  • How Often Do Volcanoes Erupt

    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…

  • Hydrothermal Vents Research Paper

    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,…

  • Earth's Crust: The Two Most Prominent Elements

    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…

  • Axial Seamount Essay

    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…

  • Mount Agung Research Paper

    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…

  • Kilauea Vs Fujiyama Essay

    Hawaii’s Kilauea versus Mount Fujiyama Ever since I was a little girl I have always been fascinated with volcanoes. How do they work? How hot is the lava exactly? Can you travel down into the funnel of a volcano, and if so how and will you survive? And do all volcanoes function the same way? As a child, we never understood that the beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and…

  • Physical Factors Of Volcanoes

    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…

  • Ring Of Fire Analysis

    world's volcano which is 452. The Ring of Fire is 25,000 miles all around, mostly shaped like a horse shoe. Volcanoes can have different way of how the lava runs. Dr. shows comparing to honey and peanut butter with how the lava can run down the volcano. The lava builds us over the side of the mountain. The doctor also explains that the lava can be very thick that it hold pressure. The pressure being gas, it gets trap and eventually it just blows. The pressure is so much, it has to release.…

  • Soufriere Hills Volcano Analysis

    Introduction In this paper the Soufriere Hills Volcano will be analyzes in several different parts; an introduction to the Soufriere Hills volcano, the composition of the magma and lava in the volcano, other characteristics of the magma and lava, ash production from eruptions, pyroclastic flows, volcanic activity before the 1995 eruption, the 1995 eruption, cyclic activity within the volcano, and potential hazards of the Soufriere Hills volcano. Soufriere Hills volcano is located in the…

  • Kidd Creek VS

    Rifting causes thinning and extension of the crust, allowing hot magma to rise from deeper crustal levels and precipitates on the ocean floor as metal-bearing hydrothermal deposits. These deposits are often syn-volcanic faults and fissures controlled. Paragenetic sequence A concept known as the “reconstructive vein” was created by Emmons (1936). The idea of the reconstructive vein is that the veins extends from the deep crustal levels to the surface and reflects a paragenetic sequence of ore…
