An ice rink is a smooth, flat surface covered with ice, designed for activities like ice skating, ice hockey, and figure skating. These rinks can be found indoors or outdoors and are typically made from a layer of water that is frozen to create a solid surface. Ice rinks vary in size, with some being Olympic-sized, measuring 60 meters by 30 meters. They are often equipped with boards around the edges to keep players and skaters safe. Many rinks also have seating for spectators and facilities for renting skates or taking lessons.
