Explanation:
Wind can be described by its direction and speed. Wind direction is described using the direction from which it is blowing. Westerly winds move from west to east, while easterly winds move from east to west. Wind speed can be described using measurements like miles per hour or levels on a scale called the Beaufort scale. The Beaufort scale divides wind speeds into categories and uses specific words for different strengths of wind. A “breeze” is a light wind, while a “gale” is stronger. On the Beaufort Scale, the strongest breeze is 31 miles per hour; any wind over 32 miles per hour is considered a gale.
 
        
             
        
        
        
Explanation:
Using a maps scale most of the time involves some math. Usually you'd take a distance on the map (in inches) and multiply it to whatever that maps scale is, for example 1:500. A maps scale is used to show larger distances on a map in a ratio form to show the real ground distance. Showing 10 miles on a single piece of paper would be rather difficult if there weren't a scale
