Tectonics

Mountains are formed by the contact of plate tectonics and mountain building processes such as volcanoes, folding, faulting, igneous intrusion and metamorphism. There are five main types of mountains. The first type is the fold mountain. This is the most common type of mountain. When the plate tectonics come into contact, one plate is thrust downwards and the other is thrust upwards. This creates a thickened crust and represents…

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…

geographic, 80 percent of all the planet’s earthquakes occur along the rim of the Pacific Ocean. Most earthquakes occur at fault zones which means that the tectonic plates slide against each other causing stress between one another. When the two plates rub against each other, they catch on one another. The process is not run smoothly because the tectonic plates push against each other without any movement. After a while, the rocks break because of all the pressure that's built up.This happens…

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 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…

Dynamic Planet is an amazing branch of science. From oceanography, to currents, to plate tectonics, all of the subtleties of the dynamic planet are unique in their own ways. Our Earth, itself, is a dynamic planet. The planet contains over one thousand volcanoes, forty thousand earthquakes, and almost two hundred impact craters. All of these features come from the Earth constantly being in motion. The Earth has powerful forces that are caused by nature. Most of which can’t be seen but felt…

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,…

Guadalupe Mountains, and the Davis Mountains. The Rio Grande Rift expands from Colorado all the way to Chihuahua, Mexico. Earth surfaces began to pull apart around 30-35 million years ago. In this process, there were volcanic activity and moving of tectonic plates that have created much of what you can see today in the region. This includes many mountain ranges, the Rio Grande River, and Potrillo Volcanic Field. The Rio Grande Rift is still active and moves between .5-2mm per…

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 research studies reveal the changing dynamics and showed that earth is left as the only planet in the solar system with the movement of tectonic plates. The studies also show that the planets like Mars and Venus had the same types of plates but they have not been detected for a long time. According to the geologists the major tectonic plate in the earth’s crust are Eurasian, North American, South American, the African, the Antarctic, Pacific and Indoaustralian plates. However along…

Kennedy (1964) to designate the peak of a wide spread orogenic thermo-tectonic episode characterized by intense period of reactivation and crustal formation. The term Pan African Orogen was used to describe the structural differentiation of Africa into cratons and mobile belts during the Neoproterozoic to earliest Paleozoic time (Kennedy, 1964). However, Kröner (1984) reformulate the term Pan-African to describe the tectonic, magmatic, and metamorphic activity of Neoproterozoic to earliest…
