## Emergence
**Emerges from:** [water](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-water.liquid), [land](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-land.geography), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [portion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-portion.share), [side](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-side.surface)

**Through:** water and land together form a bounded portion of water

**Novel properties:**
- partially enclosed water body
- interface between land and sea
- asymmetric shoreline enclosure

## Examples
- San Francisco Bay shelters the city of San Francisco and connects to the Pacific Ocean through the Golden Gate Strait. *(geography)*
- Chesapeake Bay supports over 3,600 species and spans parts of six U.S. states, fed by rivers like the Susquehanna. *(ecology)*
- The Bay of Bengal receives the discharge of major rivers including the Ganges and Brahmaputra, forming a vast deltaic region. *(hydrology)*
