A static rope is a low-elongation rope that is designed to stretch minimally when placed under load, typically less than 5%. In contrast, a dynamic rope is designed to stretch up to 40%.  Static ropes have a wide variety of uses, for instance in fire rescue operations  and caving. 
Static ropes have some applications in climbing, such as hauling gear, though lead climbing is always done with a dynamic rope, since a fall on a static rope is stopped too quickly  and may lead to serious injury.   Abseiling, however, is best done with a static rope or with a dynamic rope with low elasticity. 
Bouldering is a form of free climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses. While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems are usually less than six metres (20 ft) tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings.
Figure-eight loop is a type of knot created by a loop on the bight. It is used in climbing and caving
The Flemish loop or figure-eight loop is perhaps stronger than the loop knot. Neither of these knots is used at sea, as they are hard to untie. In hooking a tackle to any of the loops, if the loop is long enough it is better to arrange the rope as a cat's paw.
Climbing protection is any of a variety of devices employed to reduce risk and protect others while climbing rock and ice. It includes such items as nylon webbing and metal nuts, cams, bolts, and pitons.
A double bowline is a type of loop knot. Instead of the single turn of the regular bowline, the double bowline uses a round turn. This forms a more secure loop than a standard bowline.
The International Climbing and Mountaineering Federation, commonly known by its French name Union Internationale des Associations d'Alpinisme, was founded in August 1932 in Chamonix, France when 20 mountaineering associations met for an alpine congress. Count Charles Egmond d’Arcis, from Switzerland, was chosen as the first president and it was decided by the founding members that the UIAA would be an international federation which would be in charge of the "study and solution of all problems regarding mountaineering". The UIAA Safety Label was created in 1960 and was internationally approved in 1965 and currently (2015) has a global presence on five continents with 86 member associations in 62 countries representing over 3 million people.
A rope is a group of yarns, plies, fibers, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine.
This glossary of climbing terms is a list of definitions of terms and jargon related to rock climbing and mountaineering. The specific terms used can vary considerably between different English-speaking countries; many of the phrases described here are particular to the United States and the United Kingdom.
Ice climbing is the activity of ascending inclined ice formations. Usually, ice climbing refers to roped and protected climbing of features such as icefalls, frozen waterfalls, and cliffs and rock slabs covered with ice refrozen from flows of water.
A wide range of equipment is used during rock or any other type of climbing that includes equipment commonly used to protect a climber against the consequences of a fall.
Abseiling, also known as rappelling, is a controlled descent off a vertical drop, such as a rock face, by descending a fixed rope.
Free climbing is a form of rock climbing in which the climber may use climbing equipment such as ropes and other means of climbing protection, but only to protect against injury during falls and not to assist progress. The climber makes progress by using physical ability to move over the rock via handholds and footholds. Free climbing more specifically may include traditional climbing, sport climbing, bouldering and most forms of solo climbing. Free climbing a multi-pitch route means free-climbing each of its pitches in a single session. At the end of each pitch, climbers anchor themselves to belay stations where they can rest.
Lead climbing is a climbing style, predominantly used in rock climbing. In a roped party one climber has to take the lead while the other climbers follow. The lead climber wears a harness attached to a climbing rope, which in turn is connected to the other climbers below the lead climber. While ascending the route, the lead climber periodically connects the rope to protection equipment for safety in the event of a fall. This protection can consist of permanent bolts, to which the climber clips quickdraws, or removable protection such as nuts and cams. One of the climbers below the lead climber acts as a belayer. The belayer gives out rope while the lead climber ascends and also stops the rope when the lead climber falls or wants to rest.
Top rope climbing is a style in climbing in which the climber is securely attached to a rope which then passes up, through an anchor system at the top of the climb, and down to a belayer at the foot of the climb. The belayer takes in slack rope throughout the climb, so that if at any point the climber were to lose their hold, they would not fall more than a short distance.
Rock climbing is a sport in which participants climb up, or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes.
Kernmantle rope is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the core from abrasion during use. This is the only construction of rope that is considered to be life safety rope by most fire and rescue services.
A ropes course is a challenging outdoor personal development and team building activity which usually consists of high and/or low elements. Low elements take place on the ground or above the ground. High elements are usually constructed in trees or made of utility poles and require a belay for safety.
A climbing rope is a rope that is used in climbing. It is a critical part of an extensive chain of protective equipment used by climbers to help prevent potentially fatal fall-related accidents.
A dynamic rope is a specially constructed, somewhat elastic rope used primarily in rock climbing, ice climbing, and mountaineering. This elasticity, or stretch, is the property that makes the rope dynamic—in contrast to a static rope that has only slight elongation under load. Greater elasticity allows a dynamic rope to more slowly absorb the energy of a sudden load, such from arresting a climber's fall, by reducing the peak force on the rope and thus the probability of the rope's catastrophic failure. A kernmantle rope is the most common type of dynamic rope now used. Since 1945, nylon has, because of its superior durability and strength, replaced all natural materials in climbing rope.
An ice screw is a threaded tubular screw used as a running belay or anchor by climbers on steep ice surface such as steep waterfall ice or alpine ice during ice climbing or crevasse rescue, to hold the climber in the event of a fall, and at belays as anchor points.
Craig Luebben was an American rock climber and author. A climber since the early 1980s, Luebben wrote a number of climbing-oriented books, designed the "Big Bro" wide-crack climbing protection device, and was a senior contributing editor for Climbing Magazine.
