Plate tectonics

shores and beaches that tourists can visit. When you visit the beaches, you can take surfing, scuba diving, or snorkeling lessons. Hawaii is diverse in marine life, which includes coral reefs. Hawaii is made up of volcanoes that are a result of tectonic plate disruption. There are two known active volcanoes in Hawaii on the Big Island and the island of Mauna Loa. Tourists can visit volcanoes and learn about how they are formed and how they have made up some of the rich landscape that is Hawaii.…

January 17th, 1994. For many people in this country, it was just a day to commemorate a federal holiday, Dr. Martin Luther King Jr Day . However, to the communities of southern California, it was a day that would change their lives forever. The Northridge earthquake, although given the name of Northridge, was centered in the San Fernando Valley. The earthquake, which happened at 4:31 a.m, had a magnitude of 6.7 and it was felt in places such as Baja California and Las Vegas. This earthquake made…

California Institute of Technology, this earthquake ruptured the greatest fault length of 1500 kilometers. This rupture lasted about 10 minutes long. During this event, there were two tectonic plates that were stuck together (the India Plate and the Burma Plate), which broke free of one another, causing the upper plate to slide back upward, creating…

limestone layer has stripped Vicunia of some material. The detrial mudstone containing Cretaceous fossils lies under a layer of limestone; this limestone will have formed with the presence of skeletal animals, as it did during the Devonian period. Tectonic movement…

The Rock formed began to form during the Jurassic Period with an accumulation of marine life that formed a layer of limestone. Eventually, compression along the Eurasian and African tectonic plates pushed the limestone formation up to the surface. The melting of the glaciers separated the Rock from the rest of African by filling the Mediterranean Sea with water. It is iconic in Roman and Greek mythology because it is known as the Pillar…

there's life in the deep oceans here on Earth, and I mean the deep oceans, two and three miles down, where light has never and will never reach. And this life lives without oxygen, or light, and they do it around deep sea vents, fissures in the tectonic plate, that spew heavy metals and toxic gases at scorching (or boiling, as the case may be) temperatures. These chemicals and metals build up around the fissure and form massive chimney like structures, that will eventually become covered in…

The Puerto Rico Trench, which creates the boundary between the Atlantic Ocean and the Caribbean, is the deepest part of the Atlantic Ocean and lies more than 27,000 feet below the ocean's surface. As the boundary separating two shifting tectonic plates, it lies directly below the island and has been the source of multiple earthquakes that have measured over 7.0. In 1918, a 7.5 magnitude earthquake led to a tsunami that killed more than 90 people on the island, while a 1946 8.1-magnitude…

rocks such as granite, are common in subduction zones on Earth (Wray et al., 2013, 1013). However, in Mars, felsic rocks are nonexistent and only contain mafic rocks. Researcher James Wray et al., (2013) argued that due to the lack evidence of plate tectonics and early forms of magma have been altered by natural causes or buried subsequently, felsic rocks were never present on Mars.…

disastrous and can rip trees out of the ground and can move a building from one place to another. An earthquake i.e. trembling or shaking of the ground is the result of the violent shifting of massive rocks underneath the Earth’s surface called tectonic plates (“My Big Book of Knowledge” 26). Earthquakes can happen on a very high scale, causing between 30,000 and 830,000 casualties during a single earthquake. Earthquakes can be much more dangerous than hurricanes as they can’t be predicted, but,…

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…
