skis work because the way the hot dried wax maks the snow slick for the skis. The skis hot wax does not rub off because your speed.
Skis work by melting the snow under them so they go faster.
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
Skis and snowshoes spread a person's weight out so that they do not sink.
No you don't. However - when you make the turn make sure that your weight is balanced on the front of the skis, so that the back end of the skis do not dig into the ground. This is only effective if you are on hard packed snow, and might not work if it is soft and powdery snow.
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
They use snowshoes to spread out their weight. Skis will also work.
You can snow ski or water ski, but you are always ON the same thing- skis!
