Rock climbing is a sport where climbers climb up or across natural rock formations or man-made rock walls with a goal of reaching the summit or other location. Rock climbing requires the use of the climber's hands to hold his or her own weight and not just provide balance. Rock climbing is a physically and mentally demanding sport, that often tests a climber's strength, endurance, agility, and balance. Rock climbing can be a dangerous sport. Knowledge of proper climbing techniques and usage of specialized climbing equipment is crucial for the safe completion of climbing routes. The wide variety of rock formations around the world has led rock climbing to separate into several different styles: bouldering, top roping, lead climbing, free soloing, and indoor climbing. Ice climbing is similar to rock climbing, but requires the use of different gear. Ice climbing is typically done on frozen waterfalls or icefalls.
