Volleyball is a versatile sport that is played in both indoor and outdoor environments. Indoor volleyball is played on a hard court, typically in a gymnasium, while outdoor variations, such as beach volleyball, are played on sand. Because the sport has established rules and professional competitions for both settings, it is correctly categorized as both indoor and outdoor.
