Skiing was first used as a method of transportation in cold weather over snow. Skiis, which were originally wood planks are bound to the feet using ski bindings. Skiing has developed into a recreational and competitive sport in many countries with a temperate climate.
A ski is a flat device worn on the feet, which help the wearer glide smoothly over the snow. The pressure due to the weight of the person and the surface friction melt the snow under the ski. A thin layer of water is created and the skier glides over it.
Though many skis still have a wooden core, many are made from a number of light weight material like Kevlar, fiberglass, titanium and other composite materials. They are long, thin, pointed and curved upwards at the front to move smoothly over the snow. The ski boots worn by the skier are connected to the skis through bindings, though many manufacturers have started integrating the bindings and the skis.
It is not easy to learn Skiing, and there are many ski schools that teach the various skiing techniques. Initially beginners start skiing under a trained instructor . The terrain is not steep and skiing speeds are low, so there is little risk of injury to the skier.
