one another. These pieces slowly assumed their present positions as the continents. PLATE TECTONIC THEORY Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. There are seven or eight major plates and many minor plates. Where plates meet‚ their relative motion determines the type of boundary: convergent‚ divergent‚ or transform

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

Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates.
