  1. 1. Lithosphere and Atmospherereviewer for third quarter:EARTH SCIENCE
  2. 2. The observation that the continentsfit together like puzzle pieces, andmay once have been connected, ledAlfred Wegener to propose a theoryin 1910 calleda. continental plowingb. continental driftc. wandering continentsd. shape matching of continents
