It is concluded that Yellowstone will someday erupt again however, it might not be in the near future. With the myriad of tourists that visit the National Park every year, they had to be sure that it wouldn’t explode soon to ensure people’s safety. Geologists have found that the ground around where the volcano is, is now swelling. The swelling indicates that the underlying magma chamber is refilling once again. But people have other questions, how was this volcano formed? Usually volcanoes…

This essay on supercontinents was a tough piece to write about, but it was fun and I enjoyed writing about it. I had to think scientifically, but I also had to consider the audience on writing this paper. I had to go back and ask myself multiple times if the audience would understand this and be interested in reading this. I had to ask if this was too confusing, and if it was, what could I do to make it clearer and easier for the audience understand. This was probably the toughest essay out of…

to 6 km. The continental crust is quite complex in structure and is made from many different kinds of rocks, much more complex than the oceanic crust. This stucture also known as plate tectonics. Below the crust lies the sense mantle, which is a depth of 2890 km. The mantle consists of dense silicate rocks. It behaves as a fluid, but the P- and S- waves from the earthquakes travel through the mantel, demonstrating that it is a solid. Next, the core, composed of iron and nickel, exists because it…

Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…

Bird tested this theory by using Computer modeling. In his simulation bird based the earth on the 'Jelly Sandwich ' theory which states that the earth 's crust is floating on a layer of partially molten upper mantle which is then underlain by a dense layer of mantle called mantle lithosphere. In Bird 's computer models he was able to adjust variables such as the strength of the lithosphere and the amount of friction generated between the two plates. After testing Bird concluded that even in…

found meeting points of what are called tectonic plates.350 million,or one in 20 people in the world live within danger range of an active volcano.Volcanoes aren’t only found on the boundaries of tectonic plates though,they can also occur over mantle plumes super hot areas of rock inside the…

“I have nothing with this answer, Hamlet. These words are not mine,” for which the king would speak to his son in Act 3, Scene 2 of William Shakespeare’s longest written piece, Hamlet (Hamlet from Folger Digital Texts). As it would appear, among many a reputable scholar these words ring true pertaining to its author. The majority of those well-versed in Shakespearean history theorize that Shakespeare was not the true author of the literary works in his name. Evidence corroborating the claim…

inhabitants thereof. Earth’s surface changes through geoprocesses including volcanoes, earthquakes, and tsunamis. Firstly, volcanoes are one example of geoprocesses that affect earth’s surface. Volcanoes happen when tectonic plates sink down into the mantle, made up of molten rock, melting the rock, which will make its way up to the surface through a series of cracks in the earth. This changes the surface by renewing the materials around which can form new lands, such as the Hawaiian Islands.…

phenocrysts and microphenocrysts that also have oscillatory zoned cores (Murphy et al., 1999). The third type of plagioclase is reverse zoned dusty sieve-textured crystals that have clear oscillatory zoned sodic cores that contain sieve-textured calcic mantles (Murphy et al., 1999). The fourth type of plagioclase found is a very rare and high calcic and normally zoned (Murphy et al.,…

he movement of the tectonic plates causing a shaking of the Earth’s surface, is an earthquake. Seismographs are instruments that can measure the size of an earthquake, from a tremor to a major event, as they are happening almost unceasingly. Some earthquakes can cause major events like broken dams, landslides, volcanic eruptions, tsunamis and destruction of cities. (Encyclopedia Britannica, 2015) The densest areas of the map – appendix 2 – is around Indonesia and New Zealand. This is because…
