THE SUN AND ITS EFFECT ON 



THE CLIMATE. 



The location of the earth with regard to the sun 

 has a very material effect upon the climatical condi- 

 tions of our planet. The earth being forced to revolve 

 on its axis by the action of heat and cold, it likewise 

 is forced to move around the sun from the same cause. 

 In each case the greatest force being manifest upon the 

 plastic properties of matter, that is water and air. 



Air and water being the more plastic properties of 

 the earth's makeup and in consequence they become 

 our study. 



When the earth passes to the north of the sun 

 marking the equator out against space north of the sun, 

 leaving the sun south with regard to the northern hemi-

The sun in this case being situated south of the
