In curling, players sweep the ice surface quickly with their brooms. This action is not just a habit; it's an important strategy for controlling the flow of the curling stone. When the ice is swept, friction is created between the broom and the ice, which causes the surface to become smoother. This reduces the stone's resistance, allowing it to glide farther with a more predictable trajectory toward a target called the "house." The team that places more stones closer to the center of the house earns higher points.
