ELEVATION OF THE SEA-BOTTOM 



Fig. 26. — Map to sliow the effect of elevation of the earth's 

 surface on the distribution of land and water in Western 

 Europe. The doubly-cross-shaded area shows what would 

 become dry land if the sea-bottom were raised 600 feet. 

 The Channel, the German Ocean, the Baltic and the Irish 

 Sea, cease to exist. The smaller dotted area would become 

 dry land if the sea-bottom rose another 2,400 feet. Men 

 could then walk from Scotland to Iceland by way of the 

 Shetlands and Faroe Islands. Most noticeable is the great 

 change which would be brought about by the comparative- 

 ly small rise of 600 feet, and the much greater elevation 

 required to change any further the contour of the land.
