Plate tectonics

Alfred Lothar was a famous scientist and lived from 1880 to 1930. He was born in Berlin, Germany. He got a PhD in astronomy but soon wanted to study meteorology and paleoclimatology. He continued his work in Germany and Austria. He was most famous for his continental drift theory. Alfred Wegener stated his theory in 1912. His theory stated that all the continents were once all joined together but slowly drifted apart as time went on. He called it Pangaea. People did not believe him until the…

His idea was even transformed when scientists investigated the sea floor and surprisingly found out that the sea floor were spreading. Plate tectonics theory was born by integrating ideas of continental drift and sea floor spreading, which was established by robust investigation especially with the uses of advanced technologies and techniques, the by-products of World War II (WWII) that enable…

It was found, later that at about 5:36 pm (AST) on the 28th the fault between the Pacific and North American plates had ruptured, thus causing the epicenter of the quake to be 12.4 miles north of Prince William Sound, 78 miles east of Anchorage, and 64 miles west of Valdez. The focus actually occurred at a depth of 15.5 miles. These shifts in the ocean floor…

cause them to decline. Whether it is due to tectonics, climate, a result of both or other factors combined. Thomson (1964) states mountains are over 600meters and this distinguishes it from hills. They are raised parts of the surface of the Earth and one of the simplest classification systems used to determine them was developed by Fairbridge (1968). There are various types of mountains that lie within high mountain…

The Alaskan way Viaduct will collapse if an earthquake happens, but that earthquake will take many steps. These steps will got through the layers of the earth. The layers are stacked on top of eachother, like the liquids in the “Density Column lab”. The layers are inner core, outer core, mesosphere, asthenosphere, and lithosphere(upper rigid mantle, continental crust, and oceanic crust). The earth's compositional layers are inner core, outer core, mantle, and crust. The inner core radiates…

gas,hot magma and ash can escape.The word volcano comes from the Roman name Vulcan the Roman god of fire. Volcanoes are often 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…

or deep? Fourth, explain the type of plate boundary the earthquake from the third question was near and why are earthquakes common to this area? Fifth where was the deepest and the…

There are many methods scientists estimate earthquake probabilities. One technique is using the Global Positioning System (GPS) which permits geologist and scientists to make precise measurements of existing plates in motion. About 1.6 inches per year in the San Francisco area. The history of recent large earthquakes in a specific place helps determine the future of similar great shocks. Another way to estimate the chance of earthquakes occurring is finding…

from the Tasmania in the south to Queensland in the north. In the early Paleozoic to early Mesozoic Australia was located on the eastern side of the Gondwana super continent. It was situated above Antarctica to the northeast of India. The tectonic processes that increased in the size of the Australian continent to the size that it is today are a series of terranes accreted to the continent. The Tasman orogeny is made up of smaller orogenys the Tasman line, Thomson Orogeny, Lachlan…
