Analysis of the Future State of Geoworld
Cut out pieces as needed from the map on page 13 and use them to reconstruct the
configuration of the plates for the time of the first collision of the Bilbo continent with the
Tape or glue the cut-out pieces onto a blank page, carefully placing them in their correct
positions for the reconstruction.
