I92I. No. II. THE STRANDFLAT AND ISOSTASY. I9 



The final denuding effect of the subaerial erosion during the glacial 

 periods must therefore have been comparatively very great in the much 

 dissected coastal regions, and the islands and peninsulas wer.^ compara- 

 tively rapidly denuded towards sea-level. 



It may also be possible that this effect of the subaerial denudation, 

 was somewhat greater in the coastal regions than farther inland. But it 

 is hardly possible that, under otherwise equal conditions, an abrupt break 

 in the land-slope could thus arise along the boundary between the coastal 

 region and the mountains of the land inside. A strandfiat with a practi- 

 cally horizontal level, like what we now find along the Norwegian coast, 

 could therefore not be formed in this manner without the effective as- 

 sistance of other processes.
