## Emergence
**Emerges from:** [touch](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-touch.together), [force](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-force.push), [keep](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-keep.maintenance), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement)

**Through:** touch and force together resist motion to maintain position

**Novel properties:**
- static attachment
- tactile containment
- resisted displacement

## Examples
- A climber's fingers hold the granite edge of El Capitan, countering gravity with friction and muscle. *(everyday life)*
- The Tokamak's magnetic fields hold plasma at 150 million Kelvin in the JET reactor during fusion trials. *(engineering)*
- Tree roots hold soil on steep slopes in the 2014 Oso landslide zone, reducing erosion after the event. *(geology)*
