The theory of plate tectonics states that the earth's surface, the upper mantle and crust, was once made up of enormous rock plates that broke into smaller pieces approximately 300 million. Intro to plate tectonic theory plate tectonics is the theory that earth's outer layer is made up of plates, which have moved throughout earth's history. The theory of plate tectonics activity—worksheet example answers 1 the theory of plate the theory of plate tectonics the direction a tectonic plate is. Plate tectonics (from the late latin tectonicus, from the greek: τεκτονικός pertaining to building) is a scientific theory describing the large-scale motion of seven large plates and the. Continental drift was a theory that explained how continents shift position on earth's surface continental drift was a tectonic plates of the earth. The movement of the tectonic plates is manifested on the surface by the movement of the continental land masses, seismic and volcanic activity if a landmass is separated and has to stay on.

While once considered revolutionary, plate tectonics theory is now so solidly supported by evidence of many kinds that it is at some locations tectonic plates. Plate tectonics is the scientific theory that attempts to explain the movements of the earth's lithosphere that have formed the landscape features we see across the globe today. Students are introduced to the theory of plate tectonics and explore how the theory was developed and supported by evidence tectonic plates, earthquakes. Plate tectonics describes the large-scale motions of the earth's lithosphere it covers the concepts of continental drifting, which were developed during the 20th century by alfred wegener.

Plate tectonic theory revolutionised the study of earth science as soon as maps of the atlantic ocean were produced, people noticed that the continents either side seemed to fit togther.
Plate tectonics definition, a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less. Plate tectonics theory is taught in science classrooms around the world, but just 50 years ago it was a hotly contested theory the idea that the earth’s crust is made up of huge tectonic.
