## 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), [extent](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-extent.spatial), [surrounded](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surrounded.enclosed)

**Through:** the boundaries together surround a piece of space

**Novel properties:**
- enclosed region
- bounded extent
- spatial containment

## Examples
- The Arctic National Wildlife Refuge spans 19 million acres within Alaska's northern boundary. *(geography)*
- The surface of a neutron star compresses a city's mass into a sphere just 20 kilometers wide. *(astrophysics)*
- Tokyo Station's platform 1 encloses 340 meters of track between its eastern and western walls. *(engineering)*
