2 3-1. PLATE TECTONICS 3-1-1. Plate Tectonics? Unified theory of explaining (all) the geological processes (or phenomena) with the dynamics (motion) of the plates (on the surface of the Earth) (tectonics from tectonicus, meaning “pertaining to building”)

3 3-1-2. Histories Theory of continental drift: 16C Abraham Ortellius 17C Francis Bacon 19C Antonio Snider-Pellegrini 1912 Alfred Wegener (1880-1930) – scientifically established the theory Theory of sea-floor spreading Early 1960s, Robert S. Dietz, Harry H. Hess Mantle convection 1928 Arthur Holmes

4 Evidences of continental drift –shape of the continents

5 Evidences of continental drift –fossils

6 Evidences of continental drift – rocks http://www.indiana.edu/~g103/G103/week11/week11.htm
