Plate tectonics

created by many active fault zones within the Earth (Fronabarger). Most earthquakes are made along faults, tectonic plate boundary zones, or even along mid-oceanic ridges (Pidwirny). Small earthquakes can be caused by volcanic activity, landslides, mine blasts, and nuclear experiments (Science Daily). Sun and moon cause tremors by creating tides in Earth 's crust (Live Science Staff). When plates squeeze or stretch, huge rocks shift making faults and causing earthquakes ("Earthquakes"). Faults…

unexpectedly resulted in a volcanic eruption. Lava emerged out of the fissure and began to build a cone shape, which was a volcano. Also, tectonic plates moved through the solid earth in a cycle between the crust and the mantle over very long periods of time. Plate tectonics form the Earth’s crust and are floating above the mantle. The boundaries of the plate tectonics either form mountains or volcanoes from magma beneath the surface, or are subducted and recycled back into the mantle as it…

submarine earthquake is the underwater tectonics of plate or shifting plates of the earth crust. Two blocks of the ocean floor slip past one another and bumping into each other. The reason is the surface of Earth or lithosphere (first two internal layers of Earth) consist tectonic plates which about 50 km to 140 km thick and continuously moving slowly upon a bed of magma in the asthenosphere (third internal layer of Earth) (Pasyanos, 2008). This sudden shift of the plates called fault plane…

Oceanic plates collide with continental plates, resulting in oceanic plate subduction creating volcanic activity most of the time near convergence zones. While, continental to continental plate collisions sculpts flat landscapes into a high chain of mountains, diverging oceanic floors create underwater ridges. Diverging plate boundaries spread plates due to the outward movement, contributed by the upwelling coming from forces…

Have you ever visited Yellowstone National Park and wondered how on earth Old Faithful functions? Or how any geyser functions for that matter? Geysers are mysterious landforms that have the ability to project large amounts of water and steam into the air. One of the most visited geysers is Old Faithful in Yellowstone National Park. Old Faithful is an intricate geyser that erupts at unique times. Throughout this paper, you will learn about how geysers work, learn facts about Old Faithful and it’s…

vulnerable geomorphic landforms. They undergo deformation in response to climatic conditions, human development and tectonic activity quite rapidly. It is not uncommon to see significant alteration to a drainage network in a few decades and in some cases their complete demise creating an urban stream desert (Napieralski, et al). Studying crustal response in environments with active plate tectonics has mainly been used to predict earthquakes and to estimate their impact. Due to the dynamic nature…

1989). For us to understand geological formation of the rift we must look at the history of the tectonic activity of the Rocky Mountains. Background Leading up to the origin of the Rio Grande rift started during the Cretaceous period, approximately 140 million years ago…

oceans don't always change in shape? These are questions that have been asked before. When i explained the idea of how plate tectonics may have been the right answer to these questions i only stated that this could be a reason why the ocean has its shape. Plate tectonics according to google's dictionary is “a theory explaining the structure of the earth's crust…

was still walking among the earth. The eruption of Mount Vesuvius occurred on August 24, 79 AD, and is often referred to one of the greatest cataclysmic events in European history according to our tour guide. Volcanic eruptions and movement of tectonic plates in any state, form, or fashion have the absolute power to kill everyone in close…

beautiful granite formations and glacier-carved landscapes that attract everyone from artists to geologists (Huber, 1987). Yosemite Valley was formed by a series of different forces including volcanism beneath the Earth’s surface, the movements of plate tectonics, weathering and erosion, and glaciation that carved the topography. Description of Yosemite Valley: Yosemite Valley measures seven miles long by one mile wide and the valley…
