View options
  1. Similar fossils were evidence but driving force was weak
  2. There was no evidence and force was complete
  3. There was no coastline evidence and Pangaea was ocean
  4. Tillite was political evidence and Tethys was a city
Hard · Level 28 · continental drift theory,wegener,mesosaurus,fossil evidence,tillite,tidal force
View options
  1. Tidal force was one of the driving forces proposed by Wegener

Hard · Level 28 · academic evaluation,continental drift,plate tectonics
View options
  1. It gave the idea of mobile continents through evidences but the mechanism was later clarified by plate tectonics
  2. It proved Earth completely fixed
  3. It rejected all geological evidence
  4. It explained only modern politics
Hard · Level 29 · continental shelf,jigsaw fit,coastline
View options
  1. Because shelf margins better show the real edge of landmass than coastlines
  2. Because shelf margins form only by rivers
  3. Because coastlines never change
