The concept of plate tectonics. It explains that the top-crust of the earth is a mosaic of several rigid segments called plates which include not only the upper crust but also a part of the denser mantle below and are therefore considered as parts of the lithosphere. Plate Tectonics The concepts of continental drift and seafloor spreading are united into a more encompassing theory known as plate tectonics. Earths internal processes were previously thought to operate in a vertical fashion with continents oceans and mountain ranges bobbing up and down without much sideways movement.

Introduction Plate tectonics has revolutionized the way we view large features on the surface of the Earth. The concept of plate tectonics was formulated in the 1960s. The concept of plate tectonics _____.

The theory of plate tectonics states that the Earths solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. The Concept of Plate Tectonics Hardcover March 1 1978 by Ronald V. Plate tectonics is the theory that Earths outer shell is divided into several plates that glide over the mantle the rocky inner layer above the core.

Plate tectonics from the Late Latin. This strong outer layer is called the lithosphere. Though plate tectonics is by no means synonymous with continental drift the term encompasses this idea.

1 The concept of plate tectonics The tectonic plate or lithosphere plate means that it is a huge irregularly shaped rocky plate resulting from the cracking of the solid outer lithosphere of the planet Earth which is called the Earths crust into separate procedures and each plate moves almost as one unit above the Earths mantle. It explains plate tectonics as the driving force behind ongoing changes on Earth. In 1912 German meteorologist Alfred Wegener impressed by the similarity of the geography of the Atlantic coastlines explicitly presented the concept of continental drift.

Key Concepts The idea that continents can move was proposed by Wegener in 1915 on the basis of fossil evidence the way in which coastlines seemed to fit together and other features but it was not widely accepted at the time. According to the theory Earth has a rigid outer layer known as the lithosphere which is typically about 100 km 60 miles thick and overlies a plastic moldable partially molten layer called the asthenosphere. Plate tectonics theory suggests that the continents were once all combined into a supercontinent called 1 __________ with the southern part called 2 __________ and the northern part called 3 __________.
