Plate tectonics

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…

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 are formed between two tectonic plates but Yellowstone is unusual because it lies right in the middle of the North American plate. “That means scientists need a new explanation for Yellowstone’s origins” says Lijun Liu, a geodynamicist. Scientists believed…

found in porphyry copper deposits are gold, silver, and molybdenite. Most porphyry copper deposits can be found along the Pacific Rim and formed during the Tertiary and Quaternary periods. Porphyry copper deposits form through a series of subducting tectonic events, having a copper bearing source, and convection of hydrothermal fluids acting on an igneous intrusion. Introduction Porphyry ore deposits are some of the major resources for minerals such as copper. Porphyry copper deposits can be…

The topic of this discussion is to explain why Africa and South America are moving apart. The drifting apart of Africa and South America has to do with the theory known as the theory of plate tectonics. Based on this model, the crust the coolest part of the mantle, make up Earth’s strong outer layer, known as the lithosphere. Right beneath the lithosphere is the asthenosphere, the hottest part of the mantle. Rocks at this depth are very near the melting temperature, and respond to forces by…

upper mantle are broken into large plates that move slowly. Figure 1 shows the layers of the Earth. Figure 1: Layers of the Earth Plate tectonics The Earth's surface is formed of large pieces of rock called plates that are also called tectonic plates. These plates are always moving; sometimes they slide past one another at other times they collide with one another. History In geologic terms, a plate is a rigid, large and massive piece of solid rock. The word tectonics is derived from Greek…

affect Earth’s surface and the 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,…

Volcanic Application Assignment 1. Which Plate contains the Hawaiian Island-Emperor seamount chain? The Pacific plate contains the Hawaiian Island-Emperor seamount chain. This mountain range is under water mountain range, it reaches above the sea level in Hawaii. Composed a rigid mountain range it is situated in the northwest of Kure and Emperor Seamount. Starched from the northwest to southwest beneath the Pacific Ocean it consists of many seamounts, shallow banks and reefs along the line. More…

results in changes to the earth's surface because of tectonic plates causing mountain building, earthquakes, and volcanos. First off, convergent plates cause many different types of mountains, like the folded mountains. Their called a folded mountain because of the folding plates. The denser plate goes underneath, which will eventually turn into molten, while the lighter one goes on top. This supports the thesis statement because of the two plates causing mountain building. In summarization to…

generally caused by one thing; plate tectonics. All three will be discussed in detail. This paper will describe how they affect each other. This is a very interesting topic because it is so hard to predict. Plate tectonics are interesting in the way they work. This is the constant moving and shifting of the earth’s crust which is divided into segments called plates. They are about the same size as a continent and vary in size as the continents do. Each plate also has various landforms,…

Sciencia is a world analogous to Eath. Based on the present day plate boundaries and similarities on multiple continents, It’s believed that the continents of Sciencia were once together as a supercontinent called Edisonia. The supercontinent held 6 of the 8 modern continents, which broke apart due to tectonic forces in the Lithosphere. Also, the 7th and 8th continents were believed to have formed from volcanic eruptions on convergent plate boundaries. The edges on the modern- day Sciencian…
