The extra words in clues were synonyms of “plate”. In the initial grid, the right-hand side (starting with LEAF BEET) was one row higher than the left side, and “tectonics” could be read in the central column. Applying the principles of plate tectonics to that grid, the left and right sides had to be shifted to align the rows for the final grid. The sums of letter pairs in central cells formed FAULT LINE vertically and MERCALLI SCALE horizontally.
