 hanna (Fig. 281). 



If, on the other hand, the relief 

 of the shore is strong and the sub- 

 sidence is large, the entire coast 

 line will be transformed into an 

 archipelago of steep-walled rocky 

 islets which rise abruptly from the 

 sea (Figs. 282 and 284) . A plateau 

 which is intersected by deep and 

 steep-walled valleys of U-section 

 (p. 341) under large submergence 

 yields the fjords so characteristic 

 of Scandinavia or Alaska. A rag- 

 ged coast line, fringed with islands 

 as a result of submergence, is de- 

 scribed as an embayed coast.
