What type of rope is typically used in rock climbing and mountaineering?

Dynamic rope is specifically designed to handle the forces exerted during a fall. Unlike static rope, which has minimal stretch, dynamic rope can stretch significantly, absorbing the shock of a fall. This elasticity is crucial in climbing scenarios, where a sudden fall can generate substantial forces on the rope and the climber. The ability of dynamic rope to stretch minimizes the risk of injury to the climber and reduces the risk of equipment failure.

Static ropes are more suitable for activities like rappelling or for use in anchored systems where falls are not expected, making them inappropriate for the unpredictable nature of climbing. Escape ropes are designed for emergency scenarios and may not have the same fall-arrest capabilities as dynamic ropes. Accessory cords are typically thinner and used for tasks such as making slings, but they are not intended for climbing falls. Therefore, dynamic rope is the preferred choice in rock climbing and mountaineering for its safety and performance attributes.
