Kyoobyung Park October 10‚ 2012 EN101-06 Process Essay How do volcanoes erupt? Volcanoes are created whenever there is an excessive pressure inside the crust of the earth and the pressure of magma extends very high that it finds the way up‚ initiating an eruption. “Sometimes the magma chamber breaks its sides and only reaches to the flank or summit of volcano and sometimes reaches the surface causing an eruption.” That is why a volcano erupts when pressure on the magma chamber causes the

Lava This presentation will discuss two questions which are How is Lava Produced? And What hazards/dangers does lava pose? It will also study one example of a Lava Flow in Hawaii. Lava is molten rock expelled by a volcano during erupting. It is produced/ formed in the interior of planets including Earth and their satellites. When the lava is first erupted from the vent in a volcano otherwise known as the volcanic vent‚ lava is a liquid and varies from 700°C to 1‚200°C. Although lava is

To answer the following question: Relate the generation of all three rock types (igneous‚ sedimentary‚ and metamorphic) to plate tectonics. I will start first‚ with igneous rocks and how does it relate to plate tectonics. Second‚ with sedimentary rocks and progressively keep on answering how all three types of rocks relate to plate tectonics. Will be giving as much information I learned from class. To assure‚ answer is fully answered. The igneous process begins when magma forms by melting at depth

Mount Saint Helen’s Volcano‚ part of the cascade mount range‚ is associated with the subduction zone of the Juan du Fuca plate into the North American plate‚ as is most of the volcanism in this mount range (USGS Geology & History). The eruption intensity is normally quite explosive but Mt. Saint Hellen’s has experienced the peaceful one on occasion (USGS Geology & History). With frequent eruption every couple hundred years (rough estimate at best)‚ Mt. Saint Helen’s is the most active volcano of

Cyndel Van Loh Pd 6 Yellowstone National Park Do you know what area has the most geothermal activity in the world? Even though other places have geothermal activity‚ Yellowstone National Park was established in 1872 and covers the largest area‚ encompasses nearly 3‚500 square miles. The park has Old faithful geyser‚ Lake Yellowstone which is in the caldera of a dormant volcano‚ and the park also has bubbling mud pots‚ hot springs and hot colorful pools. More than half of the world’s geysers are

On the Digermulen Peninsula‚ the succession starts with the classic Neoproterozoic glacial tillite of the Mortensnes Formation (Fig. 3). This tillite has traditionally been tentatively correlated by many workers (e.g.‚ Rice et al. 2011‚ and references therein) with the type ’Gaskiers’ glaciogenic succession in Newfoundland‚ which is between 584 and 582 Ma old‚ based on zircon U–Pb ages from intercalated ash beds (Bowring et al. 2002). The Mortensnes Formation is separated downwards from the ’Marinoan’

The volcano we modeled was Erta Ale. Erta Ale is a active shield volcano. This volcano is located in Ethopia on the continent Africa. This volcano is on two divergent plates. It is the Afar rift that is causing the volcano to continue to be active today. The two plates that are responsible for this are the Nubian and the Somalian plates. Considering this is an active volcano‚ it does produce slow moving magma. The volcano doesn’t have a huge eruption it is small and builds up in the crater and causes

Mini-Literature Review The Ox Mountain range is in County Sligo. ‘’The Ox Mountains lie along Sligo’s border with Co. Mayo’’(Libraries 2010). A strip of ancient rocks - gneiss‚ schist and granite - form the bedrock of the Ox Mountains’’(Geological 2016). The uplands of the Ox Mountains are wild and mainly covered by blanket bog. Some parts of the Ox Mountains are heavily forested. To the north and south of the Ox Mountains is farmland that is mainly underlain by Carboniferous Limestone and Sandstone

INTRODUCTION. Diorite is an igneous rock formed from the partial melting of the crust caused from by basaltic magma from the mantle. It is associated with batholiths‚ dikes and stocks usually around volcanic arcs. Its volcanic equivalent is andesite which is formed from strombolian type volcanoes. DISCUSSION Physical properties: Diorite is a phaneritic rock that is speckled black and white/grey with a very variable colour index of between 40 and 90 over short distances. The rock has an equigranular

The Juan De Fuca tectonic plate is found on the west coast of North America. It is next to the North American plate‚ and according to America’s Tectonics‚ the Juan de Fuca plate is getting subducted under it. This plate is made of oceanic crust‚ but it is also basaltic in some areas. It was named after the pilot and sailor‚ Juan de Fuca‚ an explorer from Europe in the 1600s. The Juan de Fuca plate has a divergent boundary in the Juan de Fuca ridge. New material is made by the Juan de Fuca ridge
