Wax to make it simple is slippery, this when placed on the skis reduces the friction between the snow and the skis, (yes there is some friction between skis and snow). The less friction, the faster your skis can glide across the snow, and the faster you go.
Snow + Ancient Footware = Skis
Skiing was invented because some people were having trouble going trough the snow, so they used animal bones that they hunted down.
Skis and snowshoes spread a person's weight out so that they do not sink.
They were invented in 1922.
The were not invented in America, the were invented in Scandinavia.
Weight is distributed over a larger area, so the skis tend not to sink into the snow as much as wheels would. If and when the skis do 'sink' (into powder, for example) their design makes it easier to guide them toward the surface of the snow. Also, the longer the skis, the faster you can travel on them.
snowboards are differnet from skis because skis have 2 skis and a snowboard only has one thing that you stand on.
No but they are better for powder snow
