometimes this magma slowly works it’s way towards the upper surface of earth. Internal pressure builds up and results into a volcanic eruption. As the volcano erupts, ash and lava get deposited everywhere. The lava cools slowly being a poor conductor of heat. The lava

extremely high temperatures, it melts ( magma) , and builds up alongs with other gases and rocks. The magma then rises up the volcano, until it reaches the volcanic vent, where it erupts. Once magma reaches the surface of the volcano, it becomes lava where it flows down the volcano. Volcanoes usually occur near or in the middle of major tectonic plate boundaries
