Magma

my paper I will be giving information on how often do volcanoes erupt. First,I will explain how magma can trigger volcanic eruption. Next, I will discuss how buoyancy can also trigger a volcanic eruption. Finally, I will predict how pressure from gases in the magma and magma chamber can cause a volcanic eruption,and give some more details about my volcano. It depends on the volcano to erupt oftenly. Some volcanoes erupt very often (and some like Kilauea almost never stop). On the other hand, some volcanoes are inactive for very long periods of time between eruptions.There are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma chamber,Bodies of magma rise in the crust until they reach a point of neutral buoyancy. The expansion of gases brings the magma closer to the surface and…

WARNING! There has been word that the Yellowstone supervolcano is about to blow. A supervolcano is like a regular volcano but the eruption is thousands of time greater than a regular explosion. The last time this volcano erupted was about 174,000 years ago. Yellowstone is still active and another eruption is possible but very unlikely. If it does happen to erupt it could end civilization. There is huge volcano under Yellowstone National Park, which is being watched 24/7. If or when this…

comes up is death and destruction. However, volcanoes can help living things, and they can build as well. No matter where you live, volcanoes effect you. The question is, how? Volcanoes can cause death and destruction, and some large damage to surrounding areas. Take Pompeii for example. Everyone has probably heard of Pompeii once. In case you haven’t, Pompeii was a city built near Mt. Vesuvius in Italy. One day, the volcano erupted, and the city was covered in ash. There were many…

The second most abundant element in the Earth’s crust other than oxygen is silicon which if by mass is around 25.7g or 23%. However in nature, silicon never exist as a free or pure element but instead it mostly combines with the most abundant element in the Earth’s crust, oxygen, hence producing silica (SiO₂) or silicate minerals. The most prominent charge of Si in the crust is +4 rather than +2 which involve a silicon atom to bond in a tetrahedral manner with 4 other oxygen atoms giving rise to…

facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic activity, the first underwater volcano observatory is located near the volcano. (www.pmel.noaa.gov) According to www.en.wikipedia.org, the two plates that create the boundary are called the Juan de Fuca plate and…

Steam and rumblings are some of the signs it's giving off that sooner than later it is going to erupt. It has been struck by a total of 253 earthquakes. Volcanologist believe that an eruption is gonna happen anytime soon. People were being evacuated because of signs of the volcano was giving off. Mount Agung reached its highest point which led to that believe. If this volcano were to erupt again it would be horrible. Mount Agung is located in the Indo-Australian Plate. It is part of the ring of…

A volcano is a surface landform resulting from the extrusion of magma from underground as lava, ash, rocks, and gasses are erupted in various proportions. Each year, around 60 major volcanoes erupt globally. How hazardous each one is dependent on a variety of human and physical factors that determine the level of impact on human activity that each event exerts. I will be looking at how the physical properties of a volcano, interact with human variables to make certain volcanoes more hazardous…

Shield volcanoes are formed by many different lava flows that layer over time. Mount Kilauea is a well-known shield volcano in Hawaii. Before it erupts, it is known to inflate as magma pushes upward from its magma chamber. Seismic activity usually precludes Kilauea’s eruptions by about 24 hours. Their eruptions consist mostly of lava flowing out of the summit or through lava tubes in what is known as a flank eruption. The lava that flows from these volcanoes is highly basaltic in nature. Because…

discovered in 1977 near the Galapagos Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents that were pouring out hot fluids from beneath the ocean floor (Hydrothermal Vents). Hydrothermal vents are fissures in the earth’s surface from which geothermally heated water rises. They are normally found near volcanically active areas,…

Volcanoes: Destruction Makers Natural disasters are tragic events caused by nature that have a negative impact on man. Volcanoes can be considered one of the worst types of natural disasters because they often kill people, injure people, and/or destroy property. One example of a volcano is Mount Saint Helens. “A volcano is an opening in Earth’s crust through which ash, gases, and molten rock from below ground erupt onto Earth’s surface or into the atmosphere” (Kobasa). Volcanic eruptions…
