What makes the skater move easily on the ice?

Answer 1

things slide on ice easily because the friction of them sliding melts a tiny layer of ice into water, "lubricating" them.

Skaters slide on ice so easily because the metal skates cut into the ice, providing traction, which stops them from slipping and falling. They arrange their feet in a "V" and push left and right with their feet. Since the skates want to keep moving in a straight line, the skater goes forward, as well as their feet spreading apart.
