So you can do lots of additions and multiplications, and still have a polynomial as the result. Also, polynomials of one variable are easy to graph, as they have smooth and continuous lines.
Contents-Previous-Next. Effects of wind erosion.  The first effect is the winnowing of light particles. Wind erosion is very selective, carrying the finest particles-particularly organic matter, clay and loam-many kilometres.
First of all, wind alters sound propagation by the mechanism of refraction; that is, wind bends sound waves. Wind nearer to the ground moves more slowly than wind at higher altitudes, due to surface characteristics such as hills, trees, and man-made structures that interfere with the wind.
