friction
Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.
Kinetic friction is any friction between objects that are in contact and have relative motion. The specific term for objects that roll across other objects is aptly called rolling friction. Rolling friction exerts its force in the opposite direction of its motion.

This question is unclear...let's assume you are comparing a snowboard to a pair of skis, the snowboard usually creates more friction. This is why you see snowboarders clomping along on flat sections, while a skier may glide right through the flat. When ridden specifically on edge, however, a single edge of a snowboard will create less friction than two long skis on edge. In this manner, snowboards can go from creating a lot of friction to almost instantly creating very little. Also, a snowboard ridden straight will create less friction than skis that are angled across the slope, as in a snowplow or a skidded turn. On the other hand, a snowboard turned across the fall line can create an incredible amount of friction, such as when a novice boarder turns the board sideways to go very slowly down a hill that exceeds their ability. Also the wax on your board will change the amount of friction

Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.
Yes it is true.

Friction:)
Friction is a force that opposes motion. As you drive a car along an expressway, the friction from air pushes back against your direction of motion. Also, the friction between your tires and the road (rolling friction) pushes back in the opposite direction of your motion.
