Most skiers wax their skis for this purpose.
No, sand does not reduce friction but increase friction.
Lubrication to reduce friction. To increase friction step on the brakes.
it rubs against the snow witch causes friction
when you are jumping or making a turn
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction

Air resistance and friction with the snow.
if there is friction on the hill it will slow you down

yes because when they brake the friction is caused to reduce

I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
the factors that reduce in case of friction are the velocity and acceleration.
