Alfred Wegener Theory of Continental Drift

The Theory of Continental Drift Continental Drift Discovery The World ALFRED WEGENER

THEORY OF CONTINENTAL DRIFT Found evidence for PANGAEA and proposed the theory of continental drift.

Continental Drift (p95 red book, 182 in Sciencesaurus) Theory that continents were once part of a single landmass that broke apart and have moved to their

present locations. can drift apart from one another and have done so in the past For more information about what the continents looked like throughout the Earths History go to: htttp://www.ucmp.berkeley.edu/geology/anim1.html

Pangaea Pangaea is the name given to the single landmass that was present 200 million years ago Can you name the continents in Pangaea?

http://kids.earth.nasa.gov/archive/pangaea/Pangaea_game.html Recreating Wegeners Discovery Create your own Pangaea using the same evidence Wegener used. K12: Plate Tectonics

WEGENERS EVIDENCE Continents fit together like puzzle pieces WEGENERS EVIDENCE

Fossil Evidence fossils are remains of living things that lived long ago. similar fossils have been discovered in matching coastlines

on different continents. WEGENERS EVIDENCE WEGENERS EVIDENCE Mountains

Some mountain ranges on different continents seem to match. Ex: ranges in Canada match Norway and Sweden Ex: Appalachian Mtn. match UK mtn WEGENERS EVIDENCE Climatic evidence such as glaciers in

areas that are now close to the Equator Evidence of Continental Drift Satellites used to measure the movement of

continents Laser Geodynamics Satellite (LAGEOS) The Plates Move So what now?

Which way? 50 million years
