Evidence of plate tectonics essay

Read this Science Essay and over 88, 000 other research documents. The Plate Tectonics Theory. For millions of years, tectonic plates have been determinate of changes in the physical face of the earth, and they 2. Evaluating Evidence for Continental Drift The Plate Tectonics theory states that the outer layer of the earth, or lithosphere, is separated into different large slabs called plates, which are holding the continents and oceans.

Plate tectonics is a combination of two ideas, seafloor spreading and continental drift. The creation of new oceanic crust at midocean ridges is called seafloor spreading. In 1969, spreading plate margins became part of the theory of plate tectonics. plate tectonics Essay. hotter which means its also denser the core has two parts; the outer core is a dense, viscous liquid and the inner core is a solid with a maximum density about 16 gcm3, about 6x that of granite rock.

Describe geographic evidence collected in the last part of the 20th century to support the theory of continental drift. Some of the geographical evidence collected in the last part of the 20th century to support the theory of the continental drift is the discovery of plate tectonics Hess and Deitz Plate Tectonics essaysPlate tectonics is a recently developed science, and it can be used to explain a lot of phenomena on the Earth, such as earthquakes. There are actually two big fundamental theories of plate tectonics.

One of the basic theories is called continental drift, and the other one is t 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. Essay On The Evidence That Supports The Theory Of Continental Drift And Plate Tectonics EVALUATE HOW PLATE TECTONICS THEORY HELPS OUR UNDERSTANDING OF THE DISTRIBUTON OF SEISMIC AND VOLCANIC EVENTS In this essay I am going to look in detail at plate tectonic theory and how it can be used Plate Tectonics is a scientific theory which study how the Earths plates are driven and shaped by geological forces to keep them in constant movement.

The theory explains the presentday tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity Fossil Distribution. One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses.

It suggested that those land areas had in the past been connected.
