Plate tectonics (from the Late Latin tectonicus‚ from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motions of Earth’s lithosphere. The model builds on the concepts of continental drift‚ developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were developed in the late 1950s and early 1960s. The lithosphere is broken up into tectonic plates. On

Plate tectonics Intro: The word tectonic represents the meaning of plates and boundaries. As an example of activity is an earthquake‚ which is caused by two plates like the Eurasian and pacific plate pushing towards each other‚ pushing the land upwards causing a mountain as well as an earthquake. The plates are pieces of land that make up the outer crust‚ these could move together‚ move apart or move alongside each other resulting in mountains‚ volcanoes and earthquakes‚ this happens deep

The Pacific Ring of Fire (see below) Tectonic plates of the world. The Pacific Ring of Fire (or just The Ring of Fire) is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40‚000 km (25‚000 mi) horseshoe shape‚ it is associated with a nearly continuous series of oceanic trenches‚ volcanic arcs‚ and volcanic belts and plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes

Discuss the evidence for tectonic plate movement There has been a variety of different evidence for tectonic plate movement but the main evidence was Wegener’s theory which was based on a variety of different evidence from several sciences. Alfred Lothar Weneger was a German polar researcher‚ geophysicist and meteorologist‚ he first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. In 1912‚ he proposed his explanation – the

The initial theory of continental drift was put forward by a German meteorologist Alfred Wegener in 1915. This theory did not seem credible until it was connected with the plate tectonic theory in the mid 1960’s. The Tectonic plate theory had an advantage over previous predictions as it could be supported by observed occurrences. One such thing that supports these two theories is that seen from space the continents look as if they might once have been joined together. This possible idea was then

CONTINENTAL DRIFT THEORY In the early 20th century‚ German scientist Alfred Wegener published a book explaining his theory that the continental landmasses‚ far from being immovable‚ were drifting across the Earth. He called this movement continental drift. Wegener noticed that the coasts of western Africa and eastern South America looked like the edges of interlocking pieces of a jigsaw puzzle. He was not the first to notice this‚ but he was the first to formally present evidence suggesting that
