Plate Tectonics Theory Explained In Detail Ppt The document discusses plate tectonics and the structure and dynamics of the earth's interior. Plate tectonics • history of plate tectonics and continental drift 1. abraham ortelius (1596 ) continents fit like jigsaw puzzle ortelius suggested that the americas were "torn away from europe and africa . . . by earthquakes and floods" and went on to say:.
Plate Tectonics Theory Explained In Detail Ppt This browser version is no longer supported. please upgrade to a supported browser. This ppt on plate tectonic theory explains the scientific concept behind the movement of earth's lithospheric plates. it covers key features such as plate boundaries, types of plate movements (convergent, divergent, and transform), and the role of tectonics in earthquakes, volcanic activity, and mountain formation. Each type of interaction produces a characteristic “tectonic feature”, like mountain ranges, volcanoes and (or) rift valleys, that we will discuss during this lecture. There are several types of plate boundaries that describe their interactions as they move: convergent where they collide and form mountains; divergent where new crust is created at mid ocean ridges; and transform where they slide past each other.

The theory of plate tectonics explains how plates and their continents move. convection current theory of plate tectonics 1. evidence from the sea floor 2. causes of plate movement 3. putting the theory together key concept summary 34 plates move apart. 3.3 iii. plates move apart. divergent boundary a. tectonic plates have different boundaries. What are tectonic plates? a plate is a large, rigid slab of solid rock. plates are formed from the lithosphere: the crust and the upper part of the mantle. the plates “float” on the slowly flowing asthenosphere: the lower part of the mantle. the plates include both the land and ocean floor. Earthquake distribution map distribution of earthquakes mirrors the tectonic boundaries. benioff zone deeper earthquakes are always found far inland of the trench. 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.
