ISLANDS. 311 



Q. Why are TROPICAL ISLANDS subject to a 

 LAND BREEZE every EVENING (i.e. a breeze blowing 

 from the land towards the sea) ? 



A. The surface of land cools down 

 faster (after sun-set) than the surface of 

 the sea : in consequence of which, the 

 air of the cold land is condensed, sinks 

 down, and spreads itself into the warmer 

 sea air, causing the LAND BREEZE. 



Q. Why is the LAND BREEZE COOL ? 



A. As the surface of the land is 

 cooled at sun-set quicker than the surface 

 of the sea ; therefore, the seaman feels 

 the air from the land to be chill. 



Q. Why is the TEMPERATURE of ISLANDS more 

 EQUABLE than that of CONTINENTS ? 



A. Because the water around the 

 island absorbs the extreme heat of 

 summer, and gives out heat to mitigate 

 the extreme cold of winter. 



Q. Why does the sea round an island GIVE 

 OUT heat in winter ? 



A. Unless the sea be frozen (which is 

 rarely the case), it is warmer than the 

 frozen land ; and, therefore, the warmth 

 of the sea air (mixing with the cold land 

 air) helps to mitigate the intense cold.
