## Emergence
**Emerges from:** [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [part](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-part.relation), [inside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-inside.spatial)

**Through:** A boundary limits space and creates a part of that space by defining what is within it.

**Novel properties:**
- bounded region
- interior space
- spatial containment

## Examples
- The Arctic Circle encloses the region where summer days last 24 hours due to Earth's axial tilt. *(geography)*
- The event horizon of black hole M87* marks a region from which no light escapes. *(astrophysics)*
- The Schengen Area is a legal region where internal border checks are abolished among 27 European countries. *(institutions)*
