PPT-Continental Drift Pangaea

All the earth Pangaea split apart and the different land masses or continents drifted to their current locations on the globe httpwwwlearnerorginteractivesdynamicearthdrift3html Alfred Wegener 18801930. Definition. The very slow movement of the continental plates on the surface of the Earth due to tectonic activity through geological time.. What is the evidence of Continental Drift?. Continental Fit. Pangaea. Nearly 100 years ago, Alfred Wegener began an investigation that continues even today. . He wanted to know if Earth’s continents were in fixed (non-moving) positions.. He proposed that all the continents were once part of a supercontinent called Pangaea.. Archiving . and . Publication . of . Scholarly Data . for the Long Tail of Science . Michael Diepenbroek.

The rise and fall of dominant groups. Continental Drift. The continents are part of great plates of the Earth’s crust that essentially float on the underlying portion of the mantle. The World. ALFRED WEGENER. THEORY OF CONTINENTAL DRIFT. Found evidence for PANGAEA and proposed the theory of continental drift.. Continental Drift Theory. Theory that continents were once part of a single landmass 200 million years ago that broke apart and have moved to their present locations. . “What are tectonic plates?. Classifying the Layers.
