3. Removable bolt - Wikipedia

   en.wikipedia.org/wiki/Removable_bolt

   Removable Bolts negate the need to install permanent protection bolts to the wall, which can be costly and cause cosmetic damage. RBs are designed for use in bolting new sport climbing routes , setting temporary anchors on traditional routes, and on back-country expeditions where abandoning gear or placing permanent gear is not optimal.

[5] To set up this anchor the belayer should place a piece of directional protection (i.e., a nut or cam) into a crack below their body, or tie themselves by the belay loop to a rock or tree.

6. Earth anchor - Wikipedia

   en.wikipedia.org/wiki/Earth_anchor

   Single helix earth anchors Guyed mast anchor. An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.

7. Bolt (climbing) - Wikipedia

   en.wikipedia.org/wiki/Bolt_(climbing)

   In rock climbing, a bolt is a permanent anchor fixed into a hole drilled in the rock as a form of climbing protection. Most bolts are either self-anchoring expansion bolts or fixed in place with liquid resin. Climbing routes that are bolted are known as sport climbs, and those that do not use (or allow) bolts, are known as traditional climbs.
