SKI SPORT SKIING CARTOON POSTER

A ski is a long flat device worn on the feet designed to help the wearer slide smoothly over snow. Originally intended as an aid to travel in snowy regions, they are now primarily used for recreational and sporting purposes. Also, a ski may denote a similar device used for other purposes than skiing, for example, for steering snowmobiles. Snow skis glide on snow because downward pressure, as well as heat from surface friction, melts a thin layer of snow directly under the ski. This creates a very thin layer of water directly under the ski upon which the ski glides. Ski wax is used to decrease drag by increasing the water repellent properties of the base.Like all skis, the original alpine downhill skis were little more than glorified planks of wood.Snow skiing is a group of sports and activities holding in common the use of skis, devices which slide on snow and attach with ski bindings and ski boots to people's feet. Skiing sports differ from snowshoeing in that skis slide, and they differ from ice-skating, water skiing, and in-line skating by being performed on snow. Although snowboarding shares the general characteristics of skiing sports, it evolved from surfing and skateboarding and so is not considered a type of skiing.
