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.
Water running down all the mountains and valleys is pulled down by this force of gravity. Wind is ultimately a result of air molecules being held to the Earth's surface due to gravity. Water, wind, and ice, working under the influence of gravity, are the greatest sources of erosion on the Earth's surface. The effects of gravity, combined with wind, water, and ice, create many types of geologic features.
