SNOW, ICE AND FROST 



There are others of God's helpers that work with 

 the rain-water in changing over the earth's surface.

 cannot breathe if the little pores upon the under side 

 are full of water. So when the wind dashes the rain 

 against the side of a cliff it can wear away that cliff 

 much faster than if it fell gently upon it. 



The wind not only drives the rain, but it drives 

 sand also. In the great Desert of Sahara and the 

 Arabian desert the wind wears rocks away very fast
