In curling, friction is reduced by getting rid of uneven particles on the ice's surface.

Friction is not limited to solid surfaces, but also occurs in liquids and gases. Friction depends on the nature of the liquid or gas. For example, it is greater in water than in air. Friction in water and air is also less than friction between solid surfaces that slide against each other. But if this is true, then why is there less friction on ice than on pavement? Both are solids, right?

Why can a person on ice skates move faster on ice than a person wearing regular shoes?
