  • 1. Lithosphere and Atmospherereviewer for third quarter:EARTH SCIENCE
  • 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

Which of the followingsupported his theory?a.Matching fossil plant remains found ontwo different continentsb.Matching reptile remains found on twodifferent continentsc.nearly identical sedimentary rock typesof same age in widely separatedlocationsd.all of the above
