Plate Tectonics is the theory that Earth's plates are moving around which leads to the formation of mountain ranges, earthquakes and other geological events. In the early Cenozoic the Pacific and the North American plates where separated by first the Farallon plate and then the Juan de la fuca plate. During the Cenozoic, the Farallon plate was being sub ducted underneath the Pacific plate. Once this had occurred the Farallon plate had been destroyed and with this the San Andreas fault line was created. While this was happening new sea floor was being created replacing the old sea bed and also with the plate movement the Baja Peninsula was created while the North American plate was moving against the Pacific plate. The shifting affected the

plate tectonics Essay

Ch. 3 Outline *a key to the curious puzzle was found 50 years earlier by Alfred Wegener, a busy German meteorologist and polar explorer -in 1912 he proposed a theory called continental drift; he suggested all Earth’s land had once been in a single supercontinent surrounded by ocean -he called the land mass Pangaea (pan/”all”; gaea/”Earth, land”) and the surrounding ocean Panthalassa (thalassa/”ocean”) *although he wasn’t first to assemble the continents using geology + geometry…

Plate Tectonics Essay W. Jacqueline Kious and Robert I. Tilling, wrote a book titled “This Dynamic Earth: The story of Plate Tectonic”. It tells us information of people who have explore the world, their discoveries that developed the theory of plate tectonic and how it has progressed through the years. Plate Tectonics is how the Earth’s surface is built of plates. The scientific theory of plate tectonics is that the movements of the large sections form the Earth’s surface. Plate Tectonics has…

Plate Tectonics Press Release GLG/220 November 17, 2014 Leticia Kozbial-Brown Good Afternoon. My name is Leticia Brown and as Director of Earthquake Preparedness for Los Angeles I would like to address public education on earthquake preparedness. Earthquakes happen when the two sides of a fault slip suddenly against each other. The Pacific and North American plates move past each other about one and a half inches a year. The friction between the plates causes…

Plate Tectonics and Continents Essay

Continental Drift and Plate Tectonics Background Continental Drift is the theory that continents move slowly about the Earth's surface, changing their positions relative to one another and to the poles of the earth. In the past the theory has been discussed but not generally accepted, most geologists believing the continents to be fixed in place and subject only to vertical movements, such as those observed during mountain uplift. In recent years, however, a sound body…

Essay on Evidence for Plate Tectonics

Evidence for plate tectonics Some of the evidence that suggests that the continents have shifted to their present positions is: 1. A number of continents have coastlines that appear to fit together like a jigsaw. These are remnants of the super-continents Pangaea and Gondwana 2. Fossils of an animal called Mesosaurus have been found in only two places – South America and Africa. Thus, this suggests that these continents must have been joined at some time. Other fossils, like a certain…

Plate Tectonics Project Your project should thoroughly discuss each of these three questions: Select an area in the world where two plates are interacting and explain what feature can be seen on the surface of the Earth as a result? In the world, there are currently multiple areas in which the interaction of tectonic plates can be represented. I am going to discuss how, as well as provide scientific reasoning to justify the features provided on the surface of the earth due to the Himalayan mountains…
